Modern Serbian Armor

M09 105 mm Armored Truck-Mounted Howitzer

Republic of Serbia (2009)
Self-Propelled Howitzer – Possibly Only 1 Prototype Built

After Serbia became independent in 2006, its Army inherited stocks of various equipment and weapons left over from Yugoslavia. These included older artillery pieces, such as the 105 mm M-56 howitzer. Given the availability of this howitzer, the engineers from the Serbian Yugoimport company tried to develop a self-propelled vehicle equipped with this gun. In order to make the whole project as cheap to develop as possible, this howitzer was simply placed on a modified military truck chassis. This created a vehicle known as the M09 105 mm armored truck-mounted howitzer.

History and Context of the Project

During the mid-2000s, the Serbian Army began to be interested in the development of cheap self-propelled vehicles that could be built using available components, such as the chassis and the main weapon. The Yugoimport company began building and developing a series of such vehicles. Yugoimport (Југоимпорт СДПР Ј.П) was founded back in 1949, with the intention of acquiring the necessary military equipment for the JNA (Jugoslovenska Narodna Armija, Yugoslav People’s Army) from abroad. After 1953, Jugoimport expanded the scope of its business to the export of domestic military equipment. In 2006, Jugoimport was reorganized and became a Serbian state-owned public enterprise.

One of their projects included installing the aging 105 mm M56/33 howitzer on a 6×6 truck chassis. While using a tracked chassis would provide better off-road driving capabilities, it would also raise the price and prolong the development time needed to build such a vehicle. A truck chassis, on the other hand, was quite cheap and could be easily adapted for this role. The gun choice mainly lay in its availability and, while it lacked sufficient firepower, it was hoped that its rate of fire would make up for this shortcoming.


The official designation for this vehicle was the M09 105 mm armored truck-mounted howitzer. For the sake of simplicity, this article will refer to it as simply M09.

Development of the M09

Unfortunately, the M09 is quite poorly documented, especially regarding its development history. It appears to have been a private venture of Yugoimport as an attempt to create a cheap self-propelled vehicle. The M09 was intended to provide fast mobile fire support to rapid deployment forces of different unit strengths, from brigade to battalion level. Thanks to its small caliber and large ammunition storage, it was meant to saturate the designated target with sufficient firepower before retreating to avoid any potential counter-response from the enemy. Another interesting feature is that its low overall weight allowed it to be transported by air. The sources do not specify the precise time during which the whole project was carried out. This vehicle name M09 gives an indication that its development likely began sometime at the end of the 2000s.

One of the first public appearances of the M09 was during the ‘Partner 2011’ (Партнер) Arms Fair held in the Serbian capital, Belgrade. While some sources mention that the M09 was first publicly shown during the military fair in 2013, this is not true, as there are photographs of it from 2011.

Technical Characteristics


The truck chassis which was used for this vehicle is not listed in the sources (as are, in general, all other major details). Given its appearance, it was likely based on the FAP2026 BS/AB 6×6 all-terrain wheeled truck. This was a vehicle domestically developed and built by the FAP (Fabrika Automobila Priboj) factory beginning in the late 1970s. It was primarily designed to act as a towing vehicle for a number of artillery pieces. It could also be used to transport troops and materials, with up to 6 tonnes capacity. The M09 could be customized to use on any available 6×6 military truck chassis for potential buyers.

The M09 chassis was probably reinforced and strengthened in order to withstand the firing recoil of the main gun. The M09 was a light vehicle, at only 12 tonnes. Its maximum speed was 90 km/h, while the operational range was 450 km.

Main Armament

The main armament chosen for this vehicle was the 105 mm M-56 howitzer. This weapon was domestically produced during the 1950s in Yugoslavia. It was developed mostly using components from the German 10.5 cm leFH 18/40 but also modified to be able to use ammunition from the American M2 howitzer. Some of these survived up to the 2000s, when they were modernized, receiving new ammunition, a longer barrel, and modifications to breach lock and muzzle brake. The maximum firing range, depending on the ammunition used, was from nearly 12 km to 18.1 km. The modified howitzer was designated the M-56/33.

During the installation of the M-56/33 howitzer on the M09, its wheels and trail legs were removed. The main weapon was placed to the rear of the truck chassis, where the previous flatbed was replaced with a simple flat firing platform. The howitzer was then placed on a simple round-shaped mount which allowed full rotation of this weapon. The gun and its crew were protected by an enlarged gun shield that fully protected them from the front and sides.

The elevation of the M09 main gun was -10° to +62°. While the M09’s main gun could make a 360° turn, its firing arc was actually facing to the rear. Firing to the sides or front (over the crew compartment) could potentially overturn the vehicle. As there was no automated loading system, each round had to be loaded manually. The firing speed was 6 to 7 rounds per minute.

The ammunition load consisted of 60 rounds. These were stored in two storage bins located just below the armored crew compartment. During traveling, the gun would be positioned between the two ammunition storage bins.

Given its relatively small weight, in order to provide stability during firing, two manually operated support legs had to be lowered. In addition, there are two small stabilizers located to the rear, and these too had to be manually lowered. Despite this, with a skilled crew, the M09 needed some 2 minutes to deploy. The reverse process was a bit longer, at 2 minutes and 30 seconds. The manual lowering/raising of the support legs left the crew exposed from potential enemy counter-fire.

Prior to firing, the crew had to disembark and manually lower or raise each of the four supporting legs. Source:

For self-defense, the M09 was provided with a small manually rotating turret armed with a 12.7 mm heavy machine gun which was mounted on top of the crew compartment. This small turet was protected from the front and back and had open sides and top. Based on the photographs during its development, two types of turrets were employed. Initially, the front of this turret was protected by angled two-piece armor. The later version had a much simpler one-piece angled armor. The armament itself was also changed. Initially, a 12.7 mm Browning was used, later being replaced by a domestically produced M87 of the same caliber. Besides the heavy machine gun, the crew was also armed with their personal weapons.

At some point, the turret would be slightly redesigned, incorporating a domestically-built heavy machine gun. Source:


The M09’s main driver compartment was protected from 7.62 x 51 mm NATO caliber rounds and shrapnel. The gun and the gun operators were protected by a larger gun shield. The M09 was quite lightly armored, its speed and mobility being its best defense.

Crew Compartment

The M09 crew compartment was placed at the front of the vehicle and it also covered the whole engine compartment. The crew compartment had a simple box shape, with the top slightly curving inwards. This area also received a number of modifications during the vehicle’s development history. Initially, the front armor plate was placed at a high angle, which offered better protection. This design was not accepted for some reason, as it was replaced with a more box-shaped front. There were two doors on opposite sides for the crews to access it. Besides the larger two-piece windshield, there were also four smaller windows placed in pairs on each side, two of which were on the doors. Behind the crew compartment, two ammunition storage bins were placed.

The M09 had a crew of five. However, sadly, the sources do not specify the precise role of each one. The roles likely included a commander, a gunner, a driver, a loader, and a gunner assistant. These would be seated inside the front protected cabin when driving. The rear gun compartment had room for three crew members. The gunner was positioned to the left of the gun, with the gunner assistant on the right and behind them the loader. The gunner assistant manually opened and closed the breechblock and may have also helped the loader. The gunner assistant could fire the gun. The gun platform was quite cramped, with limited room for the operators. They were placed on two seats that were connected with the whole gun mount, so they rotated with it. The commander and the driver would remain in the crew compartment. The commander probably was the one that operates the top-mounted machine gun.

The Fate of the Project

How many M09s were built is unknown, but likely only a single prototype was constructed. The M09 was presented on numerous military fairs and exhibitions after 2011 but failed to gain any foreign interest. The Serbian Army also did not adopt it, mainly because it was more focused on the larger and more advanced NORA self-propelled series. One of the recent events where the M09 was presented was during a visit by a military delegation from the Kingdom of Bahrain held in Serbia in April 2021. As the M09 did not gain any foreign interest and it appears that it will not be adopted by the Serbian Army, its final fate currently is unknown, but it is likely that it will be abandoned.

The much smaller M09 can be seen in the left corner of this picture. It is dwarfed by the two larger NORA self-propelled guns. The NORA is much better armed has a better overall design and even achieved some export success while also being adopted for service in the Serbian Army. Its smaller cousin’s fate is uncertain. Source:


The M09, while being designed to be cheap and simple to operate, did not manage to gain any foreign interest. Given that it uses an outdated and generally weak main gun, this is not surprising. While it is not uncommon to find manually loaded self-propelled guns, modern armies have gravitated more and more towards much more sophisticated weapon systems than the M09. Armies that have smaller budgets may find the M09 appealing, but for now, none have actually shown interest in it. While its final fate is uncertain, it is likely that it will remain just a simple proposal and testbed for the Serbian engineers.

Modern Serbian Armor


Republic of Serbia (2016)
Remote Control Unmanned Platform – 10+ Built

In recent years, most modern armies around the world have become increasingly interested in developing remotely controlled vehicles and aircraft. These vehicles are intended to perform various combat roles, ranging from reconnaissance, logistics, or probably most importantly, direct combat operations. These were developed in the hope to supplement or even replace human soldiers in dangerous situations, thus reducing the risk to human life. The effectiveness of these vehicles is shown during the ongoing war in Ukraine. The use of drones has especially gained huge media coverage.

The Serbian Army entered this new arms race by initially introducing the short-range anti-tank system named Милица (Eng: Milica – a Serbian female name). It was, in essence, a small remotely-controlled tracked vehicle armed with two anti-tank launchers. While it was not adopted for service, further development would lead to the Милош (‘Miloš’ in the Latin script) Даљински Управљива Безпосадна ПлатформаДУБП (English: Milosh – a Serbian male name – Remote Control Unmanned Platform) which entered service with the Serbian Army in small numbers.

The Milica Predecessor

Prior to Miloš, the first Modular Robotic System vehicle under the name Milica was developed by Jugoimport, one of the major Serbian arms and weapons manufacturers. During the late 2000s, Jugoimport was also involved in developing a number of remote-controlled systems meant to perform different tasks, ranging from surveillance to anti-tank operations.

Milica was primarily intended to provide infantry with a remotely controlled anti-armor close support system that could engage modern MBTs (main battle tanks). It could also be used to engage and destroy an enemy firing positions and fortifications. The Milica system was intended to be fully modular, which meant it could be adapted to fulfill various combat roles, but also secondary non-combat duties. Other roles included helping infantry with gathering intelligence, monitoring and observing areas that were not yet fully secured, transporting spare equipment and ammunition, and even transporting wounded soldiers. While a fully working vehicle was built, no production orders for this project were ever issued. In order not to waste the resources and time used to develop this vehicle, its chassis was reused for another project, the Miloš.

Interestingly, way back in 1985, during a military exhibition of various weapons and equipment held in Belgrade, an unusual remote control platform was presented, described as being named ‘Hunter’. This vehicle was designed to relocate unidentified explosive devices to save distance. While not much is known of this vehicle, its hull design somewhat resembles that of the later built Miloš. If this vehicle in any way had an influence on the Miloš project is unknown, but it seems unlikely given its huge time differences of over 30 years.

This vehicle, while sharing some resemblance, it is highly unlikely that its design had any influence on the later Miloš project. Source: Screen shot from the Sredstva nase odbrane TT zbor nakon parade 1985 1 deo Yotube video

Miloš’ Development History

The Milica project, in the end, led to no production order either by the Serbian Army or aboard. Nevertheless, it provided Serbian engineers with key experience in designing such vehicles. It also offered a good starting point for a series of new improvements. Based on its initial development, work on improving the overall performance was undertaken by Војнотехничког институт VTI (English: Military Technical Institute). Прва Петолетка – Наменсka ППТ (PPT) would also later join in. This firm specializes in the modernization and production of small-arm weapons. It is also involved in the production of some new Serbian military vehicles, such as the PASARS-16 mobile anti-aircraft platform.

The available sources do not offer much information on the development process. What is known is that the project was initiated in 2016. The main aim of this project was to provide the Serbian Army with a remote control unmanned platform. Initial plans did not include that this vehicle would be used as an export opportunity. Instead, it was specially designed to fulfill the needs of the Serbian Army.

To make the new starting point easier and cheaper, the new designers initially reused the Milica’s chassis. While the armament of the Milica was sufficient to deal with tanks and fortified positions, it lacked any means to combat enemy infantry formations. This role was intended for the new vehicle, and for that reason, the armament was to be replaced with one machine gun and grenade launcher. With this new armament, the main purpose of this vehicle was to provide fire support for Serbian special forces during an engagement against enemy infantry groups or positions at ranges up to 800 m. Armament aside, the whole chassis, suspension, and superstructure would be completely redesigned. Initial work was mainly focused on experimenting with different armaments on the Milica’s chassis. Further work led to testing a new suspension that incorporated fewer but larger independent torsion bar-suspended road wheels.

At some point, the original Milica’s chassis was redesigned and replaced by a much smaller and possibly simpler design. The four-road wheel suspension was used, but the design of the wheel was slightly changed. The drive sprocket was moved to the rear, and the idler was placed to the front. In addition, due to technological advances, the bulky superstructure was also completely removed. This new vehicle was presented for the first time to the public during the military exercises Челик 2017 (English: Steel).

Miloš during its first public appearance in 2017.


This vehicle is known by the name Miloš. It is also referred to as Miloš-N, with the N standing for Наоружани (English: Armed). In the media, it is sometimes called Мали Милош (English: Little Milosh). The vehicle class is referred to by various designations, such as an Unmanned Ground Vehicle, Remotely Controlled Unmanned Platform, or simply a Drone. As the Serbians use both Cyrillic and Latin scripts, this article refers to it as Miloš.


Given its recent introduction, the Miloš overall design has often been prone to various modifications and improvements. Because of this, its current form may receive additional changes in the future. What is more, due to being a new combat platform, more precise information on its construction is likely to be unavailable to the public yet.


The simple box-shaped hull is fully enclosed and was built using welded steel armor with a combination of screws. These hold the upper plates in place so that they can be easily removed for maintenance and repairs in the field.

While there is limited information on its interior, based on the available pictures, the hull can be seen divided into a few sections. The transmission has been placed on the rear. The electric motor, batteries, and other equipment needed for controlling and powering the main weapon system have likely been stored in the remaining part of the hull. Two cameras (one in front and one to the back) have been placed on the hull. It also has what appears to be a pair of towing hooks placed on the front and the rear of the upper hull.

The Miloš base consists of a simple box-shaped hull. While most of its parts have been connected using welding plates, the upper plates are connected to the hull with screws. This provides easier access to the interior in case of repairs or maintenance. Source: Wiki


The suspension consists of four road wheels. These are independently suspended with torsion support units. Further, there is a rear-mounted drive sprocket, rear idler, and two return rollers. Thanks to the use of an electric motor, small size, and rubberized tracks, Miloš provides the possibility of approaching enemy positions quite stealthily.

The Miloš used a simple torsion bar suspension which consisted of roar road wheels. Source:

With this suspension unit, the Miloš is capable of reaching a vertical elevation of 25° and a side elevation of 20°. Crossing a 2.5 m wide trench is also possible. Ground clearance of this vehicle is 200 mm. Given its small size, it is possible for it to be used inside buildings (that have entrance points at least 80 cm wide) by climbing staircases.


This vehicle is powered by an unspecified electrical motor connected to 60 to 84-V strong lithium-ion batteries. With a weight of 650 kg, its maximum speed is 7 km/h. The effective operational autonomy ranges between 2 to 8 hours depending on the current mode it is used for. For example, when stationary and used for observation or shooting, the operational range goes up to 8 hours. When in movement, the operational range is 2.5 hours, and movement-observation-shooting decreases its operational use to 2 hours.

Given its small size, the Miloš can be easily transported by using a simple trailer. Source: Wiki


While the Milica incorporated a highly angled but bulky superstructure, the engineers that worked on Miloš, decided to completely remove it from the Miloš. With new technologies, it was possible to place the automotive parts inside the hull. This made the whole design much easier to build.

Milica used a fairly bulky superstructure that housed the most important components. Source:


The Miloš’ turret acts as a firing platform for the main armaments with spare ammunition, optic sights, signal antennas, a control management panel, and a fire control system. The turret known as Даљински Управљана Борбена Станиица – ДУБС (English: Remote Control Combat Station – RCCS) was developed by the PPT to be used as an axillary firing platform for armored vehicles. This turret is also used on the new Командно Извиђачкао Возило КИВ (English: Command and Reconnaissance Vehicle – CRV) based on the BOV-3 4×4 vehicle.

The new command vehicle is based on the BOV-3 with a similar turret that was used on the Miloš project. Source:

The Miloš’ overall design changed during its development. Initially, a much smaller turret was used, replaced by a somewhat larger design. Besides the obvious changes to the dimensions, the position of the grenade launcher and the optic unit were repositioned. The current version has a weight of 275 kg and is powered by 24V batteries.

The later version incorporated a somewhat larger turret. Source:


When the Miloš project was initiated, it was primarily intended to deal with targets up to 800 m away. For this, a 7.62 mm M-86 machine gun was used as the main armament. To further increase firepower, a 40 mm grenade launcher was also added.

Main armament consists of one machine gun and one grenade launcher. Source:

As the Miloš’ development continued, the armament and ammunition storage position received some changes to the overall design. The machine gun was positioned inside the small turret. Initially, it was placed inside the turret, almost covering it completely. Later, the machine gun was placed further to the front of the vehicle. The position of the ammunition box magazine with a capacity of 500 rounds received some changes. At first, it was placed next to the machine gun and fed it directly. The later improvement led to the introduction of the somewhat larger turret, which also required some changes to the magazine’s design. The magazine on the new version is placed sideways and fed to the machine gun by a guiding rail. To avoid potentially damaging (although the chanse for that is minimal) the vehicle, a spent cartridge box is placed in front of the turret. The M-86 is a gas-operated machine gun intended to be used as a coaxial or mounted on an armored vehicle. It is activated electrically and has a firing rate of 700 to 800 rpm.

This version had a completely resigned feeding system and ammunition storage magazine which is placed sideways. Source:ša/

The grenade launcher was initially placed on the left of the machine gun. It would be repositioned to the rear and slightly above the machine gun. It uses a six-round drum magazine. This launcher had a maximum effective firing range of up to 375 m.

Early on, the grenade launcher was placed left of the machine gun and was completely exposed. It would be repositioned just behind the machine gun. Source:

Recently, the Miloš has adopted to mount two 64 mm M80 Зоља (English: Wespe) rocket-propelled anti-tank grenades. The M80 Зоља is a disposable, cheap, and easy-to-use anti-tank weapon developed during the early 1980s. While maybe a bit outdated, it is still useful in engaging enemy light armor and fortified positions. The combat-effective range of this weapon is 200 m while the maximum range is up to 400 m. It is capable of penetrating some 300 mm of homogeneous armor. With a weight of 3 kg, it could be easily carried by one man, so mounting two such weapons on Miloš was not a major issue. These two are located on the Miloš’ left turret side. In this case, the original armament is still retained, greatly increasing its combat effectiveness. The use of the M80 appears to be temporary as better weapons systems are currently in development.

All weapons on the Miloš are linked together and can not be operated at different targets independently. The whole turret can achieve a full 360° rotation, while the elevation of the weapon systems is -15° to 50°. The Miloš’ operator can adjust the rotation and elevation speed to suit different needs. The rotation speed ranges from 0.05°/s to 48°/s, while the elevation speed 0.05°/s to 28°/s.


Not much is yet published about the Miloš’ overall protection. What is known is that this vehicle is protected against small caliber rounds from 5.56 mm to 7.62 mm. Another layer of defense is the vehicle’s own small size. Its length is 1.7 m, width 0.77 m, and height 0.95 m. As the Miloš’ development progresses, other modifications intended to increase its survivability may be introduced.

Control and Optics

The Miloš is provided with a charge-coupled device – CCD camera with a maximum zoom of 30x. With this camera, the Miloš’ operator is capable of spotting an enemy soldier at up to 1 km distance. Miloš also possesses a night vision-thermal camera that has a zoom of up to 4x. Using it during the night, an enemy soldier can be spotted at 450 m. In addition, it also incorporates a laser range finder with a maximum operational range of up to 2 km. Lastly, Miloš has a meteorological sensor connected to the firing system. Its purpose is to provide information such as wind speed and azimuth for better correction of fire.

Miloš is remotely controlled using a fixed control panel that is located in a command vehicle. Another option is to use a small portable control panel that is operated by one operator. In this case, great attention is given to this control panel to be as easy to use as possible. During good visibility on an open field with few obstacles, the Miloš can maintain operational communication with its operator at ranges up to 3 km. In cities or on bad terrain where visibility is reduced, the visual operational communication with this vehicle is around 1.5 km. In a non-visual situation, its command operational range is 500 m. Lastly, the operator is also provided with an ammunition counter indicator, to help keep track of the spent ammunition.

The Miloš needs only one operator to be fully functional. This operator can stay behind at great ranges up to 3 km when there is enough visibility. Source:


In 2021, the PPT presented two new versions of the Miloš. The first version is intended to provide an increase in overall performance and firepower. The second version was to act as logistical support by transporting equipment and ammunition or even wounded soldiers. Both versions are currently at the prototype stage and their production numbers are likely small.

Miloš V2

Further development into the Miloš project led to the creation of a new prototype named Miloš V2 (the original Miloš is marked as V1). It incorporates a number of modifications and improvements. The obvious change is the use of a five-road wheel suspension. The length of this version is 1.87 m, width is 0.96 m, and the height is 0.95 m. Improvements to its automotive drive unit allow for an increase of maximum speed of up to 15 km/h despite the weight being increased to 750 kg.

In addition, the armament was replaced by a 12.7 mm heavy machine gun and two 9 cm M79 anti-tank rocket launchers. The 9 cm M79 with a maximum firing range of 650 m is capable of penetrating 400 mm of rolled homogeneous armor. Further development is to include Russian Kornet missile launchers. The Miloš V2 RCCS (without the two M79)  was tested as part of the M-84AS1 prototype upgrade package

The Miloš-L, the L-stands for Логистика (English: Logistic) is an unarmed version of this vehicle. Its main purpose is to act as a support and auxiliary supply carrier vehicle. It has a towing capacity of 200 kg, either in supply or transporting wounded men. It is different, as it has no weapon platform, which was replaced by a storage bin. The front of it is protected by an armored shield, while the side has a metal fence that can be used to store additional equipment and supplies.

Operational use

Following the successful testing of the prototype, a small 0-series was produced for the Serbian Army for further evaluation. These 12 vehicles were allocated to the 72. Бригаде за Специјалне Операције (English: 72nd Brigade for Special Operation). Ironically, this Brigade is also equipped with 4×4 BOV M16 Miloš Multi-Purpose combat vehicles. To differentiate these two, the RCUP Miloš is often referred to as Little Miloš. A few Miloš were used during military exercises, such as the Садејство 2020 and Муњевити Удар 2021.

For now, a small production run of some 12 vehicles is complete. Source:

The fate of the Miloš is not yet clear, but unofficially, it has been estimated that a production order of 50 to 100 of the V1 version are to be built. If this is true is yet to be seen. The price of the V1 version is noted to be €120,000 and the larger version €200,000.

While initially it was not intended for export, in 2022, the Miloš was presented to a delegation from the United Arab Emirates in Abu Dhabi. Despite the extremely warm climate, on demonstrations, the Miloš performed without any issues. If this demonstration bears any fruit for orders or modifications, only time will tell.


The Miloš is certainly a modern and capable remote control platform. Thanks to it, enemy infantry formations or positions can be engaged without the need to expose Serbian soldiers to unnecessary threats. How it will perform in the future and if a production order for more vehicles is ever achieved is yet to be seen.

Lazanski Armored Combat Vehicle 

Republic of Serbia (2021)
8×8 Infantry Fighting Vehicle – 1 Prototype Built

In recent years, the Serbian military industry has managed to develop and produce a series of 8×8 wheeled armored vehicles, including the Lazar series. A recent addition to the 8×8 family has been the Lazanski wheeled Armored Combat Vehicle (ACV), demonstrated for the first time in October 2021 at the Partner-2021 military exhibition in Belgrade.

According to some Serbian media news outlets, such as RTS, the prototype of the Lazanski 8×8 is a further development of the Lazar III project, but actually, it is a completely new vehicle that incorporates much better armor protection combined with stronger offensive armament, capable of engaging both ground and air targets. In addition, the vehicle retains the capability of transporting 10 fully armed soldiers. One of the most interesting features of the new ACV is the Russian remotely controlled ‘Kinzhal’ (Dagger) combat module.  At the moment, the vehicle is still in the early phases of development.

Given the Lazanski’s recent public display, the precise development history of this vehicle is not yet available to the public. According to the information revealed at the Partner-2021 exhibition, the Lazanski was developed by the well-known Serbian Yugoimport SDPR company, responsible for designing and manufacturing many modern armored vehicles in recent years. Yugoimport was founded back in 1949, with the intention of acquiring necessary military equipment for the JNA (Jugoslovenska Narodna Armija, Yugoslav People’s Army) from abroad.

After 1953, Yugoimport expanded the scope of its business to the export of domestic military equipment. One of its most successful exports has been the Lazar series. The Lazar (Series I to III) is an 8×8 wheeled armored vehicle designed to be able to transport 3 crew members and 9 soldiers. These were designed to be highly modular and equipped with different weapon outfits. First presented in 2008, they have seen service with the Serbian armed forces and have seen limited export success with countries such as Pakistan.

Initially, the Lazanski project was named after medieval Serbian Emperor Stefan Dušan Silni. It was renamed Lazanski to honor the late military analyst and diplomat Miroslav Lazanski, who died in August 2021.

While Lazanski’s overall design was made by the Yugoimport engineers, some elements, such as the remote-controlled turret, were imported from Russia. Sources do not mention why the Serbian engineers decided to use this weapon system. However, this is not the first example of  military-industrial cooperation between Russia and Serbia. Earlier in 2021, Yugoimport sold a batch of Lazar 3 wheeled ACVs armed with Russian-made BPPU turrets to Turkmenistan.

Given the general close cooperation between the Russian and Serbian arms industry, this also should not come as a surprise, as both sides benefit from this mutually reinforcing collaboration. The Serbian Army could receive a new high-tech weapon system without the need to invest in research and development. At the same time, the Russian side could enter new emerging markets thanks to the Serbian brand-new wheeled platform and the fact that the Serbian arms industry is not under the threat of sanctions.

The price of the Lazanski ACV might be between $2 and $2.5 million, depending on the armament and configuration, according to certain unverified sources. The export prospects are unclear at this point, however, it is possible that Serbia might enter new markets with the help of Rosoboronexport, the sole state intermediary agency for Russia’s exports/imports of defense-related and dual-use products, technologies, and services. However, with the sanctions imposed on the Russian Federation following the 2022 invasion of Ukraine, it is unclear how this could affect the Lazanki.


Not much is known about the design and performance, as the vehicle is in its early development phase. However, some limited specifications have been revealed at the Partner-2021 exhibition. According to official sources, Serbia expects to finish trials of the platform by the end of 2022. While the Lazanski shares some similarities with the Lazar 3, it also incorporates a number of improvements.

Engine and the Chassis

The Lazanski ACV hull measures 8 m long, 3.2 m wide, and 2.6 m high. Overall height including the turret is 3.6 m. Since the platform could be equipped with modular armor protection, the weight would vary. The lightly armored version weighs 26 tonnes, while the weight of the Lazanski ACV fitted with heavy armor could reach up to 36 tonnes. The ACV does not have amphibious capabilities and features a hydro-pneumatic suspension.

The Lazanski is powered by a 711 hp Caterpillar C13 engine connected to a six-speed Allison 4000SP automatic transmission. The engine itself is placed on the front right side of the vehicle. The design of the running gear also incorporates driving axles produced by the Finnish company SISU, and a transfer gearbox by Katsu.

The Russian military blog bmpd, which is part of the CAST think-tank, points out that the automotive part of the Lazanski is very similar to Finnish Patria AMV XP.

Crew, Hull, and Internal Layout 

The Lazanski’s hull is welded, made of armored steel, and has a relatively simple shape featuring flat rear and sides and sloping-down frontal plate. The internal layout is typical for basically all modern armored vehicles of this type, with an engine compartment at the front-right, driver’s compartment at the front-left next to the engine, the combat compartment in the middle, and, finally, the infantry dismount compartment at the back of the vehicle.

The engine is fully enclosed but has a few access hatches with ventilation grilles that the crew can use for maintenance.

Crew members can access their positions through the two hatches on the top of the hull or through the passage between the fighting compartment and the infantry dismount compartment. The crew could use the same passage as an emergency exit, allowing the crew to leave the vehicle through the rear ramp in case the hatches at the front are damaged or under enemy fire. Each crew hatch is provided with three vision blocks. Some elements of the hull are covered by an anti-slip coating. Dismounts are supposed to leave the vehicle by using the rear hydraulic ramp.

In order to fully operate the Lazanski, a crew of three is needed. This includes the commander, gunner, and driver. The driver is located on the front left side, with the commander’s and the gunner’s seats placed behind. To the rear is a large infantry dismount compartment where 10 fully armed soldiers can be stationed in shock-mitigating seats. The soldiers’ seats are divided into rows of five seats on each side, which are positioned opposite each other.

In order to provide the crew with an excellent field of view, the Lazanski is equipped with six surveillance infrared cameras which provide a full 360° field of vision. In addition, the driver has two mirrors, one placed on each side of the vehicle.

According to bmpd, the Lazanski is also equipped with several subsystems, such as an air conditioning unit, intercom, NBC protection, a navigation system, and an automated battle management system.

While other Serbian designs, such as the Lazar, have side doors and firing ports for dismounts, the Lazanski does not.

Turret and Armament

The Lazanski is armed with the ‘Kinzhal’ Russian-made remotely operated and controlled combat module.

The ‘Kinzhal’ (Dagger) is a further development of the AU-220M ‘Baikal’ RCWS. Both modules were developed by CRI Burevestnik, which is part of Uralvagonzavod.

The standard armament of the ‘Kinzhal’ consists of a 57 mm 2A91 (BM-57) autocannon with eighty ready-to-fire 57 x 348 mm rounds in the internal storage. The secondary armament consists of the coaxial 7.62 mm PKTM machine gun with 1,000 stored rounds and smoke dischargers. Additionally, ‘Kinzhal’ can be fitted with two 9M120 Ataka-M ATGMs. However, the exhibited prototype had no ATGMs installed.

Kinzhal’ includes a sophisticated fire control system (FCS) with day and night capability and a panoramic sight, but the exact specifications are not known. Typical ammunition load for the 2A91 autocannon consists of HE-T (UOR-281U) and AP-T (UBR-281U) rounds. Also, the manufacturer plans to develop a 57 mm programmable HE round and guided round for use against aerial targets, such as helicopters and UAVs.

The 2A91 57 mm autocannon originates from the S-60 autocannon used on the ZSU-57-2. The 2A91 retains the capability to use older rounds.

According to the manufacturer’s information, the turret weighs 3,850 kg, including elements installed inside the hull. Some sources, such as the Russian bmpd, say that the combat station fitted on the prototype exhibited at the Partner-2021 weighs only 3,600 kg.

This difference probably appeared because the turret was installed without some elements, such as Ataka ATGM launchers, or the prototype was equipped with a full-scale mock-up of the ‘Kinzhal’ RCWS.

Since the Lazanski’s design is modular, the vehicle could be quite easily fitted with a wide variety of turrets and weapon stations of either domestic or foreign origin. For example, Serbian news outlets mentioned that the idea to arm Lazanski with a Turkish-made MIZRAK-30 turret is under consideration.

Armor and Protection

The hull of the prototype is constructed from steel with additional ceramic armor. According to the manufacturer, the ballistic protection of the frontal arc reaches Level 5 STANAG 4569A, meaning it can withstand 25 mm projectiles from 500 m and 155 mm shell splinters. The ballistic protection of the sides and rear reaches STANAG 4569A Level 3, and is able to withstand 7.62 mm AP bullets from any distance. According to the designers, the effectiveness of this armor was examined and tested in Germany and Israel.

In addition, Yugoimport is developing an appliqué armor kit able to raise the ballistic protection to STANAG 4569A Level 6, which means the ability to withstand 30 mm APDS rounds from 500 m distance.

In terms of blast protection, the Lazanski has a V-shaped bottom and can sustain blasts of up to 10 kg of explosives (STANAG 4569B Level 4a/b).

Additionally, the Lazanski, in the configuration demonstrated at the Partner-2021 exhibition, was provided with several smoke dischargers for self-protection.

Future and Conclusion

The Lazanski is certainly an interesting design coming out of the relatively small Serbian military industry. According to Serbian media and its constructor, the Lazanski is a high-tech modern armored vehicle with huge military potential in domestic use or as an export product. Besides it, the Serbian military industry achieved some export success with the Lazar III and Nora series of self-propelled guns.

Given its experimental nature, it is hard to predict its fate at this point. However, it is possible to make several assumptions.

Firstly, the ACV is not in its final shape, and the development of the Russian Bumerang platform, which was constantly delayed, may offer a cautionary tale on how the development might take more time than is anticipated. Obviously, many changes and improvements are to be expected in the near future. These would probably be mainly focused on increasing its survivability and various additional equipment.

Secondly, given that the platform is designed on a modular basis, we can expect that various variants of the Lazanski will appear. In the future, the Lazanski might start a whole new family of combat and auxiliary armored vehicles, including APCs, ARVs, self-propelled artillery systems, C2, or CBRN variants, but this remains to be seen.

Modern Serbian Armor

Samohodna Haubica 122 D-30/04 SORA

Republic of Serbia (2004)
Self-Propelled Gun – 1 to 2 Prototypes Built

Following the disintegration of the Socialist Federal Republic of Yugoslavia in the early 90s, the new Federal Republic of Yugoslavia (in 2003, its name was changed to Serbia and Montenegro and finally, in 2006, Serbia became an independent state) inherited a relatively huge stock of various armament, equipment and weapons. One of these was the Soviet 122 mm D-30 and the domestically modified D-30J (with improved ammunition) howitzer. As the Serbian Army lacked a more modern self-propelled artillery (beside the aging 2S1 Gvozdika), in 2004, an attempt was made to develop such a vehicle using a military truck chassis and arming it with a 122 mm D-30J gun.

During 2004, the military leadership of the Army of Serbia and Montenegro discussed the possibility of improving the performance of the 122 mm D-30J howitzer. This was, in essence, just a Soviet D-30 howitzer that was imported during the 70s. The main difference was the use of improved ammunition with stronger propellant charge, which increased the overall firing range of the howitzer. The military decided to develop a brand new self-propelled artillery vehicle equipped with this howitzer. This vehicle was to act as a mobile fire support element of infantry and armored brigades. Its main mission was to saturate enemy positions with artillery fire before changing position to avoid counter fire. Great emphasis was thus placed on good mobility and sufficient firepower.

The development of such vehicles could basically go in two directions. Either a fully tracked vehicle or a truck wheel chassis. Due to factors including cost, the possibility of using already existing production capabilities, and reducing development time, the officials of the Army of Serbia and Montenegro decided to proceed with the second option.

While the Serbian Army used the 2S1 Gvozdika, it was an old design that was becoming obsolete, so a new vehicle equipped with the 122 mm D-30J howitzer was needed to replace it. Source: Srpskioklop


The official designation for this vehicle was Samohodna Haubica (self-propelled howitzer) 122 D-30/04 SORA (Serbian.- Самоходна Хаубица СОРА). In many sources, it is just mentioned as SORA (SORA-122 or 122 mm SORA are also used). This article will use this designation for the sake of simplicity.

Developing process

The job for designing such a vehicle was given to the Vojno Tehnički Institut VTI (Војно Технички Институт). Work on the construction of the first operational prototype was given to the ‘14 Октобар’ (14th October) factory from Kruševac. The VTI decided to go with a simpler solution, possibly in hope of reducing the overall cost and time. The new vehicle consisted of a standard military truck with its cargo bay replaced with a new firing platform with the 122 mm D-30J howitzer. Initially, a KAMAZ truck was to be used as the main chassis, but this was changed to the FAP2026 BS/AB, which was already in use.

In 2006, after a referendum, Montenegro became an independent state, and the development of the SORA vehicle was left to the Serbian Army. During 2006, there were a number of changes in the leadership of this project (due to the retirement of people involved in it). The project was given to Colonel Novak Mitrović. He was chosen mostly due to his experience with designing such vehicles. Besides the SORA, Colonel Mitrović was also involved with the design work of another self-propelled project, the 152 mm NORA-B. Colonel Mitrović would be replaced as the head of the SORA project by Lieutenant Colonel Srboljub Ilić. He had worked earlier on the 100 mm TOPAZ anti-tank gun (which was based on the D-30J). He too would be replaced by Mihajlo Trailović in 2007 due to retirement.

In 2008, at the 14th October factory, the preparations for the final assembly of the SORA began. However, there were some issues with the design of the firing platform. For this reason, another factory, the Tehnički Remonti Zavod Čačak (TRZ Čačak) – Технички Ремонти Завод Чачак was included in the project. Its engineers managed to design the modified D-30J mounting, which they successfully placed on the FAP2026 BS/AB chassis.

The SORA vehicle was then sent back to the 14th October factory, where it was fully completed and given to the Army for field testing. The testing and evaluation of the vehicle proved to be generally positive after firing trials held in the Nikincima army test site. In 2011, it was presented to potential foreign buyers at the ‘Partner 2011’ (Партнер) Arms Fair held in the Serbian capital, Belgrade. The first prototype failed to gain any foreign interest, nor did the Serbian Army adopt it. Despite this, work on improving its performance was carried on.

The improved version

Following the completion of the first prototype and its failure to gain any military contract, attempts were made to increase its overall performance. Sources are not clear if the second vehicle was just a modified first prototype or a completely new vehicle. The second prototype incorporated several new improvements which included: an automatic loading system, an improved fire control system, reducing the numbers of crew members, increasing ammunition load, and adding a close defense machine gun. It was presented for the first time for potential buyers at the ‘Partner 2013’ Arms Fair.

Technical Characteristics


The basis of this vehicle was the FAP2026 BS/AB 6×6 all-terrain wheeled truck. This was a vehicle domestically developed and built by the FAP (Fabrika Automobila Priboj) factory beginning in the late 1970s. It was primarily designed to act as a towing vehicle for a number of artillery pieces. It could also be used to transport troops and materials, with up to 6 tonnes capacity. It was powered by a German Mercedes OM 402 engine giving 188 kW @ 2500 rpm. The maximum speed of this truck was 80 km/h and the operational range was 600 km.

For the SORA, the FAP2026 truck chassis had to be reinforced and strengthened to be able to withstand the firing recoil of the main gun. The weight of this new vehicle was 18 tonnes and the operational range was reduced to 500 km. The maximum speed was 80 km/h, dropping down cross country to 20 km/h. A spare wheel was positioned to the vehicle’s rear. To use this wheel, a mechanical crane was added, which, when activated, lowered the wheel to the ground.

Main weapon

The main weapon chosen for this vehicle was the 122 mm D-30J howitzer. This weapon was originally designed during the early ’60s in the Soviet Union. It was a somewhat unusual howitzer, mostly due to the design of its trail legs that, when fully deployed, enabled the gun to have a 360° traverse. During deployment, the rails of this howitzer are split into three different smaller legs, evenly separated. The wheels would be then raised from the ground up, thus creating a stable platform for the gun for firing in any direction. During transport, these three legs would be connected together and placed under the barrel. On the muzzle brake was a towing hook.

The original Soviet 122 mm D-30, with its nearly 22 kg round, had a range of some 15.4 km. The Yugoslav modified howitzer had a slightly longer range thanks to improved ammunition and larger propellant charge, reaching up to 17.5 km.

The Serbian 122 mm D-30J. Source: Wiki

To make room for the D-30J howitzer and its mounting on the truck chassis, the rear positioned storage bin was removed. Instead of it, a new firing platform was placed to the rear. The howitzer, without its wheels and trail legs, was placed on a new round-shaped mount. Below this mount, a hydraulically operated support leg was to be lowered during firing. When ready for the firing mission, the main weapon was rotated to the rear. Despite the appearance of possessing an all-around firing arc, this was not the case.

During 2005, while still in the development phase, a number of experiments were done in order to test the durability of the front driver’s cabin during the firing of the main weapon to the front. As the tests showed that it lacked proper durability and general stability, instead the D-30J howitzer was pointed to the rear to avoid any damage to the driver cabin. Elevation of the D-30J howitzer was -5° to 70°, and the traverse was 25° in both directions. To help with absorbing recoil and providing a stable firing platform, two hydraulically operated supporting legs would be placed to the ground. When on the move, the D-30J howitzer was to be repositioned to the front and held in place at a 10° angle by a travel lock placed above the ammunition and crew housing. The SORA has an ammunition load of 24 rounds.

The SORA-122 D-30J howitzer had to be manually loaded and fired, which, given the lack of crew protection, made it quite vulnerable to enemy return fire. For this reason, following the completion of the first prototype, a new project was started with the aim of equipping the SORA with a more modern automatic loading and improved fire control systems. The new automatic loading system consisted of two round-shaped drums placed on both sides of the main gun. These were used to store six rounds of ammunition (placed in the right drum) together with six propellant charges (in the left drum). When these were all fired, they had to be manually reloaded.

When moving to the designated area of attack, this new configuration required some 3.5 minutes to deploy, fire six rounds, and disengage. Around 90 seconds were needed for the vehicle to be combat-ready for firing. The firing cycle of all six rounds was 1 minute. An additional minute was needed for the vehicle to prepare for moving again. The speed for redeployment after firing was desired to be as short as possible. It was estimated that enemy radar detectors would need at least 2 minutes to detect the SORA’s firing position after it fired, by which time it had already changed position to a new location. The whole process of deploying and redeploying was completely automated and easy to use.

The second prototype had a new automatic loading system. It consists of two round-shaped drums placed on both sides of the main gun. Six rounds were placed in the right drum, while six propellant charges were put into the left drum. Source:

On the improved prototype, the firing of the main weapon could effectively be done either from the vehicle itself or from a distance of 150 to 200 m (wired or wireless) from a mobile computer. The D-30J firing trigger was activated by a pneumatic cylinder. If, for some reason (malfunction or combat damage), the firing trigger failed, it could be operated manually by the crew members.

The new total ammunition load of the self-propelled guns would be 40 rounds, mainly located in the ammunition racks in the back of the cabin. The SORA could fire a number of domestically developed ammunition. These included the TF-462 with a range of 15.3 km, TF PD UD M10 with a range of 18.5 km, and the TF PD GG M10 with the greatest range, up to 21.5 km. The elevation and traverse were unchanged in comparison to the first prototype. The elevation and traverse speed ranged from 0.1 to 5 degrees per second.

For crew protection, beside their personal weapons, a 7.62 mm M84 machine gun was placed on top of the driver’s cabin. To use the machine gun, the crew were provided with a hatch.


The first prototype had at least four to five crew members (the sources do not specify the precise number). These were the commander, the driver, the gun operator, and loaders (one or more). The crew were seated inside the front cabin and in the rear positioned superstructure, which had two side doors.

The second prototype had only three crew members. It consisted of a commander, a driver, and a gun operator. While the sources do not specify it, one (or more) of these men also had to act as loaders for the drum magazine. In comparison to the previous model, the new one did not have the rear positioned crew compartment. This was instead replaced with added ammunition storage bins.


The SORA was not provided with any armor protection, neither for the front driver cabin nor for the gun operators (besides the small gun shield on the first prototype). The main reason for this was to reduce the cost and weight as much as possible. While the use of a protective armored cabin for the gun operators was considered, it was not adopted.

Fate of the project

The overall situation of the SORA within the Serbian Army is unclear. While, in the media and according to many statements of the Ministry of Defense over the years, one gets the impression that the SORA would be adopted, the project is nearly two decades old and still in the prototype phase. In addition, very recently, the Serbian Army stated that it is interested in upgrading its old 2S1 Gvozdika vehicles. The SORA also failed to gain any foreign interest despite its low price and simplicity. The Serbian Army appears to be focusing more attention in developing and introducing into service the much larger NORA B-52 and another 122 mm armed SOKO self-propelled artillery vehicle. Based on these factors, it is unlikely that it will be adopted for service within the Serbian Army in the near future, if ever.


The SORA is designed as a cheap and quick solution to the Serbian army’s lack of more modern self-propelled artillery. Despite achieving these goals, for unknown reasons, it is still not yet adopted for service. Despite its final fate, it provided the Serbian engineers with a good deal of experience in designing more modern vehicles.

Republic of Serbia (2009)
Experimental Modular Robotic System – At Least 1 Prototype Built

In the last few decades, all of the major armies around the world have shown an interest in the development of remote-controlled devices. These are meant to perform various tasks and intended to supplement or even replace human soldiers in dangerous situations, thus reducing the risk to human life. The tasks of these remote-controlled devices are many, ranging from reconnaissance, target identification, ammunition and other equipment resupply, transport, engaging and destroying designated targets, etc.

The Serbian Army, in a desire to follow international arms development trends in unmanned ground vehicles (UGV), began developing a series of its own vehicles. One of these project was the short range anti-tank system named simply Милица (Eng: Milica -a Serbian female name). It was, in essence, a small remotely-controlled tracked vehicle armed with two anti-tank launchers.

Jugoimport (Југоимпорт СДПР Ј.П) was founded back in 1949, with the intention of acquiring necessary military equipment for abroad for the JNA (Jugoslovenska Narodna Armija, Yugoslav People’s Army). After 1953, Jugoimport expanded the scope of its business to the export of domestic military equipment. In 2006, Jugoimport was reorganized and became a Serbian state-owned public enterprise.

During the following years, Jugoimport would continue to work on improving the performance of a number of older projects developed during pre-Civil War Yugoslavia. It also began a series of experiments to develop new technologies and weapon systems, including self-propelled artillery vehicles, armored cars, APCs, and multiple launch rocket systems etc.

During the late 2000s, Jugoimport was also involved in the development of a number of remote-controlled systems meant to perform different tasks, ranging from reconnaissance to the anti-tank. These included the Vrabac (Sparrow) unmanned aircraft, APOS – automatizovani protiv tenkovski sistem (Eng: automated anti-tank system), DALOS – daljinski upravljanu laku modularnu osmatračko-borbenu stanicu (Eng: remotely controlled light modular observation-combat station), and the Milica – modularni robotički sistem (Eng: Modular Robotic System).

Milica was primarily intended to provide infantry with a remotely controlled anti-armor close support system that could engage modern MBTs (main battle tanks). It could also be used to engage and destroy enemy firing positions and fortifications. The Milica system was intended to be fully modular, which meant it could be adapted to fulfill various combat roles, but also secondary non-combat duties. Other roles included helping infantry with gathering intelligence, monitoring and observing areas that were not yet fully secured, transporting spare equipment, ammunition, and even transporting wounded soldiers.

Not much is listed in the sources about its development history. It was presented for the first time to the public at the military Partner 2009 fair held in the Serbian capital, Belgrade.


Inspiration for the Milica’s overall design (like the hull, superstructure, and suspension) was taken directly from the BVP M-80 infantry fighting vehicle. Back in the 1960s, the JNA placed a request for a fully protected infantry fighting vehicle. From this, the BVP M-60 was developed. As it proved to be unsatisfactory, a new model, the BVP M-80, was therefore developed to replace it. It was a large improvement in contrast to the earlier model and was provided with a fully rotating turret and anti-tank rockets. From 1976 to 1988, around 658 M-80s were built. Despite their old age, a number of these vehicles are still in use with the Serbian Army.

The BVP M-80 infantry fighting vehicle served as the basis for the Milica’s overall design shape. Source:


While there is limited information on its interior, based on the available pictures, it can be seen that the hull was divided into a few sections. The transmission was placed in the front of the hull, followed by the electric motor. The batteries and other equipment needed for controlling and powering the main weapon system were stored to the rear of the vehicle.


The Milica’s superstructure was taken more or less from the M-80. It had a very simple design, with a highly angled front plate, slightly less angled sides, and flat rear. There were a number of rectangular-shaped hatches placed in the superstructure to provide easy access to the different components stored inside.

In the front angled glacis, there was a hatch for access to the engine and the transmission. Three hatches were placed on top of the superstructure, with two in the front and to the rear. The last hatch was placed at the rear. Next to it, there was a round-shaped plug, possibly used for powering the main motor and system batteries. All of these hatches were held in place by simple screws, so removing them was quite easy.

The Milica’s superstructure was built using simple welded steel plates. The thickness of these plates is unknown, but probably only enough to provide protection from small-caliber weapons. Its greatest protection was its relatively small size. The Milica was 1.9 m long (1.72 m without the main armament), 0.77 m wide, and had a height of 0.77 m.

The suspension was another element that is quite similar to that of the M-80, albeit with one more roadwheel. The suspension consisted of six small road wheels, which were independently suspended with torsion support units. In addition, there was a front-drive sprocket, rear idler, and three return rollers.

The sources do not provide information about the engine type or its power output. What is known is that an electrical motor was used. With a weight of 250 kg, its maximum speed is only 3 km/h. The effective operational autonomy was noted to be 2 to 4 hours. It can climb a 30° slope and is supposed to possess amphibious capabilities.


An ‘H’ shaped metal firing platform was bolted to the superstructure top. This is then used to house either the two 9 cm M79 OSA or a single 12 cm M91 anti-tank rocket launcher. The 9 cm M79 OSA anti-tank rocket launcher is in service with the Serbian Army and its purpose is to engage enemy armor and fortified positions. Its effective range is 350 m and the maximum effective range is 650 m. Armor penetration power is 400 mm of rolled homogeneous armor.

The elevation of the Milica weapon platform was -20° to +50° and the traverse was 350° (it could not rotate a full circle). Elevation speed was 3°/s, while the traverse speed was slightly faster, at 6°/s. The two launchers were fired independently. Once both tubes were fired, the Milica had to be driven back to a safe position to be reloaded.

The Milica is mostly seen armed with the two 9 cm M79 OSA anti-tank launchers but, if needed, another weapon system could simply replace these. Source:

Depending on the combat requirement, the Milica could be armed with the 12 cm M91 rocket launcher for improved anti-tank capabilities. This is a disposable light shoulder-launched rocket launcher that is in the service of the Serbian Army. The M91 consists of two components, the launcher, and the shaped charge rocket projectile. The shaped charge warhead, containing an explosive filling of phlegmatized octagen and a contact-type electric superquick fuze. The M91’s main purpose is to engage modern MBTs at ranges up to 250 m. Its penetration power against rolled homogeneous armor is around 800 mm. Secondary targets, like fortified enemy positions, could be engaged at ranges up to 400 m. Currently, there is no picture of Milica being armed with this weapon.

While these two were intended to be the Milica’s primary armament, other weapon systems, depending on the field requirement, could be used instead. These options ranged from different types of machine guns, grenade launchers, to possibly even small-caliber cannons.

Control and optics

The Milica was a wireless remote-controlled system that was operated from a concealed command post. The effective wireless control range is around 500 meters. The command unit of the vehicle consists of a control system with telecommunication modules. In addition, there is also a laptop computer which is used for choosing the camera mode and for finding targets. The Milica’s movement and weapon system were controlled by a console with an alphanumeric monitor. The sources do not mention the precise number of operators that were needed to properly control the Milica.

For directly observing surroundings and possible targets, the Milica was provided with an all-weather, day and night, black and white IP (internet protocol) surveillance camera. This camera also possesses high sensitivity electrical and optical zoom. The camera itself was placed in a protective housing above the two rocket launchers.

Operational use and fate

When the prototype was completed, it was tested at the Nikinci experimental military test range in November 2009. It underwent a number of firing tests and, while the sources do not go into much detail regarding these tests, they note that the Milica performed satisfactorily.

As mentioned earlier, it was presented for the first time to the public in 2009. In the following year, it was still presented at the military Parner fair held in Belgrade, in the hope of gaining some foreign interest.

It appears that the Milica was mostly used as an exhibit for potential foreign buyers after 2009. Source:

It appears that the Milica was not adopted for service within Serbia nor anywhere else in the world. In recent years, the Serbian Army appears to have adopted (in limited numbers) another similar system. This is named the Miloš Remote Control Unmanned Platform (Милош ДУБП – Даљински Управљива Безпосадна Платформа). The precise number of Milica built beside the one prototype is not known.

The Milica was one of the first Modular Robotic Systems developed by the Serbian arms industry. It offered an alternative way of supporting infantry operations, minimizing the risk to the soldiers operating it. While it was not adopted for service, it provided Serbian engineers with valuable experience in designing and building such systems. This would lead to the development of newer systems that entered limited service in recent years.

Cold War Yugoslav Tanks Has Own Video Modern Serbian Armor


Socialist Federal Republic of Yugoslavia and Successor States (1985-Present)
Main Battle Tank – 650 Built

Symbol of Brotherhood and Unity

Development and production of the M-84 Main Battle Tank (MBT) by the Socialist Federal Republic of Yugoslavia perfectly symbolized their national slogan, Brotherhood and Unity, just a decade before the country fell apart. It combined the economies and production capacities of six Yugoslav multi-ethnic republics to produce what will become their national pride. Considered one of the most ambitious projects undertaken by the Yugoslav industry, it proved how complex and demanding tank production can be even for medium-sized countries.

After the Second World War, Yugoslavia operated a wide variety of Axis and Allied armored vehicles. Two armored brigades consisted of captured German Panzer IIs, Panzer IIIs and Panzer IVs, along with American M3 Stuarts and around five Soviet T-34-76s captured from German Anti-Partisan units. Italian L6/40, M13/40, M14/41, and M15/42 tanks were also captured during the war and kept in limited service. Based on an agreement with the Soviet Union, 308 T-34-85 tanks and 52 SU-76M self-propelled guns arrived in 1947. This was just before the Tito-Stalin Split of 1948, after which the relations with the Soviets became distant.

Two years later, an attempt to produce an unlicensed copy of the T-34-85, known as the Type A, proved unsuccessful. Production was slow and required skilled workers due to a lack of blueprints and standardized parts, which resulted in just five prototypes being built before the programme was cancelled. Following an agreement, this time with the United States, between 1951 and 1957, Yugoslavia received 599 M4A3 Shermans and 319 M47 Patton tanks, 140 M18 Hellcat and 399 M36 Jackson tank destroyers as military aid part of the Mutual Defense Assistance Program, along with many other kinds of military vehicles.

Without the means to produce spare parts for the newly acquired tanks, maintaining them became a rising problem. In the meantime, the relationship with the USSR started to improve after Stalin’s death. A Yugoslav Army delegation visited the Soviet military academy and attended a military exercise, at which they had a chance to see the new T-54 tanks in action. During the next 25 years and across several contracts, the Yugoslav People’s Army (JNA) acquired 140 T-54s and over 1,600 T-55s. In the late sixties, JNA military officials realized that many of the older T-55s needed to be completely replaced by new tanks. It was also becoming apparent that the procurement of a tank more modern than the T-55 could not be postponed any longer.

In the early seventies, the T-72 appeared on the world stage and captured the interest of Yugoslav military experts. It was available for sale, but obtaining a license for its production was impossible during the first few years, even for Warsaw Pact countries, let alone Yugoslavia. In 1978, after Yugoslav military officials had seen the T-72 during a presentation near Moscow, a decision was made to purchase the license. The Soviets quickly rejected the request, with an explanation that Yugoslavia was not able to produce such a vehicle due to its complexity. Shortly after, President Tito visited the USSR and, even with the strong objection of the Soviet Ministry of Defense, he managed to convince Leonid Brezhnev, the General Secretary of the Communist Party, to sell the license to the Yugoslavs. The price was 39 million dollars ($162 million in 2020 values), with the license expiring after 10 years or 1,000 produced tanks. The agreement also stated that Yugoslavia could not sell, modify, or co-produce the tank with other countries without the USSR’s approval.

Before the beginning of production, obtaining various machines and tools proved to be very difficult. For example, in order to reduce the weight, the tank’s main wheels were made out of aluminium alloy. The production process was very complex, requiring a 30,000-tonne press, additional smaller presses, and a special furnace. At that time, there was only one press of similar characteristics in the whole of Europe. The production was a real endeavor. Over 200 companies from all six of Yugoslavia’s republics were contracted to produce different parts and subsystems, along with the Djuro Djakovic factory, responsible for the final assembly.

The prototype, designated T-72MJ, was finished in April 1983, followed by 10 test vehicles in 1984. Serial production started in 1985 and the vehicle received its new designation: M-84. Some of the factories involved in the production and their products were:

  • “Djuro Djakovic” – Slavonski Brod – Final assembly
  • “Famos” – Pale (Bosnia and Herzegovina) – Engine
  • “Iskra” -Ljubljana (Slovenia) – Laser rangefinder and electronic parts
  • “Zrak” – Sarajevo (Bosnia and Herzegovina) – Optics
  • “Slovenske Zelezarne” – Ravni (Slovenia)- steel / armor
  • “Prvi Partizan” – Uzice (Serbia) – ammunition
  • “Pretis” – Vogosca (Bosnia and Herzegovina) – ammunition
  • “Prva petoletka” – Trstenik (Serbia) – hydraulics
  • “21 Maj” – Rakovica (Serbia) – manual turret traverse system
  • “Bratstvo” – Travnik (Bosnia and Herzegovina) – cannon
  • “Metalski zavodi Tito” – Skoplje (Macedonia, today North Macedonia) – parts of the transmission
  • “Rudi Cajevec” – Banja Luka (Bosnia and Herzegovina) – electronics and Fire Control System
  • “Sever” – Subotica (Serbia) – autoloader mechanism
  • “Industrija lezajeva Kotor” – Kotor (Montenegro) – bearings



For its time, the M-84 was a fairly modern tank with good protection, thanks to its composite armor. The upper front plate had a slope of 68 degrees and consisted of an 80 mm rolled homogeneous (RHA) steel plate followed by 105 mm of glass-reinforced plastic called textolite, backed by a 20 mm steel plate. This armor arrangement equated to around 350 mm of RHA against Armor-Piercing Fin-Stabilized Discarding Sabot (APFSDS) and around 450 mm against High Explosive Anti-Tank (HEAT) projectiles. The lower front plate was at a 60-degree angle with a thickness of 80 mm. Some additional 20 mm of protection was in the form of a mounted dozer blade and it also enabled the tank to dig a cover for itself in a short amount of time. The hull sides were vertical and had a thickness of 80 mm at the crew compartment and 70 mm at the engine-transmission compartment, while the backplate was 40 mm thick and inclined at 30 degrees. The floor and engine deck were 20 mm thick. Rubber side skirts were also mounted to reduce the amount of dust kicked up by the tank when moving.

While the hull had a welded construction, the turret was cast. Due to its variable thickness, it provided approximately 280-380 mm of RHA protection. This early armor layout was equivalent to the T-72M and had no composite material in the turret.

The M-84’s low silhouette also contributed to the overall protection. The tank featured Nuclear Biological Chemical (NBC) protection equipment and two ways of deploying a smokescreen. The first was using 12 smoke dischargers on the turret front. These launched grenades 150 m in front of the tank, making a smokescreen either 20 m or 100 m wide which lasted 4-5 minutes. The second was through the use of an engine smoke generation system. The system sprayed fuel into the hot exhaust to create a trail of white smoke behind the tank. The M-84 was also equipped with an automatic fire extinguisher system.

The M-84 tank was armed with a smoothbore 2A46 125 mm main gun with a thermal sleeve – the same gun as on the T-72 Soviet MBT. It could fire 3BM9 and 3BM12 APFSDS with 350 mm of penetration at 90 degrees at 2 km, 3BK14M HEAT-FS with 500 mm of penetration at 90 degrees and High Explosive Fragmentation (HE-FRAG) ammunition.

The gunner also had a 7.62 mm PKT coaxial machine gun at his disposal, while the commander operated a 12.7 mm NSVT anti-aircraft machine gun. The main difference between the T-72 and the M-84 was in the Fire Control System (FCS). The new FCS was developed domestically and had better capabilities compared to the one used in the T-72M. It was named SUV M-84 and was claimed to be comparable to the best fire control systems in the world at that time. The FCS main module was the DNNS-2 gunner’s sight with an integrated laser rangefinder. This device was installed on the left side of the turret, in front of the gunner’s hatch. It had two different magnifications, 3x and 7x, while the night channel had an 8.5x magnification. The night channel had a second-generation image intensifier. The gunner also had a direct vision periscope. The commander was equipped with a DNKS-2 binocular periscope with a 360-degree view and image intensifier for night operation. With a press of a button, he could slew the turret to the target’s direction or engage it himself. There were four additional periscopes at his disposal. Another component of SUV M-84 was the meteorological sensor located on the front of the turret roof, which measured wind speed, ambient temperature, and atmospheric pressure. The FCS used this information, combined with additional data such as distance to the target, powder charge temperature, the longitudinal and horizontal tilt angle, and the tank’s movement speed to ensure high first-hit probability while on the move or when stationary. While the gunner tracked a moving target, the SUV M-84 automatically applied lead by calculating the target’s angular velocity.

Instead of a human loader, the tank had an electro-mechanical autoloader for the main gun. With one crew member less, the turret could be made smaller and better armored for the same weight. The autoloader was located under the turret, on the tank’s floor. It held 22 rounds in its rotating transporter, commonly called a carousel, while additional 20 rounds were stored in the crew compartment. The autoloader had a fixed loading angle, which meant that the gun needed to be elevated to +3 degrees in order to line up the breech with the ammo rammer. Since the gunner’s sight was independently stabilized and not slaved to the gun, the sight remained on target during the loading process. The rate of fire was 8 rounds a minute. Contrary to popular belief, the carousel was well protected from shrapnel in case of a turret penetration. A door, through which the ammunition passed, closed after the loading process, protecting the ammunition. Though the ammunition in the carousel might be safe from most penetrations, the ammunition in the crew compartment could still ignite. Studies after the 1991 Gulf War showed that most of the catastrophic explosions of Iraqi T-72’s were caused by ammunition outside the carousel getting hit.

The M-84 was powered by the V46-6, a 38.8 liter V12 multifuel engine delivering 780 horsepower. It could use diesel, low octane gasoline, or kerosene. The engine was reliable and gave the tank adequate mobility with a 19 hp/tonne ratio. The manual transmission had 7 forward and 1 reverse gear. The only downside was a painfully slow reverse of just 4 km/h. which plagued almost all tanks built on the T-72 platform. Although useful while maneuvering and parking in a non-combat environment, it seriously hampered the ability to quickly reverse out of trouble. The tank had a fuel capacity of 1,600 l (with additional fuel drums at the back) and an operational range of 700 km on the road and around 460 km off-road. Depending on the terrain, fuel consumption went from 230 to 350 l per 100 km. The tank had a torsion bar suspension with double shock absorbers on the first, second, and sixth pairs of doubled road wheels. The tracks, 580 mm wide, were supported by 3 return rollers. The sprocket wheel was at the back. The system could span a 2.8 m trench, climb an 85 cm wall, and ford 1.2 m without preparation. With full preparation, it could ford water obstacles 5 m deep and 1,000 m wide.

Production and variants

In total, around 650 tanks of all variants were produced. The most numerous variant was the basic M-84 with 370 vehicles made between 1984 and 1987.



In 1987, a new variant of the M-84 started production and received the designation M-84A. While firepower remained the same, armor protection and mobility were substantially improved. The upper frontal plate had a different laminate layout and consisted of a thin 16 mm high hardness steel plate welded to a 60 mm rolled homogenous plate, followed by 105 mm of textolite backed by a 50 mm plate. While the basic M-84 had a simple cast steel turret, the M-84A’s turret had a cavity filled with Quartz sand mixed with an adhesive. The thickness of this insert was 130 mm. The tank’s new armor layout was claimed to be effective against contemporary NATO 105 mm projectiles. Mobility was improved by replacing the old 780 hp engine with a 1000 hp V-46TK. The new engine gave the M-84A an excellent power-to-weight ratio of 24 hp/tonne. That was enough to propel the 41.5-tonne tank to a respectable top speed of 65 km/h. Around 100 vehicles were assembled until the end of production in 1992.

The M-84AB/ABK was an export variant made for Kuwait. The company in charge of export and shipment was Yugoimport SDPR. It impressed the Kuwaitis after it won a desert trial against the M1A1 Abrams. It proved more reliable and finished the 102 km course without breakdowns, while the Abrams was not able to finish due to a fuel system malfunction. Later, Yugoslav mechanics demonstrated engine removal, complete disassembly, and reassembly in the field. The Kuwaitis were sold and made an order of 200 M-84AB and 15 M-84ABK command tanks. The price was 1.58 million dollars per vehicle (3.4 million in 2020 values).

Around 150 were shipped to Kuwait before the Yugoslav Civil War and a small number after the war. It differed from the M-84A by having a desert color scheme, slightly different positioning of the smoke launchers, Racal Dana or Jaguar V radio instead of the standard RUT-1, conventional searchlight on the right turret front, lettering in Arabic, additional equipment for desert operations, and around 200 smaller changes requested by Kuwait. The Command versions had a generator for keeping the tank’s radios and electrical systems running with the engine off.

During the 1991 Gulf War, M-84s operated alongside Coalition tanks against the Iraqis, but somewhat cautiously. The M-84 could be easily mistaken for an enemy T-72 during the night or in a sandstorm and potential friendly fire was a major concern. Luckily, this did not happen. Kuwait found their M-84’s excelled in desert conditions. Sweden, Pakistan, Libya, and Egypt also showed interest in the tank. Pakistan extensively tested two examples. They completed rigorous evaluation and traveled 1,600 km without any failures or mechanic interventions. Libya ordered 200 vehicles but later withdrew the order in favor of the cheaper Soviet T-72M. Since 240 companies were contracted for making parts and components, none of the former Yugoslav republics could independently produce the tank.

M-84A4 Snajper

Even though Croatia only had a 25% share in the M-84 productions, the company that assembled the tank into a finished product was on its soil. After the breakup of Socialist Federal Republic of Yugoslavia, during a bloody civil war, the Djuro Djakovic factory still had enough parts to roll out new M-84s and pass on M-84ABs intended for export to Kuwait to the newly established Croatian Army. After the war, many M-84ABs were finally delivered to their original buyer. Some were kept in service and by 2003 modernized together with remaining M-84As. The main objective of modernization was the Fire Control System. A new FCS called Omega-84 was developed in cooperation with the Slovenian company Fotona and is claimed to be more effective than the original SUV-M84. The system had new stabilization systems for the sight and the main gun, a new meteorological sensor, a second-generation image intensifier for night operations, and a new laser rangefinder accurate up to 10 km with a probable error of +/- 7.5 m. The rest of the tank was left basically unchanged. This variant received the designation M-84A4 Snajper (Eng. Sniper). As of 2021, the Croatian Army still operates around 80 tanks of this type.

A Croatian upgrade to the M-84A4 that incorporates many modern improvements is the mid-2000’s M-84D. The tank is equipped with explosive reactive armor of Israeli origin, along with the Omega-84D FCS featuring a thermal imager, laser warning receivers, navigation and battle management systems for improved situational awareness. An air-conditioning device is installed to improve the crew’s comfort. The commander’s independent weapon station with a 50. caliber Browning M2 machine gun is also added. This rectifies the safety problem of using the old non-remotely fired heavy machine gun in a combat environment. The turret traverse system is now electric, which operates faster and more precisely than the old hydraulic system. A bustle rack that doubles as RPG slat armor protection is located on the back of the turret, as well as laser warning receivers. The engine remained the 1,000 hp V-46TK, but a new automatic transmission was installed. A more powerful engine (probably a German MTU) could be ordered. The M-84D has a modular construction that provides the potential buyer a degree of freedom in choosing the tank’s subsystems and equipment. This upgrade package was intended for Kuwait and Croatia’s Army’s, but neither of them decided to upgrade their tanks to M-84D standards yet. The tank remained at the prototype stage.

In July 2004, on the 55th anniversary of the Serbian company YugoImport SDPR, the M-84AB1 was revealed. This was a modernized M-84AB model primarily intended for export. The cost of modernization was around 1 million dollars per vehicle (1,374,000$ in 2020 values). The armor was improved by the addition of the Kontakt 5 ERA in a layout similar to the Russian T-90 MBT. Protection was further enhanced with the Shtora-1 soft-kill passive protection system. This Soviet system dating back to the early 1980s is an electro-optical jammer that uses two InfraRed (IR) dazzlers to disrupt semiautomatic command to line-of-sight (SACLOS) anti-tank guided missiles. It is also equipped with laser warning receivers that detect and inform the crew of incoming laser beams from rangefinders and target designators. This system can automatically turn the turret towards the threat and deploy an aerosol smokescreen to conceal the tank. The M-84AB1 received an electro-magnetic mine protection system, which moves the tank’s magnetic field upfront to trigger this type of mines.

The firepower was also improved. A new Fire Control System was installed, coupled with the Thales Catherine-QW gunner’s sight. This thermal imager had a target detection range of 3.5 to 8.6 km, depending on the selected level of magnification. The tank also had an optional device called TOMS that could be elevated to provide observation and measurement behind cover without exposing the tank. Improved main gun stabilizer, meteorological sensor, and crew periscopes were also installed. The newer 2A46M main gun enabled the tank to fire modern APFSDS projectiles with around 550 mm of penetration at 2.2 km, a tandem-charge HEAT projectile with around 600 mm of penetration, and a Refleks ATGM that has a range of 5 km and penetration from 700 to 900 mm. The commander could now fully take control of the main gun and remotely operate the heavy machine gun. The remote machine gun was optional and was not present on all examples. Crew comfort was improved with an air-conditioning device, and situational awareness became much better with the new navigation and battle management systems.

Two different engine options were offered with M-84AB1. The V-46TK with 1,000 hp or V-46TK1 with 1200 hp. The engines were equipped with a safety system that prevented starting with improper procedures. This system also switched the engine off if the oil pressure dropped below 2 bar. A new high-pressure fuel pump gave 16% more power with no increase in fuel consumption. The tank had a new type of tracks with extended service life from 3,000 to 8,000 km.

In 2009, the M-84AB1 was renamed M-84AS. Kuwait tested this modification but the decision to upgrade their M-84 fleet to this standard was not made. This variant can arguably be described as a commercial failure. The Serbian Army operates around 10 examples of the M-84AS.

The most recent Serbian M-84 modification is known as the M-84AS1. Not much is officially revealed about the tank, but some assumptions can be made. The tank’s base armor is probably augmented by a new domestic M19 ERA, which is claimed to be effective against tandem-charge HEAT and 3BM42 Mango APFSDS projectiles. Laser warning receivers are also present on the turret. The Explosive Reactive Armor (ERA) covers a large portion of the fighting compartment sides and slat armor protects the engine and transmission compartment from Rocket-Propelled Grenade (RPG) attacks.

The M-84AS1 received a Belorussian PKP-MRO commander’s independent thermal viewer with a detection range of 7 km and recognition range of 4 km for tank sized targets, along with a remotely operated 12.7 mm machine gun weapon station with its own fire control system and thermal imager. The commander has access to all-around low light cameras for observing the tank’s surroundings, mounted on a new type of meteorological sensor, as well as a battle management system. An improved version of the gunner’s sight called DNNS-2 TI is equipped with a thermal imager but it is not clear if this type of sight is installed on the new tank since it looks almost the same as the old DNNS-2 from the outside. The driver is equipped with a rearview camera, digitized control panel, and GPS or GLONASS navigation system. M-84AS1 is planned to have a second stage of modernization called M-84AS2. What systems will be upgraded in the second stage or how many tanks will be upgraded to the M-84AS1/AS2 standard is not revealed yet.

In the mid-1990s, the M-84AI Armored Recovery Vehicle was developed on the chassis of the M-84A with the help of Polish engineers and strongly resembles their WZT-3. It has vehicle recovery and towing equipment, along with hydraulic dozer blades for landscaping and barrier removal. A crane was mounted for lifting heavy objects or assisting in vehicle repair. For vehicle recovery, the main winch with a pulling force of 300 kN (30 tonnes) and a 200-meter cable was used. It has a mechanical drive with a two-speed transfer case. An additional smaller hydraulic winch with 20 kN of force (2 tonnes) and 400-meter cable was used for less demanding tasks. The TD-50 hydraulic telescoping crane with a capacity of 15 tonnes had a 360-degree range of motion and a maximum lifting height of 8.6 m. The vehicle was also equipped with a welding apparatus and toolsets for lighter repairs. The transport platform on the back had a 3,500 kg capacity. The vehicle was powered by the 1,000 hp V-46TK and weighed 42 tonnes. The vehicle was armed with a 12.7 mm heavy machine gun with 300 rounds mounted in front of the commander’s hatch. Only five examples were built.

Use in the Yugoslav Wars

The M-84s were operated by all sides during the chaotic and bloody Yugoslav Civil War that lasted from 1991 to 1995. This topic is very complex, and accurate information is not available for many units that used these tanks. Given the fact that T-55s and T-34s still made the majority of unit strengths, M-84s were, in comparison, less common. Right before the start of the war, Yugoslav National Army (JNA) units equipped with M-84s were:

  • 1st Armored Brigade – Vrhnika / Slovenia
  • 4th Armored Brigade – Jastrebarsko / Croatia
  • 211th Armored Brigade – Nis / Serbia
  • 252nd Armored Brigade – Kraljevo/ Serbia
  • 329th – Banja Luka – Bosnia and Herzegovina
  • 51st Motorized Brigade – Pancevo/ Serbia
  • 243rd Armored Brigade – Skopje/ Macedonia (today called North Macedonia)

Before the start of the civil war, each armored brigade was equipped with 40 tanks. The actual number once the conflict began and reinforcements were harder to come by is uncertain.

As the war progressed and former republics started to gain their independence, many of the JNA’s military vehicles were captured and used to equip newly formed units of the Slovenian Army (SV), Army of Serbian Krajina (SVK), Croatian Army (HV), Army of Bosnia and Herzegovina (ARBiH), and Army of Republika Srpska (VRS).

Early in the war, JNA’s armored units suffered heavy losses against the HV. During the battle for the city of Vukovar, the inexperienced supporting infantry often refused to advance forward without tanks leading the way. This lack of proper infantry support made the tanks easy targets for the Croatian defenders armed with handheld rocket launchers and anti-tank mines.

One example was the destruction of 9 JNA armored vehicles on the infamous Trpinjska Road (Trpinjska cesta). The Croatian National Guard (ZNG), the precursor to the Croatian Army, and members of the police, while keeping the JNA infantry at bay with mortar and sniper fire, destroyed four M-84s, one T-55, three BVP M-80 armored personnel carriers, and a TZI recovery vehicle.

Even though the terrain of that part of Croatia was ideal for the use of armored units, being open and flat, instead of exploiting weak points or quickly maneuvering to a different position on the frontline, tanks were often used as self-propelled guns or immobile hardpoints, completely ignoring the JNA’s doctrine. Tank-on-tank engagements were very rare. On one occasion, however, the HV attempted a breakthrough with several captured T-55s and probably one M-84 tank. They frontally attacked dug-in JNA M-84s and suffered losses. Three T-55s were destroyed and two were damaged.

As the M-84 had a three-man crew, the lack of a fourth crew member put an increased strain on them during maintenance due to an insufficient increase in auxiliary staff at the unit level. Enemy action was not always the cause of tank losses, as many accidents occurred due to inadequate or skipped maintenance. For example, the lack of regular cleaning of the cannon barrel could result in a deformation upon firing. The projectile would take a couple of milliseconds longer to exit and the pressure exerted for a longer duration of time deformed the barrel enough to become stuck between the cannon trunnions during the recoil cycle. In another instance, the shell exploded in the cannon breech and launched the barrel almost 30 meters in front of the tank, while the breech ended up hitting the back of the turret. Luckily, the crew survived with only minor injuries. Another flaw of the M-84 was that the commander needed to be exposed in order to operate the anti-aircraft machine gun, as it could not be fired remotely. This is the case with almost all tanks built on the T-72 platform and the machine gun was commonly left unused or removed to prevent snagging on foliage and debris. In the Bosnian hills or urban fighting, due to the low turret roof, a lack of gun elevation and depression became noticeably problematic.

The autoloading system proved reliable, but almost all hits to the lower sides of the tank ignited the ammunition storage with deadly consequences. The frontal armor of the M-84 was never penetrated during the war, but one vehicle was put out of service after it was hit with what was most likely an unexploded High-Explosive or illumination shell fired from either 122mm howitzer or 130 mm field cannon. The projectile struck the glacis plate and warped the hull longitudinally, making it structurally unsound, so it was written off. Around 40 M-84s were destroyed during the war, but some were later repaired.

The M-84s were last used against the KLA (Kosovo Liberation Army) in the Kosovo province during the 1999 NATO bombing campaign of the Federal Republic of Yugoslavia. Although the main tank used against the KLA insurgents was the T-55, the M-84s were kept in reserve for the expected land invasion. The 252nd Armored Brigade managed to keep their tanks hidden from NATO aviation and only a few tanks were lost. Many decoys were built and placed on fake fighting positions for the NATO aircraft to “destroy”.

The official NATO reports numbered 110 tanks, 200 APCs, and 545 artillery pieces destroyed. In reality, the Yugoslav Army lost nine M-84s during the 78 days of constant bombing and KLA attacks.

Since the land invasion never came and the peace treaty was signed, the Yugoslav 3rd Army, along with the 252nd Armored Brigade, nicknamed the “Invisible” Armored Brigade, withdrew from Kosovo province in front of the UN and NATO eyes almost unscathed.

While the initial M-84 version was a slightly improved T-72 licensed copy, it spurned the Yugoslav arms industry into producing a competitive Main Battle Tank that saw export success and is still in use to this day. However, due to the breakup of Yugoslavia, the production facilities were split up between the successor states, so none of them was able to keep producing the tank.
