Izhorsk Improvised Armored Vehicles

Soviet Union (1941)
Improvised Armored Vehicles – Estimated 100 Built

It is hard to stress how dire the situation was for the Red Army  in the summer of 1941. In as little as two months, 10,000 tanks had been lost to the German Army and her allies. Therefore, factories across the Soviet Union began to produce a myriad of improvised tanks and armored cars. The Izhorsky plant in Leningrad was one such producer, however, rather than up-armoring tanks like most other factories, Izhorsky up-armored and militarized trucks for combat, equipping some machines with a 45mm gun, and even going as far as creating a crude turreted armored car.

Izhorskiye pre-war

The Izhorskiye Zavod (Izhora Plant) was established in 1722 in Saint Petersburg under the orders of Tsar Peter I, to manufacture items for the Russian Navy. The plant had a long career manufacturing naval goods including armor plates for their ironclad and pre-dreadnought ships. In 1906, the plant was awarded its own flag. Some time in the early 1900s, the plant moved onto vehicle manufacture.
Before the war, the Izhorskiye (Iszhorky) plant was one of Leningrad’s largest producers of vehicles. Izhorsky manufactured such iconic vehicles as the FAI, BA-I, BA-3 and BA-6. Izhorsky also manufactured armor plates for tank production, these plates were mostly used in the T-37A, T-38 and T-40 tanks. Izhorsky had a long and proud history of manufacturing armored vehicles, and on the eve of WWII, the plant was producing armor plates for the T-40 amphibious tank, as well as military and commercial trucks.

Desperate measures

After Germany invaded the Soviet Union on the 22nd of June 1941, scores of Soviet tanks were lost. The Soviet Union was in desperate need for any armored vehicles that could stem the tide of the German invasion. On the 20th of July 1941, resolution 219ss was passed. This was a resolution for factories across the Soviet Union to begin manufacture of ‘bronetraktors’ (i.e. improvised tanks), and to up-armor tanks such as the T-26. This resolution did not specify that trucks should also be up-armored, however, Izhorsky proceeded with the implementation of armor on trucks.

A GAZ AA Truck. The key way to identify this truck over the ZIS-5, is the rear suspension. Notice the leaf suspension that looks as though it should have a second road wheel.
Other plants went down different routes, with the HTZ plant in Kharkov manufacturing HTZ-16 tanks on modified SkHTZ-NATI chassis (the civilian version of the STZ-3). The Odessa Ship works manufactured the ‘NI’ Odessa Tank on the STZ-5 chassis too. Other experiments were conducted in Stalingrad on another tractor tank based on the STZ-3, however these were never fully completed.

IZ trucks

On July 8th 1941, Decree of the Military Council of the Northern Front 53ss was passed. This decree was for the Izshorsky plant to manufacture 20 ZIS-5 trucks with a 45mm field gun placed on the rear of the truck with a partially armoured cab and engine compartment.
As it was, three different chassis were available for these improvised armored trucks, the GAZ-AA, the ZIS-5 and the ZIS-6. The GAZ-AA and ZIS-5 trucks were equipped with plates that are reported to have been between 3-10 mm thick, that covered the engine and crew compartments. The driver of the truck was situated on the left hand side, with a vision slit cut into the armor. To the right of the driver was a machine gun, which was most likely a DP-28 or DT-29.
The engine compartment was completely sealed in, with two small access hatches either side of the engine, along with two armored air intakes over the front grille of the truck. The suspension was unchanged despite the weight increase.

The most common variant of the IZ armored truck, with a 45mm gun placed on the stowage compartment of the truck.
The rear of the truck was built up with armored sides, however, still had an open rear and roof. The cargo portion of the truck was left unarmored, with this new armored structure placed on top of the folding wooden sides. According to the surviving records and photographs, these trucks were armed with either a 45mm gun, a quad maxim gun mount, or nothing at all, functioning more as an armored personnel carrier. The 45mm gun, when placed onto the truck, used the gun shield as part of the armor at the front of the new fighting compartment, with the gun facing forward, and the barrel extending over the engine deck. Wheels were retained on the gun.

An IZ captured by Finnish forces. This truck has had the 45mm gun removed.
These vehicles were called  “IZ”, as the factory that produced them was the Izhorsky factory. It is agreed that, after the initial 20 vehicles with 45mm guns were produced, the plant continued to manufacture armoured trucks in the layouts already described. Roughly 100 of these vehicles were produced from August until December 1941. There was little variation from vehicle to vehicle other than armament. Due to the thin armor of the IZ trucks, performance was not hindered greatly, however the weight of the truck was increased.

ZIS-6 armoured car and other conversions

Izhorsky also briefly experimented with the manufacture of an improvised armored car based on the ZIS-6 chassis. The rear of the truck was converted into a fully fledged armored car. This had a box created on the rear of the truck, that on the top had a BA-6 turret. The engine deck was covered in the same pattern armor that the IZ trucks were plated with. It is thought to be a BA-6 turret rather than a T-26 turret due to the weight differences between the BA turrets and the T-26 turret. The thickness of the armor on a BA turret was 9mm thick, whereas a T-26 turret was 13mm thick. Only one ZIS-6 armored car seems to have been manufactured, and appears in one photograph.

In addition to the creation of a new armored car, Izhorsky also took back armored cars for repair. Some of these vehicles were themselves modified. One such conversion was done to a BA-10. After being returned to the Izhorsky plant, the car was cut down in size. The rear portion of the car, including the rear most drive wheel, was removed. In its place a simple armored cab was placed with a command cupola from what appears to be a BA-27. This vehicle was now an ambulance. It was captured intact, and actually pressed into German service as an ambulance.

Combat deployment

The first of these “IZ” were delivered to the defenders of Leningrad on the 15th of July 1941. It is unknown when the last example was manufactured. Estimates range from as low as 25 produced to upward of 100. These trucks were reported to have been used on the western front until early 1943. They were only issued to the Leningrad People’s Militia. Several of these vehicles fell into German hands. However, only one is known to have served in the Wehrmacht.
A still greater operator of these trucks was Finland. As these vehicles were manufactured in Leningrad, they were only available here during the siege. Large attempts were made by the Red Army to push back the Finnish forces to the north, to allow for some much needed breathing space around Leningrad. Early actions from September to November allowed a small number of IZ’s to fall into Finnish hands, who pressed them into service.
It is undeniable that these vehicles were a product of desperation. These vehicles likely performed poorly, as expectantly the trucks with 45mm guns would have been very top heavy. It is far to say that the APC version of these trucks would have been moderately more successful, however their true combat effectiveness is a mystery.

An IZ that has been abandoned. This vehicle is likely based off the ZIS-5 chassis, as the armored cab is different to that of other IZ’s.

IZ also experimented with a BA-10 that was cut down and converted into an ambulance. as this picture illustrates, the car was captured by the Germans and pressed into service.

Soviet Navy Armored ADG Lorry

Soviet Union (1941)
Improvised Armored Lorry – Estimated 3 Built

Desperate Times

After the annexation of Estonia, the Red Army occupied the country and absorbed military equipment into the Red Army. After the bloody nose that the USSR was dealt by the Wehrmacht, the Army and Navy were desperate for armor. The Navy’s solution was to create an improvised armored lorry based on an Austrian ADG truck. It featured a large, armored crew compartment, and a small turret armed with a machine gun. Unfortunately, due to the nature of this conversion, there is very little documented evidence of its history. The vehicle doesn’t even have an official name. Some suggested are: “Soviet Naval ADG”, “ADG-R” (ADG-Russian), or perhaps simply Improvised ADG, however this article will refer it to as the “Armored ADG” for simplicity.

History of the ADG lorry

What is known about this truck however, is that it is of Austrian heritage. In 1911, the Daimler Motoren Gesellschaft absorbed the Austrian Motor company Osterreichishe Automobil Gesellschaft. Under this partnership, the company began to produce trucks for civilian use and Imperial Army use. In 1932, Austro-Daimler (AD) began work on a new 4×6 three axle design truck. This truck had many modern features including a longitudinal sprung rear suspension with two wishbones. this meant that the truck was very maneuverable over rough terrain. This new truck was powered by a 6-cylinder petrol engine that produced 65 hp, and boasted seven forward and three reverse gears.

It was called the ADG, however after 1936, the design was reworked slightly to become the ADGR. The ADGR is discernible by the twin sets of rear wheels, rather than one. Other variants include the ADGK and the ADGT, the latter being a fuel truck. In all, 185 ADGs and 361 ADGRs were built between 1932 and 1940. After the German occupation of Austria, the AD company was merged with Steyr. The Steyr variant of the ADG was called the Steyr-640. Photographs of this truck exist in operation with Wehrmacht units, mainly on the Russian front, and one survives today in the Austrian Military Museum.

Unfortunately this is where the the story becomes hard to trace. The only available records seem to show that the only foreign nation to purchase ADGs was Romania.

Context: Estonian SSR

After the Molotov-Ribbentrop Pact of 1939, the USSR was given free reign to administer authority over Estonia, so the Soviets invaded on 16th June, 1940. Much of the Estonian military surrendered immediately and much of the Estonian military hardware was put into storage. Only the Estonian Independent Signal Battalion stationed in Tallinn at Raua Street were resistant.
The German invasion of the USSR a year later, on June 22nd 1941, was a massive surprise to the Red Army. Scores of vehicles were lost, all of which were needed desperately for defense. It was at this time that the Estonian people rose up against the NKVD, in an Estonian nationalist group known as “The Forest Brothers”.

Theory – Soviet Vehicle

One source claims that the “Zagradotryad” Shipyard in Tallinn created at least two “police” vehicles to suppress the uprising. It is likely that this vehicle is that police vehicle, seeing as though Russian letters can be seen on the side of the lorry. From the relevant photographs of this “Armored ADG” it can be seen that it was probably operated by Soviet Naval personnel – one photograph in particular appears to have dead naval troops hanging from the entry hatch of the vehicle, their black uniforms and helmets fairly clear. The vehicle is believed to have been operated in June, 1941.

Other Theories

In the writing of the article, two other theories have surfaced as to the vehicle’s origin. Originally, it was thought that this vehicle might belong to the Forest Brothers – partisans operating in Latvia and Estonia. The suggestion was that the German 18th Army, which fought alongside these partisans, might have donated the ADG truck to the partisans, who then armored it up.
Similarly, it was also thought that there is a possibility of the armored lorry belonging to the Estonian Independent Signal Battalion stationed in Tallinn at Raua Street. However, this particular theory was speculative at best.

Design of the improvised lorry

It is evident from the photos that the rear section of the truck was built up into an armored superstructure, probably about 7 mm (0.28 in) thick. The new superstructure also featured a four-six sided turret with a Maxim machine gun, of which there were two different shapes, tall and thin, or short and wide. It is unclear how many were produced, but according to photos, possibly two (or three). The suspension appears slightly stressed due to the new superstructure, but it may be the case that the superstructure was just poorly fitted to the chassis, thus giving the illusion of the broken suspension.

Possible Combat Performance

The “Armored ADG” seems to have been armed with a Maxim gun, with armor that was between 7-10 mm (0.28-0.4 in). If it was fighting against infantry, it is safe to assume that it would have performed relatively well, with “bullet proof” armor. It was armed with a machine gun, meaning this truck could have been an able opponent. However, against any form of tank or well-armed tankette, this machine would have been an abject failure because the armor would be insufficient against weapons of a caliber of 12.7 mm (0.5 in) or more. Indeed, one photograph of the “Armored ADG” appears to shows a penetration in the turret. The biggest drawback of this vehicle were its high silhouette, thin armor, and apparently crude construction. That being the case, it is safe to assume that this lorry was a true product of desperate times.
It has been suggested that at least one of the vehicles was destroyed on the Peterhof Highway. It is fair to surmise that perhaps one was able to retreat with other Red Army units before the encirclement of Tallinn.
It is reasonable to estimate that the truck would have been close to its load bearing capability with the additional armor and the improvised turret. Therefore, the “Armored ADG” would have been a very clumsy truck. While we have no definitive information on this improvisation, however the regular ADG’s were in themselves very good vehicles. With their double wishbone suspension, the rear drive wheels could move interdependently of each other, making terrain traversal very easy. It is unknown whether the extra armor on the side impeded the swing of each wheel arm, although it does look as though it was the case.

Showing its improvisation, this “Armored ADG” differs from the other two photographed by having a far more squat turret with 5 sides. This photo also clearly demonstrates the type of access that the truck had. There is a door on the right side of the truck and one at the rear. It looks as though it was hit with at least three 37mm shells in the upper hull, and once or twice in the turret. It is likely that the lorry was set on fire, as the tires appear to have been burnt out, and the hull appears charred. In this photograph we can clearly see the Soviet Naval troops who have been killed. Source: Francis Pulham Collection

Sidenote: Other Conversions in Estonia

In addition, there is some evidence to suggest that Red Army forces also improvised other vehicles in Tallinn, such as a tractor tank based on the STZ-5. However, its history remains as unclear as this armored lorry, as there are only two known photos.
A rear view of what appears to be a tractor tank based on an STZ-5 next to an Estonian Arsenal Crossley armored car. The Arsenal Crossely armored car was considered obsolete, but was possibly taken out of storage to fight in the war and was given to the Estonian 22nd Territorial Rifle Corps, and one was sent to storage in Dvinsk.

There are rumors of one serving at Leningrad. Seeing as though information is scarce, this leads only to speculation. It is rumored that this is a photo taken on Saaremaa Island, Estonian SSR, and a handful of improvised tanks based on the STZ-5 were built. It is also rumored that this photograph was taken at Leningrad. It is, however, much more likely that this was another policing vehicle made by the Soviet Navy at Tallinn and was deployed in the same manner to the Armored ADG. However, due to the lack of clear sources, none of the three claims mentioned can be totally substantiated.

Seemingly another Izhora Bronetraktor in the above photograph. It appears to have toppled over into a ditch and is being inspected by Germans and locals. The turret is facing the rear, and it is possible that it was trying to flee before it fell over.

Red Army Auxiliary Armoured Vehicles, 1930–1945 (Images of War)

Red Army Auxiliary Armoured Vehicles, 1930–1945 (Images of War), by Alex Tarasov

If you ever wanted to learn about probably the most obscure parts of the Soviet tank forces during the Interwar and WW2 – this book is for you.

The book tells the story of the Soviet auxiliary armor, from the conceptual and doctrinal developments of the 1930s to the fierce battles of the Great Patriotic War.

The author not only pays attention to the technical side, but also examines organizational and doctrinal questions, as well as the role and place of the auxiliary armor, as it was seen by the Soviet pioneers of armored warfare Mikhail Tukhachevsky, Vladimir Triandafillov and Konstantin Kalinovsky.

A significant part of the book is dedicated to real battlefield experiences taken from Soviet combat reports. The author analyses the question of how the lack of auxiliary armor affected the combat efficacy of the Soviet tank troops during the most significant operations of the Great Patriotic War, including:

– the South-Western Front, January 1942
– the 3rd Guards Tank Army in the battles for Kharkov in December 1942–March 1943
– the 2nd Tank Army in January–February 1944, during the battles of the Zhitomir–Berdichev offensive
– the 6th Guards Tank Army in the Manchurian operation in August–September 1945

The book also explores the question of engineering support from 1930 to the Battle of Berlin. The research is based mainly on archival documents never published before and it will be very useful for scholars and researchers.
