Republic of South Africa (1975)
Infantry Combat Vehicle – 1,400+ Built
“Ratel”, the African Bush Fighter
The Ratel Infantry Combat Vehicle (ICV) takes its Afrikaans name from the South African honey badger. This animal, despite its small size, is a fierce creature which is able to absorb a large amount of physical damage as well as dish it out with its long claws. The Ratel vehicle is therefore well named as it armament and mobility make it a formidable opponent. It was designed and produced at a time when South Africa was subject to ever more strict international embargoes because of its segregation policies (Apartheid). The historical background is also set in the backdrop of the Cold War in Southern Africa which saw a steep rise in liberation movements backed by Eastern Bloc communist countries such as the Soviet Union.

During the mid-1960`s there was a growing realization in the South African Defence Force (SADF) that foreign imported armoured troop vehicles, such as the Saracen, were not up to the task against modern threats and the requirements based on the challenges found in the Southern African environment. What was needed was a highly manoeuvrable, ultra-reliable and easy to maintain ICV armed to the teeth, which could fulfil the doctrine requirements being developed by the SADF for mobile warfare based on an indirect approach and low force density. The “indirect approach” is based on surprise and flanking attacks and avoids frontal attacks on well-prepared defended positions. “Low force density” describes the ratio between the number of troops and the ground they need to hold. In the SADF’s case, few troops over a large area necessitated quick movement, something the Ratel ICV was built for.
Design work on the 6×6 wheeled Ratel began in 1968. It was intended to carry troops rapidly into and out of battle, making mobility the primary characteristic, followed by firepower and armor. The first prototype Ratel was made of soft steel which allowed quicker modification work. The first four production Ratels were put through their paces at the Elandsfontein vehicle testing grounds near Pretoria in 1975. The first batch of 13 Ratels (Mk1) was delivered from the production line at Sandrock-Austral in Boksburg from 1975 onwards.
After operational field trial tests, improvements were implemented which focused on enhancing the Ratel`s “bush breaking capability” such as large covers to protect external headlights (which were covered by mesh wire at first) and a screen cover to keep leaves from being sucked into the engine. These modifications were only later designated as the Mk2 standard. The Ratel 20 was put into production and operationally deployed in 1976. The final upgrade of the Ratel to the Mk3 standard was implemented in 1985 and included more than 135 modifications such as an improved cooling system, additional fuel filters, digital acceleration meter and more robust bush protection (moving the front exterior lights lower and the steps to enter and exit the Ratel were strengthened).

The Ratel allowed the SADF to wage conventional warfare from 1976 onwards as the South African Border War escalated and cross-border operations became more frequent and more complex. The primary liberation movement for South West Africa (Namibia), the “South West Africa People’s Organization” (SWAPO) conducted increasing daring cross-border sabotage, intimidation and assassination raids from their bases in Angola into South West Africa. Ratels, with their high speed and endurance, were employed to intercept SWAPO raiders when they crossed the border. High-mobility operations saw Ratel formations often consisting of battalion-sized columns with mixtures of other South African produced military vehicles (Buffel, Eland, Samil etc.) leaving their bases located near the northern border of South West Africa to conduct deep incursions into Angola against SWAPO training and logistic camps.
These cross-border incursions by South Africa saw an alliance between itself and the National Union for the Total Independence of Angola (UNITA) which were engaged in a more conventional war against the Cuban and Soviet-backed Popular Movement for the Liberation of Angola (MPLA) and the Angolan conventional army, the People’s Armed Forces of Liberation of Angola (FAPLA), for control of Angola. The war escalated as Cuba, backed by Soviet advisors, sent troops and equipment into the fray. The SADF doctrine of mobile warfare made maximum use of the Ratel`s characteristics and allowed them to influence the flow of the war and hold the line against numerically superior adversaries until peace was declared in 1988.
Approximately 1400 Ratels were built. They were fielded with SADF units such as the 61 Mechanised Battalion Group, 32 Battalion and 4 South African Infantry Battalion. Other units that made use of the Ratel were Citizen Force Mechanised Infantry units as well as other branches of the then SADF such as artillery, engineers and signals. Ratels have also been exported to Cameroon, Djibouti, Ghana, Jordan, Libya, Morocco, Rwanda, Sahrawi Arab Democratic Republic, Senegal, Yemen and Zambia.
According to Major General Roland de Vries (retd.), who was closely involved with the Ratel design and doctrine development, the Ratel was the best vehicle ever made for the ultra-mobile African bush warfare. The terrain it operates in is some of the most hostile in the world, which alone inflicts harsh punishment. Characterized by its large wheels, swiftness, bush breaking ability, and versatility as a weapons platform, it was a fearsome adversary in skilled hands during the South African Border War.

The Ratel`s 6×6 wheeled configuration was designed for the African battle space and characterized by its versatility and cross-country capability. A six-wheel 14:00 x 20, run flat (designed to resist the effects of deflation when punctured) configuration offered more reliability and required less maintenance than tracked vehicle such as the American Bradley and Warsaw Pact BMP. The Ratel has 350 mm of ground clearance and can ford 1.2 m of water. Unintentional tests have proven that the Ratel is as amphibious as a brick. The Ratel makes use of the Büssing D 3256 BTXF six-cylinder direct injection turbocharged diesel engine which produces 282 hp (14.8 hp/t). The engine is located at the rear left of the vehicle and proved more than sufficient to navigate rough terrain and to push through dense bush and small trees.
The power pack can be field stripped and replaced in roughly 30 minutes by two men using a crane. The engine is coupled to an automatic powershift gearbox containing a hydrodynamic torque converter which eases driving. The gearbox can also be operated manually and had a mechanical emergency gearshift. The power is transmitted to the three axles in two stages with a final decrease using a planetary gearing which is located in the wheel hubs. Each of the three axles has their own lockable differential and longitudinal differential locks. The suspension utilized progressive acting coil springs as well as large hydraulic shock absorbers.
Endurance & Logistics
Remarkably, the Ratel`s operational range was a 1000 km via road and 600 km cross country, which enables flexible force movement in order to achieve surprise. This implies long missions over rugged and variable terrain with little logistical support. It needs to be well armed and self-sustaining, carrying its own supplies, spare parts and a section of infantry. All Ratels can operate over long distances and are loaded with all sorts of equipment and supplies. Spare wheels are lashed to the roof of the hull, while food is stored in every available space (as well as a few cases of beer). The average number of 7.62 mm machinegun rounds carried is at least 6000. All Ratels feature tactical radio communication which enables reliable command and control which further enhances the vehicle’s force multiplier effect. Spare whip aerials for the radio are always carried somewhere on the hull as they have a tendency to break when driving through the brush. The Ratel is equipped with two drinking water tanks as standard and each vehicle carries a cooking stove, tool kit, tow bar, cable and spare parts. One in every four Ratel’s carries a field shower kit. The overall emphasis is on self-sufficiency, from fire support to first aid.
The Ratel was the first wheeled ICV to ever enter service. It featured a proper commander’s cupola which offered a 360-degree field of vision. The commander was located on the left side of the turret while the gunner sat on the right. The driver’s compartment is located at the front and center of the vehicle, from where he has an excellent 270-degree visibility through three large bullet-resistant windows. During the battle, the driver can activate three armored shields which pop up and to cover the windows for extra protection. When the armored shields are activated the driver uses three day-periscopes with a view of the front, left and right to drive. The driver can enter and exit the vehicle from either a roof hatch located above his seat or through the interior of the vehicle. All Ratels can be fitted with a small crane jib or tow bar at the rear which is used to tow a damaged vehicle out of action.

The hull has entry doors on the left and right which are operated with a hydraulic system to ensure the doors close at any angle while the door at the rear of the hull is manu-matic. The Ratel has several roof hatches which can be used for loading and emergency exiting should the need require.
A Ratel 20 carries a standard complement of three crew and up to eight fully armed and equipped troops. The Ratel`s interior can be considered crowded and although not standard procedure, space can be found for an additional three passengers when required. The mounted troops sat back to back allowing them to shoot out of the four firing ports located on either side of the vehicle. The section leader was also the vehicle commander and sat on the left side of the turret from where he could see through the driver’s window. Located at the rear of the vehicle, another hatch could be equipped with a 7.62 mm Browning on a mount which was primarily used for local and air defense. The success of this air defense arrangement was useless but was sometimes used to great effect in the ground role. The Ratel carries four 81 mm smoke grenade launchers, two on either side of the turret.
Ratels could either fight through an objective by firing its main weapon while the infantry fired out of the firing ports or alternatively, the Ratel would fire its main armament while the infantry dismounted from the entry doors on either side of the hull. While on operations, the roof hatches were often kept open due to the heat. The infantry often sat on top of the hull whenever safe to do so.
The Ratel was designed for speed and mobility at the cost of armor. The Ratel has effective thickness of 20 mm (at 60 degrees) over the frontal arc. The upper hull sides are 8 mm (at 65 degrees), lower hull 10 mm (at 90 degrees), rear hull 10 mm (at 90 degrees), top hull 6 mm and floor hull 8 mm. The frontal arc offers protection against 12.7 mm armor piercing (AP) rounds while the rest of the hull is sufficiently protected against shrapnel and 7.62 mm AP rounds. Ratels are extremely susceptible to fire from Russian-supplied 20 mm and 23 mm anti-aircraft weapons (often employed in a ground defense role by the MPLA and Cuban forces). Contrary to popular belief, the Ratel, although designed with the threat of mines in mind, does not feature a V-shaped underbelly. It’s mine resistance is derived from the hull`s height above the ground, which is due to its large oversized wheels. The wheels are also designed to blow off and thereby disperse some of the explosive energy. Additionally, the wheel arches form a V-shape which helps deflect mine blasts. During the South African Border War, only one Ratel mine fatality was recorded when a Ratel drove over a double anti-tank mine which detonated under the belly of the vehicle during Operation Meebos in 1982.
The Ratel Family
The Ratel platform served as the basis for an entire family of fighting vehicles which forms the backbone of the South African Mechanised armed forces and includes the basic Ratel 20, Ratel Command, Ratel 60, Ratel 90, Ratel 81, Ratel ZT-3, Ratel Ambulance, Ratel Logistic, Ratel EAOS and the Ratel Recovery.
Ratel 20 – 1975
The Ratel 20 carries three crew members and can accommodate anywhere from eight to eleven mounted infantry (mission dependent). In line with the doctrine of offensive operations, which requires rapid closing with and destruction of the enemy, the main variant of the Ratel features a two-man turret with the first ever dual fed F2 20 mm quick firing cannon. This is a licensed copy of the French GIAT gun and produced in South Africa by LIW, which later became Denel Land Systems. The cannon’s primary purposes are to lay down sustained suppressive fire, engage enemy troops and to destroy soft skinned and lightly armored enemy vehicles. The canon can elevate +38 degrees and -8 degrees. The 20 mm cannon produces a high rate of fire to support dismounting infantry with high explosive (HE) rounds effectively up to 2000 m and armor piercing (AP) rounds up to 1000 m. The Ratel 20 also carries three 7.62mm Browning machine guns, one coaxial, one on the turret and one at the rear of the vehicle, which was primarily used for local and air defense.

Was trained technicaly on the ratel at that stage one of the best .This was in 1976 june .Eccelent arictcle !!
Well done. Was a foot soldier. Never had the privilege to work with these machines
Did training at MLV Bloemfontein in 87 on Ratel 20. Did ops Hooper with these machines 87-88.
OPS Packer 1988. Ratel 81 platoon. Unforgetable experience. One of the best fighting machines in the world
Great article back to the basics of military armour. A visual trace back into the past. Thanks for the great insight.
Very good article thank you.
What is the difference between Ratel and the Belgian Sibmas?
And as a side note, The Malaysian also the ONLY user of Sibmas (Sibmas with 20mm turret, 90 cockerill turret, command and ARV variant) and still used them efficiently and bringing to full circle, they obtained the Ingwe missile to be equipped on Deftech AV8.
Greetings Alex. The Sibmas was based on the original Ratel prototype with the aim to export which wasn’t very successful. As you noted only Malaysia bought it. The Sibmas has a more powerful engine and is somewhat lighter giving it more hpt. The Sibmas is amphibious making it ideal for the wet environment of South East Asia whereas the Ratel floats like a brick.
Will we be seeing a separate article on the Sibmas?
Not from my side. I specialise in SADF\SANDF only.
The Ratel ZT-3 only carries 12 missiles at a time, three of which will be loaded into the launcher and not 15 missiles as this article implies. Also it is not used in the reconnaissance role. That role is carried out by other systems such as the other Ratel variants, Rooikat and Rooivalk.
I have forwarded your comment to the author of this article and he will look into it.
Thanks for the input!
My father Len Bramwell worked for Kentron in 1980’s.
He is 89 years old now. He now lives in England. i am visiting his home at the moment. He has
Just dug out his first drawings of the Ratel which he did at his home in Kempton Park. He designed the initial concept of the rocket system on the turret mounted on the Ratel. Early copies of his work are returning with me to South Africa to be displayed at the Mechanized military museum in Bloemfontein.
Very glad to hear they will find a place in the museum. If you have copies, please forward them to me so I can add them to the article.
Hi dewald. I can take photos on my dad’s tablet of all his illustrations. Where shall we send them to. He’s very proud of them. ☺️
Or as a message on our Facebook page!
Photos of Len Bramwell’s early Ratel illustrations have been
e mailed through. We really look forward to having them appear on this excellent website.
Thanks for the excellent guide
I have a picture of the Ratel 60, with mortar fitted, if you would like to use it. As well as the Ratel 81.
Thank you Gordon. You can pm them to me on Facebook if possible.
I will do so this weekend.
I forgot to ask, should I send the photos to your personal Facebook page or the Tank Encyclopedia’s page?
Okay, why not?
So how much longer are the Ratels going to be in service until the Badgers replace them?
For the foreseeable future as only 238 Badgers are being built compared to the 534 Ratels (numbers from Wikipedia). I believe the plan for now is to only replace the Ratels of 1SAI and 8 SAI, all other units using Ratels will continue to use them.
Excellent article !!
61 Mech, 1987, Operation Modular, Crew commander 32B.
Ops Packer 1988. Ratel 81 mortar Platoon. Unforgetable experience. What an honor to serve in the SADF with the best fighting machines in the world. Ratels I salute you!
In my much earlier years when I was on the reasonably high branch of a corporate tree I was invited to visit a commercial vehicle assembly plant and I think it was in Pretoria (Rosslyn?) A special treat was to be taken through a subway which went under the road and emerged in another plant on the other side of the road where SADF vehicles were being assembled. Sadly age (76) and Alzheimers are taking their toll and I cannot remember the conventional or the military tradenames. If this is not still confidential are you able to help me relive that interesting day?
I was in 1SSB 1985/6, trained on Noddy’s but deployed to Angola as crew commander on Ratel 90 from Dec 85-86. Additionally, deployed for Ops Excite in 88, again in Ratel 90. So I am pretty familiar with the Ratel, mostly in it’s 90 and 60 forms.
My question .. in the movie The Hurt Locker, I swear I see US forces using Ratel’s in many scenes? Did SA ever sell the Ratel for use by US forces? Or, given the movie was filmed in Amman, is the appearance of Ratels merely as a result of being filmed in Jordan, who I believe did acquire Ratels from SA?
US never used Ratels to our knowledge.
In the article it says that the 90 mm HEATFS needed multiple hits to immobilize enemy yanks such as the T55 and T62s
However to my knowledge the 90 mm HEATFS has 320 mm of penetration against RHA and neither tank has that much armor so did the rounds penetrate and the T-55s / T62s survived or was it something else?
