The SARC (South African Reconnaissance Car) series of armoured vehicles, known in British service as the Marmon-Herrington Armoured Car, was developed by South Africa on order from the British military in 1938. The vehicles were assembled in South African factories using components from the USA, Britain, and South Africa itself. Despite being accepted into service with the British Army, they were never actually used in combat by the British, who preferred their own domestically produced armoured cars. SARC vehicles were also in service with the armies of Cyprus, Egypt, India, Poland, and a number of other countries. They took part in the 1948 Arab-Israeli War and during the Turkish invasion of Cyprus in the summer of 1974. A total of 5,746 SARC armoured vehicles of all modifications were produced.

The most widespread modification of the SARC armoured cars was the SARC Mk IV. Over 2,000 units were produced between 1943 and 1944. The vehicle was developed specifically for British forces fighting in North Africa; however, the North African campaign ended before it could enter service. Unlike previous modifications equipped with machine gun and rifle armament, the Mk IV had a 2-pounder QF gun paired with a Browning MG mounted in its turret.

Introduced in Update "La Royale", the SARC MkIVa is one of the fastest vehicles at its rank. Apart from excellent mobility, it also boasts decent armament, with the same 2-pounder cannon that equips many early vehicles in the British tree. However, having a wheeled chassis, the SARC MkIVa is significantly less manoeuvrable than tracked armoured vehicles, especially when turning, and can struggle over rough terrain. The vehicle's armour protection is also subpar, as is its survivability in combat.
