United States M3A1 – Stuart IV – Light Tank.
The M3A1 Stuart IV was a variant of the American M3 Stuart light tank, which was widely used during World War II, particularly in the early years of the conflict. The M3A1, an improvement over the original M3, was designed to be a fast, maneuverable reconnaissance vehicle with the ability to support infantry and engage lighter armored enemy forces.
Powered by a 250-horsepower Cadillac V8 engine, the M3A1 had a top speed of approximately 56 km/h (35 mph), making it one of the fastest tanks of its time. Its operational range was around 160 km (100 miles) on roads. The tank weighed about 14 tons, which allowed for better mobility on varied terrain compared to heavier armored vehicles.
The M3A1 was armed with a 37 mm M6 gun, which was effective against early-war tanks but less capable as enemy armor evolved. It also featured 2 x .30 caliber M1919 Browning machine guns for infantry suppression and close defense. The tank’s armor ranged from 12.7 mm to 51 mm thick, offering protection against small arms fire and light artillery but leaving it vulnerable to more powerful anti-tank guns.
The M3A1 Stuart IV was widely used by the United States and its allies, including the British, where it was often called the Stuart Mk IV. It played a key role in North Africa, Europe, and the Pacific theater, though it was eventually outclassed by more heavily armored tanks like the Sherman. The M3 Stuart was in service from 1941.
