The Walker Bulldog is an American light reconnaissance tank that was intended to stand up to the Soviet Cold War tanks. It entered service in 1951, successively replacing the now obsolete M24 Chaffee. It was characterized by good armor and speed. It was armed with the 76.2 mm M32 gun. Unfortunately, the engine consumed too much fuel and the tracks were extremely noisy which was undoubtedly a disadvantage of this vehicle.
A total of 5,500 tanks were produced. The first combat use was in April, 1961 during the failed Bay of Pigs Invasion of Cuba. Tanks were also found in Vietnam, where the advantage of the Soviet T-54s was felt. In 1965, the US government sold all it's tanks to South Vietnam and other interested countries.
