NotesThe first Combat Cars were the Cavalry’s way of getting round the restrictions which stated that Tanks were for Infantry use only, hence the name Combat Car. These were based on the earlier light tank T5 design and had changes made to the position of both the engine and turret. This the first model had a D-Shaped turret with no Cupola and was armed with two machine guns. In 1940 the M1 combat car became the M1A1 light tank.
