The T2 medium tank was an American design that replaced three prototype medium tank designs started in the 1920s for conducted by the United States Army.

The first design, armed with a gun in the hull front and a smaller gun in the turret, did not progress due to lack of funding and instead the Light Tank T1E1 was used as a basis.

[1] The T2 Medium tank used the same Liberty L-12 engine found on the Mark VIII tank, resulting in a power-to-weight ratio of 24 horsepower per ton.

[2] The design of the T2 was largely inspired by the British Vickers Medium Mark II and was later developed into the M2 light tank.

The primary armament was a 47mm semi-automatic gun mounted on the turret and it initially had an additional 37mm cannon placed on the hull but that was abandoned in 1931.
