T20 Medium Tank
The T20 was an American medium tank that was never used or series production. It was developed, between May 1942 and February 1944.
From the tank, which was given in the course of the development of a successor to the M4 Sherman in order, three prototypes have been developed, which mainly differed in the tower and armament. A setting of T20 to active duty, however, was not planned.
