T3E2 Medium Tank

In October 1932, the Munitions Board completed the specifications for the Medium Tank T3E2. The first prototype was built two years later, but after testing it was sent to be reworked. By 1936, the vehicle had undergone many improvements and was finally ready to roll out; however, by that time, its design was already obsolete and the U.S. military soon stopped using the tank. Two of its prototypes were museum exhibits for a while before they were dismantled.
