Comparing: M7 vs. Ram II

Development started in 1941. Initially, the vehicle was developed as a light tank; however, as the model gradually received extra armor and armaments, it was reclassified as a medium tank. Production of the M7 started by the fall of 1942. However, since the M7 was inferior to the mass-produced M4 Sherman in all parameters except speed and dimensions, the production was stopped. A total of 7 vehicles were produced.

Developed on the basis of the M3 and produced in Canada from 1942 through the summer of 1943. None of the 1,849 vehicles were ever used in action, although some were used for training purposes.
