Comparing: M7 vs. M4A2E4 Sherman

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.

Work on this experimental vehicle started in March 1943. Two prototypes were built by July. The vehicle passed trials, but was never mass-produced or used in action.
