The Medium Tank M7 was originally conceived as an up-gunned replacement for the Light Tank M3/M5. The project was supposed to mount the same 75mm armament as the Sherman while retaining the light weight and maneuverability of the M3 Stuart; however, during development the weight of the prototype surpassed the US Army's standard for light tanks and crossed into the medium category[1]. The M7 had significantly less armor than the M4, boasted no greater firepower, and held only a slight advantage in top speed[2]. For these reasons, and because the M4 was already battle-tested and in full production, the M7 was put aside shortly after completing trials.
