M4A3 (105mm) VVSS Sherman

The M4A3 was converted by dropping the 76mm M1 gun and replacing it with the 105mm M4 Howitzer. While the original 75mm had provided the Allies with their first gun that could effectively fire HE shells, the fitting of the 105mm provided them with a more powerful HE shell. However, their use against tanks was limited by the difficulties of hitting small targets with the howitzer and the lack of power traverse.
