M4A3 SHERMAN 105 mm Assault Gun

The US Army used the M4A3 HVSS as assault gun in infantry units. It was equipped with a M4 105 mm L/25 howitzer on a M52-carriage in a light modified turret. The task of the Assault Gun was to give direct fire support to the infantry with high explosive - and smoke ammunition. Enemy tanks were engaged with hollow charge ammunition only in emergency situations. The 105 mm Assault Gun was equipped with a M10 ammunition trailer for spare ammunition.
