M4A3E8 SHERMAN 105 mm Assault Gun

The US Army used the M4A3E8 (HVSS) as an Assault Gun in Armored Infantry Battalions. It was equipped with a M4 105 mm L/25 howitzer on a M52-carriage in a light modified turret. The purpose of an Assault Gun was to give direct fire support to the infantry with high explosive - and smoke ammunition. Enemy tanks could be encountered with hollow charge ammunition only in emergency situations. The 105 mm Assault Gun was equipped with a M10 ammunition trailer for the spare ammunition.
