In page M4 Sherman:

"

A variant of the M4 Sherman was armed with the 105 mm M4 howitzer, which provided even more powerful high explosive armament. This variant was employed in three-vehicle "assault gun" platoons in tank battalions[5] to provide close fire support and smoke. Armored infantry battalions were also eventually issued three of these Shermans.[6] The 105 mm-armed variants were of limited use against enemy tanks due to the poor anti-armor performance of the howitzer, which was not intended to fight other tanks, though a high explosive anti-tank (HEAT) round for the 105 mm howitzer was available for self-defense.
