It is also a tank destroyer armed with a M1A1C 76mm gun assembly by default, however this version is not as effective as the Sherman's, albeit it is more effective than the unupgraded gun. But unlike the M10, it has more armor, granting it longevity against anti-tank fire and giving it a more frontline role in the field. Un-upgraded, it has no defense against infantry, but it can be upgraded by having a personnel inside the turret to man the M2HB .50 caliber machine-gun. All these, makes it an effective spearhead against tanks and infantry in conjunction with the tried-and-tested M4 Sherman. Simply put, it is an upgraded tank destroyer.
