The M4/M4A1 81mm MMC was an M2 based motor mortar carriage equipped with the 81 mm M1 mortar. The mortar was intended to be fired dismounted from the vehicle, but could be fired in an emergency to the rear from a base inside the vehicle. The A1 modification allowed the weapon to be fixed facing forward and fired from within the vehicle.
