The M44 used the power train of the 76mm GMC M18. The engine compartment was at the front of the vehicle between the driver and bow gunner, and the commander's station was just behind the engine compartment. The driver, commander, and bow machine gunner each had their own vision cupolas, and there were pistol ports for the passengers along the hull sides and in both of the rear entry doors. The .50cal machine gun was mounted at the rear of the M44 next to a hatch in the passenger compartment roof. World War II ended before M44 could see production, however even if the vehicle had been ready for full-scale production before hostilities had ended, it was simply too big to be practical. Doctrine at that time called for a squad-sized personnel carrier, and the 24-troop capacity of M44 was just too large.
