The LVT or landing vehicle tracked was used extensively by the U.S marines in world war 2 as it had the ability to drive off of a ship, drive up to the beach, go up and over the defences and all the while give much needed fire support to the troops who would disembark from the rear. In conventional craft such as those used in the normandy landings, there is little close fire support and the ramp drops forwards, allowing the troops to be mown down by fixed machinegun positions. The LVT was used in all major Pacific landings after Guadacanal, including Tarawa and Iwo Jima
About this creation
Fire support is provided by browning .30cal and browning.50cal machineguns. Some were modified to carry no troops but instead packed armor and either an M3 37mm turret or a 75mm howitzer turret from an M8 motor carriges.
