LVT-4 (Late Type)
The Landing Vehicle Tracked (LVT) was a class of amphibious warfare vehicle, a small amphibious landing craft, introduced by the United States Navy, Marine Corps and Army during World War II. Originally intended solely as cargo carriers for ship to shore operations, they rapidly evolved into assault troop and fire support vehicles as well. The types were all widely known as amphtrack, amtrak, amtrac etc. FMC modified an LVT-2 in August 1943 by moving the engine forward and adding a large ramp door in the rear, allowing troops to exit from the rear of the vehicle. Capacity went from 16 in the LVT-2 to 30 making earlier LVTs largely obsolete. This innovation also greatly facilitated the loading and unloading of cargo. Some vehicles received armor kits. It was by far the most numerous version of the LVT, with 8,351 units delivered.
