The LVT, or Light Vehicle Transport, was designed to haul vehicles and equipment up to 4,500 pounds during warfare; the idea was to haul equipment from ships to shore quickly, but it soon became apparent that they lacked proper armor protection and their suspension was unreliable on rocky terrain.
Consequently they were then used as assault vehicles; retrofitted with better armor, they could carry 18 fully equipped men quickly into battle. By war’s end there were 18,621 LVTs delivered to the war unit.
