This redesigned version of the amphibian support vehicle LVT-(A) 1 was developed
for the American Marines. In the course of numerous actions during the Pacific
Campaign, the Marines became aware of the need for a vehicle more heavily armed
than its predecessor which had a 37mm cannon. This improvement was necessary
to better counteract the Japanese fortifications and tanks which grew in number as
the War progressed/ Equipped with a new tower housing a short 75mm howitzer,
this vehicle was widely used in the battes for the conquest of Iwo Jima and Okinawa.
