This redesigned version of the amphibian help vehicle LVT-(A) 1 was created the American Marines. In the course of numerous actions through the Pacific Campaign, the Marines became conscious of the necessity for a vehicle more heavily armed than its predecessor which had a 37 MM cannon. This improvement was essential to better counteract japan fortifications and tanks which grew in quantity whilst the War progressed. Equipped with a brand new tower housing a brief 75 MM howitzer, this vehicle ended up being popular inside battles for the conquest of Iwo Jima and Okinawa.
