If the LVT-1 amphibious attack tank was first used by the U.S. Marines and U.S. Army it became clear that a fire help vehicle ended up being needed seriously to protect the troops while disembarking. Hence the LVT version Alligator was made which featured protective armor and ample armament. In its turret a 37mm gun ended up being mounted. It had been also equipped with two 7.62mm device firearms.
