LVT (A)(1) |
Had a M3 light tank turret mounted.1 Gun used a gyrostabilizer.1 Also had "manholes" at rear with .30 cal MGs installed.5 These were quite dangerous and were later removed.5 There were periscopes for the crew to see out.1 The engine was installed between the crew and the cargo compartment in the rear.1
When exiting the vehicle the passengers would have to go over the side as there were no doors in the back.1
The 37 mm gun fired a 1.9 lb shell at a muzzle velocity of 2,900'/sec.5
The Marines would replaced the 37 mm gun with the E7 flamethrower.
Usage

Many of these were used at Bougainville and New Georgia.
