LVT2's cab was placed a small distance from the bow, and the cab had two bottom-hinged outward-openeing escape windows for the crew. LVT2, known as Water Buffalo, had a cargo capacity of 5940lbs (2690kg), and incorporated torsilastic suspension, which involved springing the road wheels on rubber springs. The track of LVT2 was made up of two chains, each with a pitch of 4" (10cm), which were attached to each other by steel crossbars and the large propellor-like grousers. The new W-shaped grousers provided almost twice the pull in water compared to the curved grouser on the LVT1. LVT2 also used the engine and transmission of the gasoline-powered light tank M3. Though not officially differentiated, there were two different LVT2 models with the only change being a slight difference in the length of the gun rails.

Initially created for the Army, the LVT(A)2 was an LVT2 with the 10- and 14-gauge steel on the cab front and rear, hull front, and pontoon sides replaced with armor plate. The armored cab was fitted with a roof with two hatches equipped with periscopes, and there was a single observation panel in the left front side of the cab that the driver could open for direct vision. The additional weight brought on by the armor reduced the LVT(A)2's cargo capacity to 4950lbs (2250kg).
