The cupola on the right side of the gun was occupied by the tank commander and was armed with a M2HB heavy machine gun.

Empty cartridges were automatically ejected outside the vehicle through a small hatch in the rear of the turret. The T185E1 was ballistically identical to the 76 mm gun M32 of the M41 light tank but it had a quick change tube and was mounted upside down to accommodate the semi-automatic loader. The T92 had an unusual large cleft, low-profile, turret mounting a high-velocity 76 mm T185E1 rifled gun in a cradle housing between two armored cupolas. Making the T92 amphibious was deemed impractical and the light gun tank program was cancelled in June 1958. The unveiling of the Soviet PT-76 amphibious light tank pointed out that the future US light tank should be able to swim as well. It was designed as an airborne/airdropped replacement for the heavier M41 Walker Bulldog while retaining the mobility, protection level, and firepower of the latter. The T92 Light Tank, or 76-mm Gun Tank, T92, was an American light tank developed in the 1950s by Aircraft Armaments.
