90mm Gun Motor Carriage M36 at the US Army Heritage and Education Center at Carlisle Barracks.

The large 90mm gun on this vehicle is imposing and indicates the power of these tank destroyers. As no coaxial machine gun was mounted and the gunner was stationed to the gun's right side, the left side of the gun shield was bereft of apertures. Track grousers and spare track shoes are stowed on the hull sides, and bosses for auxiliary armor can be seen on on the hull front and sides. (Photo by Richard S. Eshleman.)

This vehicle was also based on a late-production hull, since the auxiliary armor bosses have been omitted from the rear sides. The drivers' periscopes in their open hatch doors can be seen. The vehicle's siren is placed just outboard of the left-hand headlight group.

The semi-circular gun shield helps differentiate this vehicle from the M10, as the M10's gun shield was more pyramidal.

The large turret bustle helped to counterbalance the heavy 90mm gun as well as provide an ammunition stowage space. Placement of the .50cal machine gun mount can also be seen.

The wide air intake grilles were a hallmark of the GAA engine. The filler cap in the foreground was for the left rear fuel tank, and the one between the turret and the air intake grilles was for the cooling system.

The interior of the turret is shown here. A folding frame for a canvas foul weather cover is stowed above the gun shield, and a fire extinguisher is mounted on the turret front wall. The loader sat to the left of the gun, while the other two turret crew were positioned to its right. (Picture from TM 9-374 90-mm Gun M3 Mounted in Combat Vehicles.)

The hull of this vehicle is that of the late-production M4A3 with stowage rearranged to accommodate 90mm ammunition. Note the retention of the bow machine gun and the absence of a muzzle brake. (Picture from TM 9-748 90-mm Gun Motor Carriage M36B1.)

The length of the 90mm gun necessitated a travel lock on the rear of the hull. Track blocks are stowed above the rear fenders, and a folding blanket rack for the crew is attached to the rear hull plate. (Picture from TM 9-748 90-mm Gun Motor Carriage M36B1.)

The hull hull floor was made up of the lids of 90mm ammunition boxes. Besides the 11 90mm rounds stowed in the turret bustle, a further 36 were stowed in the hull. (Picture from TM 9-748 90-mm Gun Motor Carriage M36B1.)

To release the travel lock, the spring release was pulled down and the gun was then elevated. Once free, the travel lock was latched to the rear deck. (Picture from TM 9-748 90-mm Gun Motor Carriage M36B1.)

The gun cradle was also provided with a lock, shown here in the open position. To release the cradle lock, the hand lever was pulled up, releasing the cradle lock body. The gun was then elevated to remove the lock from the cradle hook. (Picture from TM 9-748 90-mm Gun Motor Carriage M36B1.)

From this angle, it would be very difficult to differentiate this M36B2 from an M36. This vehicle is fitted with the folding turret roof armor which provided overhead protection while still allowing all-around vision. This vehicle has a muzzle brake, and the .50cal MG is stowed on the turret rear. In addition, it has been modified with the spaced-out suspension that allowed extended end connectors to also be mounted on the inner track run.

The cradle traveling lock is shown here in the locked position. The cradle lock could be operated from inside the turret and was therefore appropriate for use when the gun might be needed quickly. (Picture from TM 9-745 90-mm Gun Motor Carriage M36B2.)

The clutch lockout controls were peculiar to vehicles powered by the twin GM diesels. The lockouts held either or both engine clutches in the disengaged position so one or both engines could be started or used independently or disconnected from the propellor shaft without the driver keeping the clutch pedal pressed. The throttle lever was used to provide sufficient fuel to start and idle the engines, to control the engine speed when the vehicle was stationary, and when moved to the "NO-FUEL" position to stop fuel flow and therefore stop the engines. The throttle lock lever locked the throttle lever in whatever position it occupied. (Picture from TM 9-745 90-mm Gun Motor Carriage M36B2.)

The armored turret top consisted of a front section with hinged turret top doors and vision doors, and a rear shield. The vision doors were equipped with an angular adjustment to balance the need for vision and protection. (Picture from TM 9-745 90-mm Gun Motor Carriage M36B2.)
