The T55E1 3-inch gun motor carriage was a prototype vehicle developed by the Allied Machinery Manufacturing Company in 1943 for the US Army. An eight-wheel drive vehicle, the T55E1 was armed with one three-inch gun in a limited traverse mounting and a supporting .50 caliber machine gun.

Development

Cook Brothers had developed an unusual vehicle for desert conditions. This had two four-wheel-drive bogies each with its own engine. Steering was by pivoting the front bogie. They then developed their design into a tank destroyer with two engines at the rear. There was sufficient interest from the Army for a contract for development as the T55. Testing led to modifications to the pilot as the T55E1. Further testing confirmed that it was not suitable and the T55E1 was cancelled.

Power was from two Cadillac eight-cylinder water-cooled engines. Production began in 1943, however by this time preference had shifted to tracked anti-tank vehicles, and the T55E1 was cancelled.

The M4 Sherman, officially medium tank, M4, was the most widely used medium tank by the United States and Western Allies in World War II. The M4 Sherman proved to be reliable, relatively cheap to produce, and available in great numbers. It was also the basis of several other armored fighting vehicles including self-propelled artillery, tank destroyers, and armored recovery vehicles. Tens of thousands were distributed through the Lend-Lease program to the British Commonwealth and Soviet Union. The tank was named by the British after the American Civil War General William Tecumseh Sherman.

<span class="mw-page-title-main">Continuous track</span> System of vehicle propulsion

Continuous track or tracked treads are a system of vehicle propulsion used in tracked vehicles, running on a continuous band of treads or track plates driven by two or more wheels. The large surface area of the tracks distributes the weight of the vehicle better than steel or rubber tyres on an equivalent vehicle, enabling continuous tracked vehicles to traverse soft ground with less likelihood of becoming stuck due to sinking.

The Type 94 tankette was a tankette used by the Imperial Japanese Army in the Second Sino-Japanese War, at Nomonhan against the Soviet Union, and in World War II. Although tankettes were often used as ammunition tractors, and general infantry support, they were designed for reconnaissance, and not for direct combat. The lightweight Type 94 proved effective in China as the Chinese National Revolutionary Army had only three tank battalions to oppose them, and those tank battalions were equipped only with some British export models and Italian CV-33 tankettes. As with nearly all tankettes built in the 1920s and 1930s, they had thin armor that could be penetrated by .50 caliber (12.7 mm) machine gun fire at 600 yards (550 m) range.

The M10 tank destroyer, also known as 3-inch gun motor carriage M10 or M10 GMC, was an American tank destroyer of World War II. After US entry into World War II and the formation of the Tank Destroyer Force, a suitable vehicle was needed to equip the new battalions. By November 1941, the Army requested a vehicle with a gun in a fully rotating turret after other interim models were criticized for being too poorly designed. The prototype of the M10 was conceived in early 1942 and delivered in April that year. After appropriate changes to the hull and turret were made, the modified version was selected for production in June 1942 as the "3-inch Gun Motor Carriage M10". It mounted the 3-inch gun M7 in a rotating turret on a modified M4 Sherman tank chassis.
