WThe Christie M1931, known as the Combat Car, T1 in US Cavalry use and Medium Tank, Convertible, T3 in Infantry branch, was a wheel-to-track tank designed by J. Walter Christie for the United States Army using Christie's ideas of an aero-engine and the novel Christie suspension to give high mobility.
WThe M1 Combat Car, officially Light Tank, M1, was a light tank used by the U.S. Cavalry in the late 1930s and developed at the same time as the infantry's very similar M2 light tank. After the Spanish Civil War, most armies,, realized that they needed tanks armed with cannons, not merely vehicles armed with machine guns, and so the M1 became obsolete.
WThe M2 light tank, officially Light Tank, M2, was an American pre–World War II light tank which saw limited use during World War II. The most common model, the M2A4, was equipped with one 37 mm (1.5 in) M5 gun and five .30 cal M1919 Browning machine guns.
WThe Mark VIII tank also known as the Liberty or The International was a British-American tank design of the First World War intended to overcome the limitations of the earlier British designs and be a collaborative effort to equip France, the UK and the US with a single heavy tank design.
WThe Medium Tank M1921 was a medium tank built in the United States in the inter-war period. In design, it was similar to earlier WW1 era tanks. United States Army engineers worked on the design of the tank, with some influence from British designs of the period, and from the earlier war experience. One example was produced. The tank was an early example of a turreted US tank, less usual at the time, with the turret housing the main gun, with the tank also possessing two machine guns for defence.
WThe Medium Tank M1922 was an inter-war period medium tank built in the United States. It was largely a variant of the Medium Tank M1921, with some changes to use the same track suspension system that had been developed for the Medium Mark D.
WThe Light Tank, T1 was a United States Army light tank of the late 1920s and early 1930s that was only built in prototype form. The tank was an Army design built by James Cunningham, Son and Company. Introduced in 1927, it was developed up through 1932 as a series of modified versions. The tank was never mass-produced, nor was it ever used in combat.
WThe T2 Medium Tank was an American design that replaced three prototype medium tank designs started in the 1920s for an experiment conducted by the United States Army. The T2 tank never saw combat nor left prototype stages and due to lack of funds was not mass-produced with only one built in 1930 by Rock Island Arsenal. Its legacy, however, was the M2 light tank, developed into the M2 medium, and onto the M3 Lee and M4 Sherman medium tanks.
WT7 Combat Car was a prototype United States light tank design of the interwar period. It could run on rubber-tired wheels on roads or mount tracks for cross-country use. Although adequate in some areas, it lacked armament compared to contemporary vehicles and the project was cancelled after only one was built.
