Comparing: T7 Combat Car vs. Cruiser Mk. III vs. Pz.Kpfw. I

Light wheeled caterpillar vehicle with machineguns, developed for the U.S. cavalry. The trials of the first prototype started in April 1937 and continued until 1939. However, the T7 was discontinued in favor of track-type vehicles.

The vehicle was developed on the basis of the M1931 Christie tanks, purchased by the British Army in 1936. The vehicle was intended to be a fast, lightly-armored breakthrough tank. The modified design was deemed successful and became the basis for other cruiser tanks. A total of 65 vehicles were built. They saw combat in France and North Africa in 1940–1941.

The Pz I Ausf. A was the first mass-produced German tank. In 1935 the design received an upgrade, including elongated hull and a more powerful engine. Mass production of this version, the Pz I Ausf. B, eventually totalled 675 tanks. The standard armament was weak, but some tanks were upgraded on the battlefield to mount 20-mm guns.
