Comparing: M2 Medium Tank vs. Vickers Medium Mk. III

The only medium tank to be adopted by the US Army during the interwar period. The vehicle was equipped with a 37 mm gun and six 7.62 mm machineguns, four of which were mounted on rotating fire units. The two non-rotating machineguns were placed on the front of the hull. Despite unimpressive combat characteristics, the M2A1 became a milestone for American tank development from the time of its inception by virtue of being easily adaptable for mass production. In 1940, 94 vehicles were produced.

British medium tank also known as the Vickers "16-tonners". Three prototypes were produced by Vickers from 1926 through 1931. According to some sources, three more tanks were manufactured in 1933 and remained in service through 1938 but never saw action.
