Comparing: Vickers Medium Mk. III vs. Großtraktor - Krupp

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.

This experimental combat vehicle was developed by the Krupp company as a medium tank. By 1929, two prototypes were manufactured from non-armor steel. They underwent trials in the Soviet Union from 1930 through 1933. The trials revealed multiple faults, and the vehicle never saw service. However, the results of vehicle development were later used by German engineers.
