Comparing: VK 20.01 (D) vs. T-28 vs. Type 1 Chi-He

Prototype of a medium tank developed by Daimler-Benz from 1939 through 1941. The new vehicle was to become a new standard medium tank of the Wehrmacht. The prototype was deployed on the Eastern front. Combat testing revealed a number of serious faults. In 1941, the tank was deemed obsolete, and the project was discontinued.

The T-28 tank was developed by the Experimental Machine Design Bureau of the Voroshilov plant. The vehicle saw service on August 11, 1933. A total of 503 tanks were manufactured at the Leningrad Kirov Plant between 1933 and 1940. During mass production, the T-28 tank underwent a number of changes in design and modifications. The vehicles were used in the war with Finland in the winter of 1939–1940 and at the beginning of WWII.

The Type 1 Chi-He medium tank was a further development of the Type 97 Chi-Ha. It was developed in 1941, but due to the lack of steel, production did not start until 1943. A total of 170 tanks were manufactured. Most of them were held for the defense of Japan and never saw combat.
