Medium tank Medium tank Medium tank is a classification of tanks, particularly prevalent during World War II which represented a compromise between the mobility oriented light tanks and the armour and armament oriented heavy tanks. The most widely produced, cost effective and successful tanks of World War II (the Soviet T-34, the American Sherman tank, the Japanese Type 97 and the German Panzer IV) were all medium tank designs, and the success of the concept would later lead to the development of later generations of medium tanks such as the Chieftain. Many of the medium tanks lines became what are called main
Japanese tanks of World War II final defense of the Japanese home islands against the expected Allied invasions. However, the project was abandoned to free up manpower and critical resources to concentrate on the development and production of the more practical Type 4 Chi-To medium tank. As with many innovative weapons projects launched by Japan in the final months of World War II, production could not advance due to material shortages, and the loss of Japan's industrial infrastructure to the allied bombing of Japan. With the end of the Pacific War, an incomplete Type 5 prototype was seized by American forces during the occupation of Japan.
