Panzer IV Ausf.J

Medium Tank is a Tank Variant particularly prevalent during World War II which represented a compromise between the mobility oriented Light Tank and the protection and armour protection oriented Heavy Tank. 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 Chi-Ha and the German Panzerkampfwagen 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 Centurion and later the Chieftain. Many of the medium tanks lines became what are called Main Battle Tank in most countries today.
