四號坦克
Although slow, production of the Panzer IV had continued; by the end of 1940 386 Ausf. D models were in service and in 1941 a further 480 were produced, despite an order from the army for 2,200. The short L/24 gun was the main advantage of the Panzer IV; the weight and armor of early models were close to that of the Panzer III.
