The Jagdpanzer concept so popular in Germany during the latter part of WWII created a tank destroyer that was cheaper and quicker to build than a regular turreted tank. The Jagdpanzer IV (Sd.Kfz.162/1) armed with a 7.5cm PaK42 L/70 gun entered production in August 1944. Production eventually reached more than 900 of this vehicle that soon came to be known as ‘Guderian’s Duck’! The vehicle was based on the chassis and drive train of the Panzer IV tank, while the 7.5cm gun without a muzzle brake was mounted in a fixed superstructure. The 25.8-tonne vehicle was popular with its crews thanks to its potent armament, good mobility and low profile, especially in the defensive fighting that characterized the latter part of WWII. The Jagdpanzer IV L/70 saw combat on the Western and Eastern Fronts, with the greatest concentration of vehicles occurring in the Ardennes Offensive.
