Model - the Jagdpanzer IV L/70 (A) Zwischenlosung was the last tank to enter service with the Wehrmacht in September 1944. This placed a Jagdpanzer IV turret on a Panzer IV chassis and then fitted it with a powerful 75 mm Pak 42 L/70 (A) gun which was arguably more powerful than even the 88 mm anti-aircraft gun.
