The Munitionspanzer IV, was a German support vehicle used during World War II. Built from a modified Panzer IV chassis, Munitionspanzers had their turrets removed and were refitted to carry ammunition and supplies for troops. They had no primary guns and instead relied on gunner positions on the hull equipped with MG34s for defense. A specialized variant of the Munitionspanzer equipped with a crane, called the Munitionsschlepper, were used to transport and load the two ton shells used by the Karl-Gerät siege mortar during the eastern campaigns.
