While the StuG was considered self-propelled artillery, it was not clear which land combat arm of the German Army would handle the new weapon. The "Panzerwaffe" (armoured corps), the natural user of tracked fighting vehicles, had no resources to spare for the formation of StuG units and neither did the infantry. It was agreed that it would best be employed as part of the artillery arm. The StuGs were organized into battalions (later renamed "brigades" for disinformation purposes) and followed their own doctrine. Infantry support using direct fire was its intended role. Later, there was also a strong emphasis on its use as an anti-tank gun.
