The Sturmgeschutz IV (StuG IV) (Sd.Kfz. 167), was a German assault gun variant of the Panzer IV used in the latter part of the Second World War. It was identical in role and concept to the highly successful StuG III assault gun variant of the Panzer III. Both StuG models were given an exclusively tank destroyer role in German formations and tactical planning in the last two years of the war, greatly augmenting the capability of the dwindling tank force available to the German army on the Eastern and Western fronts. The StuG IV became known as an effective tank killer, especially on the Eastern Front.
It had a four-man crew, and was issued mainly to infantry divisions:
- Commander in hull left rear
- Gunner in hull left center
- Loader in hull right rear
- Driver in hull left front
