NotesThe Sturmgeschütz IV was developed to supplement the supply of StuG IIIs which had been reduced due to allied bombing. Hitler had received reports about the effectiveness of the StuG III in action and wanted to build as many tank hunters as possible. The StuG IV had the same fighting compartment and superstructure associated with the StuG III Ausf G, except for an armoured cab provided for the driver. It was also armed with the excellent 75mm StuK 40 gun which was mounted in a Saukopfblend mount. Early versions had a roof mounted splinter shield to house an MG but in 1944 some models had a remote controlled MG and Nahverteidigungswaffe and the usual Schürzen armour. The StuG IV was used in the same manner as the StuG III and served on all major fronts.
