Sturmgeschutz, abbreviated StuG, was the weapon of the Strumartillerie, the branch of the German Artillery tasked with close fire support of infantry. StuGs were very successful in their intended support role and destroyed, among others, many bunkers, pillboxes, and other defenses. The StuG is not generally considered to be a true tank because it lacks a turret. The gun was mounted directly in a casemate-style fashion, with as low a profile as was possible to reduce vehicle height, and had a limited lateral traverse. Omitting the turret made production simpler and less costly, enabling greater numbers to be built. By late 1943, improved Allied tanks and tank destroyers with improved guns, rotating turrets, and superior mobility forced the StuG into being primarily an ambush weapon. From December of 1943 to March of 1945, 1139 were produced by Krupp at Magdeburg. StuG IV (Sd.Kfz.167) was armed with a 75mm StuK 40L/48 gun mounted in a cast version of “saukopf” mantlet.
