StugIIIF 7.5cmL/48 (block mantlet)

The Sturmgeschütz III (StuG III) assault gun was Germany’s most produced armoured fighting vehicle during World War II. It was built on the chassis of the Panzer III tank. Initially intended as a mobile, armoured light gun for infantry support, the StuG was continually modified and was widely employed as a tank destroyer.
The StuG IIIF represented the first real upgunning of the StuG, using the longer 7.5 cm StuK 40L/43 gun. This change marked the StuG as being more of a tank destroyer than an infantry support vehicle. Side hull skirts were added to some F models for protection from Soviet anti-tank rifles; although these skirts were far more common on the later ausf G.
