Based on the chassis of the Panzer III tank, the Second World War German Sturmgeschütz series of assault guns was a successful range of armoured fighting vehicles. Originally intended as a mobile assault weapon for infantry support, the StuG was constantly modified and saw extensive use on all battlefronts as an assault gun and tank destroyer.
