This is a Plastic Soldier Sturmgeschütz III Ausf. G Assault Gun. These kits are intended for the wargaming market and come packaged three kits to a box. I built this one to represent a StuG III on the Russian Front during 1943 / 44. I replaced the overly-thick Schürzen which also helps hide the rather basic running gear and added various other details to spruce it up a bit. The commander figure is included with the kit.
