Panzer - The crew of a Sturmgeschütz III Ausf. G (assault gun) pose for a photograph in late 1944 or early 1945, possibly in Kurland, East-Prussia.
StuG's were operated by four men (the fourth is probably the one taking the photo)
These both useful and cost-efficient vehicles (manufactured at 1/3 of the prize of a Tiger II) were designed to follow the advancing infantry and destroy enemy bunkers, pilboxes, and anti-tank guns, unlike the Panzers which were supposed to be leading the attack way ahead of the infantry units.
By the time this picture was taken Sturmgeschütze were mainly acting in the anti-tank role, battling the seemingly endless flow of Russian T-34 and American Sherman tanks attacking Germany.
The 9,500 StuG's produced during WWII were responsible for destroying more than 20,000 enemy tanks which amounts to a "kill ratio" of more than 2:1
