A PzKpfw IV Ausf. F2 belonging to the 12th Panzer Division in the Volkhov's pocket, Northern Russia, photo taken between March and November 1942. In this photo we can see two of the main characteristics that allow to distinguish between a Ausf. F2 and later variants of the Pz IV: The single baffle muzzle brake, unique to the F2 and the turret side vision ports (above the n. 631) that were absent in later variants, the exception being a couple of Ausf. G's that were fitted with excedent F2 turrets in times of need.
