Combat on the Russian Front

[Vartuoosi]

About those captured 76mm guns, here is something i found in Achtung Panzer:
"Vehicles of the Marder series were based on proven chassis of obsolete tanks, as well as on those of captured French tanks. They were armed with either German-made Rheinmetall-Borsig 75mm PaK 40 series anti-tank guns, or Soviet 76.2mm F-22 Model 1936 divisional field guns, which were captured in large numbers in the summer of 1941. The German 75mm gun was able to penetrate 116mm of armor at 0 degrees with armor-piercing ammunition at the distance of 1,000 meters. Captured Soviet guns were modified by Rheinmetall-Borsig and rechambered to accept the German 75mm PaK 40 ammunition. They could penetrate 108mm of armor at 0 degrees at a range of 1,000 meters using armor-piercing ammunition."
