PTRD-41

The PTRD-41 (Shortened from Russian, ProtivoTankovoye Ruzhyo Degtyaryova; Противотанковое однозарядное ружьё системы Дегтярёва образца 1941 года; "Degtyaryov Single Shot Anti-Tank Weapon System Model of 1941") was an anti-tank rifle produced and used from early 1941 by the Soviet Red Army during World War II. It was a single-shot weapon which fired a 14.5×114 mm round. Although unable to penetrate the frontal armor of German tanks, it could penetrate the thinner sides of early-war German tanks as well as thinly armored self-propelled guns and half-tracks.
