Produced by Degtyaryov plant
The PTRD-41 (Russian: Противотанковое однозарядное ружьё образца 1941 года системы Дегтярёва, romanized: Protivotankovoye odnozaryadnoye ruzhyo obraztsa 1941 goda sistemy Degtyaryova, lit. 'Anti-tank single-shot gun pattern 1941, Degtyaryov system') is an anti-tank rifle that was produced and used from 1941 by the Soviet Red Army during World War II. It is a single-shot weapon which fires the 14.5×114 mm round, which was able to penetrate German tanks such as the Panzer III and early models of the Panzer IV. Although unable to penetrate the frontal armor of late-war German tanks, it could penetrate their thinner side and top armor at close ranges as well as thinly armored self-propelled guns and half-tracks.
