PTRD

ProtivoTankovoye Ruzhyo Degtyaryova 1941 (PTRD-41) was an anti-tank rifle developed and produced in the early 1941 by the USSR. Designed based on the Polish Model 35 anti-tank rifles the Red Army captured, and with some reference design to the German PzB38/39. When compared to the German counterpart the PzB39, PTRD is significantly heavier, significantly longer and often require a two man crew to operate. Prone to jamming more frequently but have a better armor piercing performance, PTRD was also produced in a much lower quantity than the German PzB39. The PTRD and it's later developed semi-automatic version PTRS-41 are designed to chamber the 14.5×114mm B-32/BS-41 round. The armor-piercing performance of the PTRD is considered stronger than it's predecessor counterparts, able to achieve a bullet muzzle velocity of 1,012m/s, able to penetrate an armor plate up to 35 to 40mm thick at a distance of 100 meters at 0 degrees. Theoretically effective against the side and rear armor of the German Panzer II, III, IV and early models of the Panthers. However, due to the high velocity and small size of the round, it had a very high chance of shattering and/or ricocheting, especially if the target was struck at an oblique angle.
