Snipers of the Soviet Union played an important role mainly on the Eastern Front of World War II, apart from other preceding and subsequent conflicts. In World War II, Soviet snipers used the 7.62×54mmR rifle cartridge with light, heavy, armour-piercing (B-30), armour-piercing-incendiary (B-32), zeroing-and-incendiary (P3), and tracer bullets. Most Soviet World War II snipers carried a combat load of 120 rifle cartridges in the field. Unlike the militaries of other nations, these snipers could be men or women. In 1943, there were over 2,000 women functioning in this role.
In 1932, the "sharpshooters' movement" started under the supervision of the Kliment Voroshilov. In 1938, Red Army snipers took part in the Battle of Lake Khasan against troops of the Imperial Japanese Army The most successful Soviet use of snipers during the second world war was during their defensive stages (1941–1943), after which the advantage of defense shifted to the German side and German snipers became a real danger to the advancing Soviets.
Soviet and Soviet-derived military doctrines include squad-level snipers, which may be called "sharpshooters" or "designated marksmen" in other doctrines (see the "Sniper" article). They do so because the long-range engagement ability was lost to ordinary troops when submachine guns (which are optimized for close-range, rapid-fire combat) were adopted.
Soviet military doctrine used snipers for providing long-distance suppressive fire and for eliminating targets of opportunity, especially leaders, because during World War II, Soviet military leaders and combat theorists (Vassili Zaitsev contributed greatly to Soviet sniper doctrine, although he was officially neither of these) found that military organisations have difficulty replacing experienced non-commissioned officers and field officers during times of war. They found that the more expensive and less rugged sniper rifles could match the cost-effectiveness of a cheaper assault rifle given good personnel selection, training, and adherence to doctrine. The Soviet Union used women for sniping duties, including Lyudmila Pavlichenko and Nina Lobkovskaya.
