In 1932, the "sharpshooters' movement" started under the supervision of 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 Soviet forces.
