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.[6] The most successful Soviet use of snipers during the Second World War was during their defensive stages (1941–1943)[citation needed], after which the advantage of defense shifted to the German side and German snipers became a real danger to the advancing Soviet forces.
