The SSh-36 was worn by Soviet soldiers in several campaigns of the late 1930s and 1940s, including the Khalkin Gol campaign against the Japanese in 1939 (giving it the nickname "Khalkingolka"), the Finnish Winter War of 1939–1940, the 1939 invasion of Poland, the 1940 invasions of the Baltic states and Bessarabia, and in World War II, or as it is known in Russia, the Great Patriotic War. It was also distributed to the Republican soldiers of the Spanish Civil War in conjunction with Soviet support of the Spanish government.
