Sotnik
Sotnik or Sotnyk was a military rank among the Cossack starshyna, Strelets Troops in Muscovy and Imperial Cossack cavalry, the Ukrainian Insurgent Army, the Ukrainian Galician Army, and the Ukrainian People's Army.Military ranks
The word sotnik literally means commander of a hundred men in most Slavonic languages. In the Russian rank-structure the military role of a sotnik developed into that of a poruchik, eventually known as "lieutenant". Ukrainian military formations retained the rank of sotnyk well into the 20th century as the equivalent of an army captain.
The rank did not officially change, but rather fell out of use after the Soviet Army and intelligence services suppressed the Ukrainian Insurgent Army in the late 1940s and 1950s.
Some translations render the word sotnik as "Captain", however the "Lieutenant" interpretation also appears in common usage, and for the sake of historical and social clarity the original rank-name is used.Administrative rank
Holders of the rank also served as leaders of territorial units. In the Cossacks' paramilitary society of the Zaporozhian Host, Cossack Hetmanate, and Sloboda Ukraine, territories were organized along the lines of military organization and commanded by officers. During the Khmelnytsky Uprising and in the Cossack Hetmanate, sotnyks were leaders of territorial administrative subdivisions called sotnyas. Such sotnyks were subordinated to polkovnyks who were in control of a polk and a regiment.
