==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 (17th-18th centuries), sotnyks were leaders of territorial administrative subdivisions called sotnyas. Such sotnyks were subordinated to polkovnyks (colonel) who were in control of a polk (primary administrative division) and a regiment (military unit).
