A Cossack host (Ukrainian: козацьке військо, romanized: kozatske viisko; Russian: каза́чье во́йско, kazachye voysko), sometimes translated as Cossack army, was an administrative subdivision of Cossacks in the Russian Empire. Earlier the term voysko (host, in a sense as a doublet of guest) referred to Cossack organizations in their historical territories, most notable being the Zaporozhian Host of Zaporozhian Cossacks.
