Armoured companion (Polish: Towarzysz pancerny Polish: [tɔˈvaʐɨʂ panˈtsɛrnɨ], plural: towarzysze pancerni) was a medium-cavalryman in 16th to 18th century Poland, named after their chainmail armor. These units were the second-most-important (and successful) cavalry in the Polish-Lithuanian army, after the hussars. Most pancerni were recruited from the middle or lower classes of the Polish (or Lithuanian) nobility. They were organized into companies, with each company (Polish: chorągiew or rota) consisting of 60 to 200 horsemen.
