The term troop was used to denote relatively small military formations of platoon or company size, usually being used as an alternative to these terms with mobile or elite forces. In the Grand Army of the Republic, it denoted a platoon-strength unit in the Special Operations Brigade, a group of 20 clone commandos organized in five squads, with five such 20-man troops forming a company. In the Imperial Army, however, the term troop was applied instead to a company-strength scout unit, consisting of four platoons, with a total of and 116 infantry and forty scout troopers.
