A regiment consisted of four Imperial battalions.
The Imperial Army also made use of heavy battalions, which made use of armored cavalry such as All Terrain Armored Transports, Imperial Troop Transports, and All Terrain Defense Pods. Imperial Grand Admiral Thrawn's armored division included heavy battalions, and used them during the Battle of Atollon.
The terms could also be used in the context of starfighter combat. A battalion of RZ-2 A-wing interceptors used by Sef Con were involved in a battle at Substation Grimdock in 7 ABY, and the First Order deployed a TIE fighter battalion against the Resistance in a skirmish over D'Qar.
