A battalion was a large military unit of ground troops. Both the Confederacy of Independent Systems and the Galactic Republic deployed battalions of troops during the Clone Wars. In the Stormtrooper Corps, a battalion consisted of four companies, giving one a total of 800 stormtroopers. 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.
