- "The Wheel's sanctuary is a courtesy of the Empire. As the Empire's chief representative in this sector, I elect to withdraw that courtesy-- until our troopers find and slay every being on that freighter!"
- ―Sector Commander Zertik Strom
Sector Commander was a title held by Imperial personnel responsible for the military forces in a sector. Eventually, as the Rebel Alliance grew in power, its leadership appointed sector commanders in liberated areas.
An average sector commander in the Empire had one or more Super Star Destroyers as part of his or her military assets. A sector commander was one of the top-ranking officers allowed a full Imperial Order of Battle. Zertik Strom was a sector commander of the military forces in the sector containing the Besh Gorgon system and the Wheel. At some point, the Alliance to Restore the Republic began to appoint sector commanders in regions of space that they controlled. One such commander was Callus, who oversaw the Mortex sector.
