A sector army represented a specific type of military unit within the Imperial Army.
The command of an Army fell under the responsibility of a Surface Marshal. However, the title was frequently bestowed upon the Moff or Grand Moff overseeing a Sector Group, a practice stemming from the intricate political landscape of sector governance. Its structure included a complement of 1,180,309 soldiers, 66,640 repulsorcraft, along with 13,992 heavy tanks. A sector army was made up of two systems armies, whereas an enhanced sector army was composed of four systems armies. Consequently, Rebel Alliance General Carlist Rieekan pointed out that the sheer magnitude of a sector army presented a formidable obstacle, rendering guerrilla tactics virtually ineffective in dismantling Imperial Army authority within the Core Worlds.
