Sector Army

A Sector Army, also referred to as a battle army, was a large army formation that was used by the Galactic Republic during the Clone Wars. The Grand Army of the Republic had twenty Sector Armies, each with an accompanying Republic Navy numbered fleet, such as the 2nd Fleet. Two Sector Armies composed a single Systems Army, which was led by a High Jedi General.

A Sector Army consisted of four corps, totaling a standard 147,456 clone troopers. In turn, a corps would be composed of sixteen regiments. Sector Armies from the 1st Sector Army to the 6th Sector Army, including the 4th Sector Army, served in the Grand Army as reserve commands. The 7th Sector Army and the 8th Sector Army through the 12th Sector Army served in the northern quadrant of the galaxy, while the remaining eight Sector Armies served in the southern quadrant.

During the First Battle of Geonosis, the Republic sent two full battle armies to Geonosis, with Master of the Order Mace Windu commanding one army in one front, and Grand Master Yoda leading another, both totaling 294,912 troopers of which 192,000 of which were deployed in battle. The Galactic Republic commissioned twenty Haven-class medical stations for the war effort, each being attached to a Sector Army.
