The Atrivis Sector Force was the name given to the Atrivis Resistance Group after it joined the Alliance to Restore the Republic during the Galactic Civil War. The unit was placed under the command of the Alliance Sector Command, as the renaming made the unit an officially recognized Sector Force. It was later reorganized as a New Republic Sector Fleet. Most of the fleet supply depots were located on Generis. They were lost during the Thrawn campaign.
