Tierfon Rebel Outpost, also known as the Tierfon Rebel Base, was one of the many thousands of small outposts that the Alliance to Restore the Republic owned. A squadron known as the Tierfon Yellow Aces was based at Tierfon. One Hundred and fifty eight pilots were stationed at the base so the squadron could go on mission after mission, but the personnel would still be well rested. The hangar of the base had room for eight starfighters, which were usually X-wings, a light freighter such as a YT-1300 transport, and several airspeeders for use on the planet's surface.
