Unlike regular Imperial starfighter squadrons, Avenger Squadron was permitted to modify their TIE craft with advanced and expensive gadgets previously deployed only by Grand Admiral Demetrius Zaarin's experimental test units. This extra equipment included deflector shields, beam weapons—including jamming, tractor and decoy beams—and extra missile racks for increased warhead payload. However, except for the shields, those upgrades were only made available if and when the mission at hand called for a specific upgrade.
Initially, the standard starfighters employed by Avenger Squadron were modified TIE/IN interceptors with deflector shields, but other craft were also available to them.
Veterans of Avenger Squadron flew TIE Interceptors that were marked with double white vertical stripes on both lower wing panels, including the squadron commander's Interceptor—designated Avenger Leader—before receiving a TIE/ad starfighter—designated Avenger One—to lead the squadron with.
During the campaign into the Airam sector, the whole squadron was outfitted with the advanced TIE/ad—which came to be as TIE Avengers—previously only flown by their commander. Subsequently, Avenger Squadron usually exclusively flew the TIE/ad starfighters.
During her attempt to turn Corran Horn, Ysanne Isard offered Horn command of the unit. Appealing to his vanity, Isard proposed that Horn could lead the elite Imperial pilots against Rogue Squadron, but he was unswayed.
Behind the scenesEdit
The squadron was introduced with the Balance of Power expansion pack for the Star Wars: X-wing vs. TIE Fighter game. When playing the Imperial campaign, the upgraded Interceptors with shields and later the TIE Avengers provided the player with starfighters similarly powerful to Rebel Alliance craft, unlike regular TIE Fighters which possessed no shields and were easily destroyed by a few hits. This is similar to the various upgraded special craft which are made available to the player in the Star Wars: TIE Fighter game.
