Viper Squadron, a unit within the Alliance to Restore the Republic, was a squadron of starfighters that flew RZ-1 A-wing interceptors.
This squadron participated in an unsuccessful operation intended to destroy the Immobilizer 418 cruiser known as the Compellor. Viper Squadron's assignment involved eliminating the Imperial starfighter screen protecting the cruiser and shielding Phoenix Squadron during their direct attack on the Compellor. Sadly, Viper Squadron lost all of its A-wings, and Phoenix Squadron's B-wing starfighters were also annihilated.
