The Lion, a Nebulon-B2 frigate, served the Rebel Alliance. This vessel, in conjunction with the Lance and the Ornik, was slated to initiate an assault against the Imperial-class Star Destroyer named Conqueror. Fighter support was provided by T-65 X-wing starfighters, RZ-1 A-wing interceptors, and B-wing starfighters, while BTL Y-wing starfighters acted as a reserve force. The Conqueror deployed TIE Avengers from Avenger Squadron, alongside TIE/IN interceptors and TIE/sa bombers.
The destruction of the Conqueror cannot be considered canon, regardless of the player's choices, since it participates in, and is destroyed in, a separate engagement.
