Aggressor Wing was a unit of BTL-S3 Y-wing starfighters belonging to the New Republic. It was under the leadership of Colonel Horton Salm in the time following the Battle of Endor. Telsij Cayr and Kin Kian were among its other members.
To stop the Imperials from plundering Brentaal IV before the Battle of Brentaal, Aggressor Wing was charged with slowing down their withdrawal. Following this operation, Salm received a promotion to the rank of General.
Later, the Aggressors played a vital role in the liberating of Sate Pestage from Ciutric IV by Commando Team One. They then went back to the battlefield to rescue Rogue Squadron from attacks launched by the Empire.
