Tiger Squadron was a group of 4 Y-wing craft. This squadron was utilized by Airam Clan leader Ilay, who was also an Imperial collaborator.
During the time of the Galactic Civil War, Ilay started working together with Fleet Admiral Wooyou Senn of Task Force Vengeance. After the Ambush in the Cron Drift, she was aboard the Dreadnaught named Kala'din to conduct further negotiations. Tiger Squadron, along with T-wing Squadrons Cobalt Squadron and Crimson Squadron, were tasked with escorting her vessel. Tamaron, a rival Clan Leader, discovered her meeting location and dispatched X-wings from Rogue and B-wings from Green Squadron with the intention of capturing her.
Despite the presence of her escorts, as well as TIE Fighters, TIE Interceptors, and even Assault Gunboats from the Star Destroyer called Rage, the Rebels were successful in fending off the enemy fighters. They also managed to disable the Dreadnaught and provide assistance for the corvette Storm to board the vessel and apprehend Ilay.
