The Rebel Alliance utilized a MC80 Star Cruiser known as the Chie.
A group of Strike-class medium cruisers, specifically the Longbow squadron, launched an assault on it. They received support from Avenger Squadron piloting TIE/ad starfighters along with Assault Gunboats. The cruiser itself was defended by X-wings from Rogue Squadron, as well as B-wings and A-wings.
