Grez Squadron was a squadron of Rebel Alliance Y-wing starfighters. They launched from the Nebulon-B2 frigate Colada during an attack by Imperial II-class Star Destroyer Rage on the Airam-owned supply platform in the Goff system.
Following the lead taken by Azul Squadron, the ships of Grez selected Interdictor Compellor as their primary target, attacking it with proton torpedoes. Alert to their adversaries, the attacking Imperial forces, with the modified TIE/IN interceptors of Avenger Squadron in the vanguard, made short work of the lumbering Y-wings. The Compellor was saved from destruction.
