Vixen was on Mar Sara at the start of the Great War. It transported the 417th Confederate Marine Platoon to Bunker Complex 3847 and flew cover for the platoon's mission to Oasis Station. A special receiver was installed on the dropship to help the platoon locate its objective. Vixen was recalled to aid the evacuation of Confederate forces from Mar Sara, leaving the 417th to escape the zerg on foot to Bunker Complex 3847.
