Skeleton Squadron, officially the 178th Tactical Fighter Squadron, was an Osean Air Defense Force unit assigned to the International Union Peacekeeping Force. The squadron saw deployment in the Lighthouse War.
The mission was almost a success until Erusea deployed an Arsenal Bird to quickly regain control of the region. Skeleton 1 was shot down, forcing AWACS Sky Keeper to delegate command of the squadron to Skeleton 2. The rest of the unit was later shot down when the Arsenal Bird deployed its Microwave Powered Dome.
