"Skeleton 2 ... Lost. Skeleton Squadron is down. We've had too many losses."
AWACS Sky Keeper[1]

Skeleton Squadron, officially the 178th Tactical Fighter Squadron, was an Osean Air Defense Force unit assigned to the International Union Peacekeeping Force.[2] The squadron saw deployment in the Lighthouse War.


On May 30, 2019, Skeleton Squadron took part in Operation Dual Wielder, where its objective was to help secure air superiority in the airspace over the Chopinburg Rainforest.[1]

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.[1]
