The Cronus Wing is a military force of the United Earth Directorate, specialized in air and space combat. It was present in the Koprulu Sector during the Brood Wars. It consisted a huge bulk of the UED Expeditionary Fleet, given the number of ships it operated and seemingly large enough to invade and defend multiple worlds. While it did have a significantly large ground force, much of its strength relied on air and space combat units.
The Cronus Wing had a major presence in the Koprulu Sector, occupying worlds as Korhal and Char. This Wing also had the task of enslaving and (unsuccessfully) defend the fledgling Overmind.
