Tracy Rhys served as a Sergeant in the Free Worlds League Military prior to the Jihad. Rhys was recognised as a hero for her role in the assault on the Word of Blake Space Defense System complex at Rio during the liberation of Terra.
Rhys' reputation grew further when, now serving as a Major in the coalition forces, Rhys led two battalions of Battle Armor troops in a six-hour battle to capture the Lowyfur, the last active Wyrm-class submersible SDS platform on Terra. Rhys' and her troops were deployed onto the Lowyfur by rapid drop from Aurora-class DropShips after a team of Ghurka commandos executed a daring HALO drop onto the Lowyfur when it surfaced amidst a storm in the North Sea to re-air. The surviving Ghurkhas stormed the bridge of the Lowyfur, delaying it from submerging long enough for Rhys and her troopers to deploy. The Lowyfur was cleared one deck at a time in a fierce close-quarter battle, with Rhys' finally declaring the Lowyfur cleared and captured 3,000 meters below the surface of the North Sea on the 12th of February 3080.
