Captain A.C. Exeter was the captain of GFMC Task Force Herakles, and squad leader of Force One, which was stationed to guard and repair their warship, the GFS Tyr. Although Exeter was mortally wounded when the Ing ambushed the Galactic Federation Marine Corps landing site, the captain was able to send a distress signal after they left, although it did not make it through, due to heavy magnetic interference caused by the atmosphere of Aether. He also left a message on a data terminal that records what happened during the ambush, but he succumbed to his wounds before he could finish it. Exeter is found with his facemask cracked open, unlike the other soldiers.
