First Alliance-PLANT War
Battle of Orbit
Duane Halberton was the commander of the Earth Alliance's 8th Fleet and also the primary supporter of the G Project that constructed the Archangel and EA's "GAT-X series" mobile suits. He commanded the 8th Fleet from the flagship, Agamemnon-class warship Menelaos. It was revealed that Murrue Ramius was Halberton's student. He has sympathy towards coordinators, especially Kira Yamato when he was amazed by their sheer abilities. Halberton and his fleet made their primary objective to protect the Archangel's descent to JOSH-A, Alaska from ZAFT forces led by Rau Le Creuset, which resulted in his demise and the destruction of the 8th Fleet.
