Gough

=biography= according to the E3 2000 demo, Geoff was serving on the Pillar of Autumn in 2552, which crash-landed on Halo. There Geoff and the rest of his squad where to infiltrate a Covenant held bunker. Geoff and two of his squadmates drove there on a warthog, geoff riding shotgun, while the other three members got there on foot.

Geoff and the rest of the squad broke into the bunker, but lost Segure in the process. He and Wang where tasked with guarding the entrance door to the bunker. When they wanted to help their sergeant, who got ambushed, the sergeant got killed. Geoff escaped in a ghost, while Wang covered him. Followed by two ghosts and banshees, his ghost got shot down, but he was just in time saved by the master chief. the two of them where the only surivors of the mission.

He most likely died when Halo was destroyed by the Master Chief.

=Trivia=
 * This demo was taken at the E3 2000. there could be changes in the movie, as the master chief never worked on such mission Geoff and his squad went on.
