Miller was a spacetime marine in TSFP, who ran away from his team, and was promptly shot dead by Time Assassins (same as Jameson). He is killed when he charged the Time Assassins blockade when they tried to stop Cortez from reaching the Spacetime Marine HQ. However, at the end of the game, the Time Crystals were destroyed, meaning the Time Assassins never killed him in the first place. He uses Private Hicks' model.
