E. Grafton

E. Grafton is a marine on patrol in Mars City patrolling the area around Marine Command. He wears a helmet, heavy armor, and wields a standard issue machine gun.

He welcomes the player to his job when he talks to him, but then tells him he has to do his job. After the first invasion as the Doomguy approaches the console that is requesting an uplink, Grafton can be found on the three stairs dead. A spot of blood on his upper body implies that he met his unfortunate fate from a gunshot.
