He was born in Wyoming. He has a large scar on his face that he got from a bar fight. A short flashback in Brothers in Arms Earned in Blood shows the actual fight. He was married and had a daughter shortly before becoming a member of the 101st Airborne Division. He was assigned to 3rd squad, under Matt Baker.
In Brothers in Arms: Road to Hill 30 he is leading Baker's Fire Team throughout the game. He believes that he should be leading instead of Baker. At the end of the game he is promoted and will be leading 2nd squad.
In Brothers in Arms: Earned in Blood you play as Red. Now, in charge of his own squad, Red learns how hard it really is to lead men into battle. During a battle the tip of his ring finger is shot off by a German soldier. Through each of their experiences Red and Baker become closer now that Red understands what Baker had gone through with the loss of each man.
In Brothers in Arms: Hells Highway Red plays a supporting role, assisting Baker throughout the game. Red misses his wife and daughter very much, and is desperate to get back to them. As Baker's hallucinations get worse, Red starts wondering if it will limit him to fulfill his duties as squad leader and confronts him about it. While arguing with baker in a cafe, the building is hit by a mortar round. The explosion kills Friar, injures Campbell, gives Baker a large scar on his face, and paralyzes Hartsock. Since red is paralyzed now and being sent home, Baker chooses Paddock to replace him as 2nd Squad leader.
