Sarge is the leader of the Red Eagles in RvB: The Blood Gulch Saints
Sarge was born into the military. Literally. During the battle of Harvest, after he was born in his parents house, a team of Elites broke in and killed his parents. Then some UNSC soldiers killed the Elites and saved Sarges life. He was then in the military until the day he recieved the Medal of Honor. He was thrown in jail for not revealing his name. Eventually he broke out, got together with a mechanic he met in the army, and started the Red Eagles in the Town of Blood Gulch.
