Here we have Sarge, the gruff, regiment, and somewhat socipathic leader of the Red Team in Halo Reach.
Sarge is the only one of the Blood Gulch soldiers who takes the war (or training exercise) seriously. His hobbies include mechanics, fighting the blues, and hating Grif.
It's implied that he's been in the military for a very long time, since he's never heard of a car that doesn't have a gun on it, not to mention all his accumulated unused vacation days.
Sarge is skilled in mechanics, though his skill level and success fluctuates from flawed to almost revolutionarily genius.
"You just got Sarged!"
"I hope you brought your wallet, because the rent in hell get's paid in advance!"
"Dr. Sarge says take two barrels of this shotgun and call me when you're dead!"
"A priest, a rabbi, and Grif all walk into a bar, and I kill em!"
"My grandpappy didn't fight in the Industrial Revolution for nothing!"
"I've got a boner for murder!"
"The most environmentally friendly thing to do is kill every living thing you see!"
" I only drink the blood of my enemies. And occasionally a stawberry yoohoo. Or a sasparilla. Grenadine, straight from the can. Deeelicious. ...Oh occasionally I do enjoy a 'Sex on the Beach.' Or a pina colata. (singing) If you like pina colatas, hengh! Gettin' caught in the rain, hengh! And you're not in to yoga, engh! Grif just has half a brain, ungh."
"Glory glory to the Red Team! Glory glory to the Red Team! Glory glory to the Red Team! The Red Team marches on!"
