A Philadelphia native who puts his career as a sports writer on hold in order to to enlist in the Marines. He's The Everyman of the series - just your average American guy who likes beer and girls, fits in well with similarly fun-loving comrades, and tries to survive the war without losing his sanity.
Back for the Finale: he's absent for 3 episodes after being wounded at Peleliu, and reappears only in episode 10.
"We're all sent here to kill Japs, weren't we? So what the hell difference does it make what weapon we use?".

The Men First: Discussed. When his squad start complaining about being sent on patrol in Okinawa, he points out that he plans on going with them. Throughout the series, he's always with his comrades during battle.
A member of K Company's mortar squad along with Sledge. He's a seasoned veteran by the time the latter gets into combat and is thus able to show Sledge the ropes.
On a side note, he's Cajun, and it shows.
Creepy Awesome: he bullies newcomers, pries golden teeth out of dead Japanese soldiers' mouths and amuses himself by throwing pebbles into their blown-open heads. It's unnerving as hell, but fascinating to watch.
Dissonant Serenity: he's casual and nonchalant whether he's fighting, vomiting from seasickness, or hunting for war trophies.
Dysfunction Junction: it's implied that his family (if he even has any left) is not particularly loving.
