An Italian American NCO who becomes a living legend during the Battle of Guadalcanal (see below for details). From then on, his war experience includes not only combat, but also selling war bonds, training troops and sleeping with beautiful actresses.
He's the only enlisted Marine in WWII to have received both the Medal of Honor and the Navy Cross.
One-Man Army: in episode 2, he holds off 3,000 Japanese troops after his 15-men unit dwindles to just 2 other men. And note that the real man's actions are severely underplayed, as it would be impossible to tell them in just an hour (he really held his position for three days, on no food or sleep).
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?".
A sensitive and idealistic young man from a wealthy southern family who enlists despite his father's pleas. His character best exemplifies the horrific effects of wars on the human psyche.
Has the largest episode count of all the characters.
An officer in the US Marine Corps and the most decorated US Marine in history. Commanded the 1st Battalion of the 7th Marines (Basilone's unit) on Guadalcanal and the 1st Marine Regiment (Leckie's unit) on Peleliu.
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.
