This guy may look like someone out of a Hollywood war movie, but he's no actor - he's the real deal. Gung-Ho has more guts than sense. He has no problem walking through a fierce COBRA artillery barrage just to get a better look at his target. Sound crazy? Maybe, but when it comes to describing the terms bravery, courage, and determination, Gung-Ho is the perfect example. His "esprit de corps" attitude and drive to be the best keeps him and his fellow G. I. Joes on their toes, ready to go into battle when called. He's so keyed up all the time that the only way he unwinds is when he and Leatherneck get liberty to go out and compare notes with the Navy S.E.A.L.S. The funny thing is that their version of winding down usually results in heated outbursts with their Naval counterparts. What do you expect? They're Marines through and through.
He's all Marine . . . tough, bull-headed, and always on the offensive. Leatherneck has never been in a situation where defeat was an option. When he was a Boot at Camp Lejeune, he was so revved up to complete the training that he would awaken his drill sergeant and the men in his barracks before the bugler blew reveille at 4:30 AM. That didn't win him any popularity contests with his fellow Boots, but they soon realized that he was more of a jarhead than all of them combined.
Before joining the G. I. Joe Team, Leatherneck served with a variety of Marine units throughout the world. He earned a reputation for being one of the roughest, hard-nosed brawlers in the Corps, ready to fight to the hilt for a fellow Marine. Aside from that, the only other soft spot this guy has is on the top of his head, exactly where his mother accidentally dropped him as a baby. That would explain his overbearing, opinionated disposition.
