You mean resident sailor. Marines don't have corpsmen or medic, the Navy furnishes those
Yeah, Marines have Docs. They're not Marines, but we love them, and while their name tapes do say "US NAVY", they're a step up from that. Anyway, I've met corpsmen that were pretty hardcore, I remember hearing a corpsmen with a high and tight once tell a marine that he looked like a (politically incorrect derogatory nickname for sailors) because he walked out of the barber shop with a low reg hair cut (it was one of those that were "regulation" but didn't remotely look like what a Marine should have).
