Would this conflict me to become a Marine?

Corpsmen do not go through the same training, but they are the best human beings on the face of the planet. Some of their training gets harsh. I happened to run the Naval Corpsman Stretcher Course at Camp Johnson, NC while in the Corps. It was sick! There is not a single more motivated individual on the face of the planet than a Naval Corpsman serving with the Corps. I really hate to tell you this, but enlistment does not sound good for you. But no matter how much advice you get here, simply go to the source. Talk to both the Navy and the Marines and find out for sure.
