If i want to be a combat medical what classes do i have to take in college

Often times combat medics are enlisted personnel trained in first aid (this means you can join after high-school and all your education will be given to you through training). Military doctors and nurses are college educated however, and perform more of a typical role of ‘doctor’ than a combat medic (they will often operate out of a hospital or clinic rather than in a squad or platoon while in the theatre of war.)
