As in an actual doctor, or a Combat Medic (Combat Medics are informally referred to as "doc" by other soldiers in their unit, although they're not doctors). For the former, go to medical school, pass, join the Army. For the latter, enlist for the 68W (Healthcare Specialist) MOS, and complete your Basic Combat Training and Advanced Individual Training. A particular note of warning if you're looking to get into the latter, from someone who has been there - you'd better be 100% sure this occupation is what you want. Serve in a line unit which deploys to a hostile environment, and you'll have to be able to accept that you probably won't have a 100% success rate, and you will lose patients. Working in a civilian EMS, it's much easier to keep yourself disconnected - much different story for a Combat Medic.
