91W
A medic
I was a Combat Medic in the Regular Army from 1998 to 2002, and then in the Army National Guard from 2002 - 2006. When I enlisted, the MOS was 91B, and it was actually called Combat Medic (and was exclusive to line units). With the reoorganisation the MOS was changed to 68W, which was now called Healthcare Specialist, and was no longer exclusive to line units.
In some countries a medic, but a more common term would be physician.
They're not supposed to. A medic is able to defend themselves and their patient(s), but cannot engage in an offencive manner.
91B20 is a US Army Medical Specialist (Combat Medic)
Yes, anyone including noncombatants that is participating in a war can be killed.
Same as any other job in the military. Go to a recruiter, score well enough on the ASVAB to qualify and tell your recruiter that you want to be a medic. Make sure it says medic (68W in the US army) on your contract.
This question is rather vague, but I'll answer it to the best of my ability. A medic who has recently graduated medic school (like the US Army Academy of Combat Medicine in Fort Sam Houston TX) is still called a medic. More experienced medics are usually called by the nickname 'Doc' after they've proved that they're proficient at medicine and considered a good soldier. There is a vague pecking order among medics in any given company or battalion. A company's most experienced medic is considered that company's senior medic and all the rest are junior medics. The senior medic in a company is usually a corporal or a sergeant. In a battalion there is usually a medic that works directly for the doctor or physician's assistant (referred to as a battalion surgeon) who usually holds the rank of staff sergeant or higher. This medic is referred to as the triage NCO. As I mentioned before, though, most medics in any context will just be called either Doc or their last name by the soldiers to which they are assigned.
Can't happen in the US Army. You get awarded a medal for finishing basic.
