First of all, military with honorable discharge looks great on any resume, so that's always a plus.
Jobs - Cop (police) - the military will definitely train you for this position. I was in the Air Force and several of the enlistees I knew went into Tech School for police officers. I believe it was an 8 week school, but I'm not 100% positive.
Psychiatrist - I'd suggest learning to spell this first! (LOL) Anyways, in the outside world, you would need a degree to be a psychiatrist. This is likely the same scenario in the military. Not only that, there is likely less military job openings for such a field. Not saying that you can't or won't be a psychiatrist in the military, just saying that the requirements are going to be much more stringent.
As for dying - like one of the other individuals (who obviously hates the military) said, if you join the Army you are likely to get deployed. ANY military branch you are likely to be deployed. However, if death is a concern, the Air Force and perhaps Navy would be a better option for you since they aren't ground-pounders. Army and Marines both have a hidden MOS of infantry. The recruiters will sign you up for a job such as policeman, for example, but leave out the part where you will ALSO train for infantry. So keep that in mind.
People in the military die, but so do people who live in America. Traffic accidents, crime, drugs, etc. you are not suddenly in peril BECAUSE you joined the military, you are simply more acutely aware of it. But if you survive the military, you can pursue your education (tuition assistance, GI Bill) during or after your service.
PS. I don't know what venus is smoking, but the ones doing the most fighting are ARMY and MARINES, not NAVY. AIR FORCE sends their fighters (officers) out on jets, so no problem there. I have been to Iraq and I am a veteran, I'm guessing she wasn't.
