There's no such thing as a safe/non-dangerous job in any branch of the military. Just google "coast guard iraq" or "national guard iraq." Also see this page.

I could probably make close to that living at home (you probably already are), while getting to keep most body parts.[/quote]
I know there are no truly safe jobs in the military. However, there are jobs that are as statistically as dangerous as driving a car. I don't mean that every MOS in the Coast Guard, Navy and Air Force is not dangerous, or will not result in dangerous deployments. I am friends with a man who took 5 deployments to Iraq with the Air Force. He has seen more combat that most of the men and women I know from the Army. The National Guard can be extremely dangerous, and even more so than Active Duty units, because of less training, loosely enforced PT standards, and second rate equipment. I know this better than most, because my father is the Chief of the Joint Staffs for the MA National Guard. Every MOS that is represented in the Active Duty Army is also in the Guard and Reserves, and many of today's front line troops are drawn from them. This, combined with less choice in MOS is why I didn't mention them.
These asides there are certain jobs that will not expose you to enemy action as much or as readily. These jobs are a great way to learn a good trade, earn money for college, save money, and just survive in a world where jobs are hard to come by. On the other hand, you could join up, serve your tour, fight, maybe die and maybe be maimed and crippled for your country. It's not for everybody.
