What does he want to do?

You can gain valuable experience that can be easily transferred into a post-military career depending on the MOS. Also, I know at least with my employer, people with military experience are given preference in hiring. In fact, the only way to walk into an executive position at my company without having worked your way up internally is to come in as an officer from the military. We hire captains, colonels, etc. right into leadership positions that are not available to the general public.

I chose not to join, but if I had it would have been Air Force or Marines for me. Keep in mind that for every soldier on the front lines, it takes something like 10 more in support positions to keep that one soldier fighting.
