Hi Peaches,
well nothing wrong for a younger guy to look at doing 2-4 years in the service.
I was 18 and my dad said it's the army or the streets

I was in for 3 years, and had a great time. Met alot of good people, grew up some, and went to germany for 2 years.
if he was in the AF Rotc, and has some college, he probably can go in as an E-2 or E-3, depends on how much college I think.
Army is great, but if he any brains, tell him to pick the air force or navy. at least in those services, you get to use your brain more.
Mabey air traffic controller. do 4-6 years, and get out, get a federal job.
happy holidays
todd
