I think the military can be a good way of seeing the world. But it will probably not make you that rich. It is not for people that dont want to move around either. With all the wars going on I told my son not to get into the military. Even though I spent 10 years in the Army, it was not for me.
I don't plan to get rich, but between their programs to pay off student debt and the almost complete lack of living expenses I ought to come out ahead. But, what I am really in it for is the job experience, since that is the only thing (other than a specialized degree or "networking") that means shit when applying for jobs.
And we still have a few years of Obama left, I don't expect to get thrown into another war for at least that long. And even then I intend to be one of the guys fixing planes on a secure base, not in the field tripping over mines and getting shot at by local police.
