When I was a recruiter I never spoke with someone under 18 with out parents present or at least them knowing where the child was. Obvious exceptions of course at high schools. You need to do your homework and check out ROTC programs, talk with every branch before deciding on Marines. All the programs the Marine recruiters spoke of are the same for all branches.
They talked to you to put it in your head early, and don't get me wrong serving in the military is a honorable profession, just make sure it is what you want and the right choice for you.
