 I'm in the 11th grade, so if I was interested in joining the military, what advice would you give to me? I would say take the choice very seriously. It's an important choice. I didn't. I joined for eight years, and the recruiter loved me because he could send me wherever and any place he wanted, and he did. So it's one of the most important decisions a young person can make, so don't do it alone and don't take it lightly.
