Should I join the Army?

I'm only a 16 year old girl, but I just love JROTC so much in my school I'm considering on joining it when I graduate? I want to experience college though - a double major in Music and Political Science - but the college I want to go to (Texas Christian Un.) has a good ROTC program, I'm not sure how that would work out. I've always said I don't want to go into the military, I want to do NSA, but I also said that about JROTC and now I'm on my way to being Battalion Commander. If I did do Army, I would love to get into a career with Intelligence. I'm not sure what Army/Military is all about, but I love JROTC so much I just thought I should open that door for a looksy. Should I?
