You're 16. Why ask about something that's not going to happen for maybe 20 years? How do you know you'll need/want to go to school? You might have gained all the best schooling you need from the military or in your spare time?
I can tell you from experience of college pre-military, post-miltary and then a career change a decade after that, is my life experiences enriched my college experiences.
I'll also tell how it feels to be paying off a Master's degree that I'm not using... Do not assume you'll need a university degree to go places in the civilian world. If I had to make the choice all over again, I would have chosen blue collar work, made more and felt the satisfaction of productivity.
