Don't listen to @Nihonjin1051 Join the USAF instead, they have air-conditioned offices and a golf course on most bases. Actually though, do listen to Nihonjin and serve your nation, with your knowledge at such a young age, you will be a great asset to the US military and will learn skills that will help you for the rest of your life.
ha ha ha! You know me, man. Navy all the way.
On a serious note tho, young Mr. @AMDR , you are a citizen of one of the greatest nations in the earth. You have at your disposal many resources and opportunities. If you do decide to join the Armed Forces, be it Air Force, Navy, Army --- whatever you heart decides, after your service, the United States Armed Forces has what is called the GI Bill. It pays up to $150,000 for college education. I have some students in my class that i teach right now whom are reservists in the US Army national guard, and their college education are paid for through this GI Bill.
