Is there something you could do that suits your interests? Work at/open a firing range? Also, I know that school might not interest you too much but it will most likely provide you with some extra knowledge that will open doors for you. You could suck it up and study something and have a day job, and dedicate your free time to your hobbies that make you happy. Also, how can being a friggin MARINE not be enough! It's seems to me that you'd be overqualified if anything. What other requirements are they asking for?
