Your GMAT is very strong, and the fact that you're coming from the military makes you a very appealing candidate overall. Admissions officers won't have many questions about your ability to lead, so you're starting with a head start vs. most other applicants there.
I do wish you had a little more extracurricular experience, but I don't think this will be a deal breaker. Just be sure to overcome one weakness that some military applicants face -- being able to demonstrate that they "get" the business world and are realistic about how an MBA can help them transition into a new career field. You already are unique by virtue of your military experience. Now you just need to show how you'll successfully fit in with your "more traditional" business school classmates.
Good luck!
