My only advice would be to urge you to apply to MD in addition to DO. Unless you are dead set on the DO curriculum and practice, and hopefully you have a very realistic perspective based on experience of what that is like, the residency specialties as an MD are much more available. You have a stellar application from my perspective with stats just below most medians, but well within percentiles, making you a very competitive applicant. The only thing I don't see is research. Maybe do some research, either paid or volunteer during the interim between now and interview time...
Most other applicants aren't going to have the breadth of life experiences and ECs that you have, proving that question "would this person make a good doctor." The answer is an unequivocal yes based on your experiences. Guessing that like in most cases, the military has knocked the disillusioned pretentious-ness out of you, you might also make a great impression in an interview.
I'm not trying to talk you out of DO if you're set on that course, but if you're worried that you aren't competitive enough for an MD acceptance, I suggest you reconsider.
a note to add, I'm not knocking DO one bit, just stating the statistical truth that DOs are more limited in residency matching than MD students, which can be limiting to a DO physicians career.
Best of luck with the process!
