The academic issue is low, but one thing to realize is they will look at your school profile when they review that issue. If the school profile is academically competitive, the gpa still matters, but will be viewed differently.
The way they look at the profile is the % of students that go Ivy, 4 YR Private/Public, 2 yr, Tech and no further education.
So if you are ranked top 15%, but 25% go to Ivy, 50% go 4 yr, and 25% go 2 yr. you look better than if your school send 1% IVY, 40% 4 yr, 34% 2 yr and 25% no further, it will hurt you.
They will also look at the school curriculum, so if you took 2 APs and they offer 16 it is going to be viewed differently from a gpa standpoint compared to the candidate that took 9 and 16 were offered.
Every kid will say they attend a competitive school, but what the student thinks is competitive and what they think can be 2 different perspectives. This is why they request a school profile with the transcript. They also look at the pt scale and weight. Some schools have a 10 pt scale and some have a 7 pt scale. Some give an A as an A , some will give a gpa using the actual % in the class, I.E. 95% X 4 = 3.8, uwgpa, whereas, another school will give 4.0 regardless of the %. That is why I am saying the gpa appears low, but actually could be re-scored by them to their standard. It is not uncommon to see gpas go up, go down or stay the same.
Additionally, I would look into if NROTC does composite. I know AFA does composite, but AFROTC takes the best sitting, there is no superscoring.
Finally, your intended major will be a part of the equation. 85% are awarded to tech majors. If you intend to go non-tech, beware stats are typically higher since there are fewer scholarships offered.
You have 0% chance if you don't apply. Nobody sits on any board and what was competitive ly may not be this yr. What may have not received one LY, may receive one this yr. Nobody knows, manpower needs, budget and economy will matter regarding how it will sort out.
