Actually, my advice about enlisting includes becoming an officer. The military will pay you to attend college, while in the military, for the purpose of becoming an officer. See this program:

You keep all military pay, plus $10,000 per year for college costs. That should work at Auburn, or any state university in Alabama (which I assume you reside). Notice that you are required to complete college in 36 months or less. In other words, attend summer sessions, or already have college credits. All of the military services have similar programs. Each is different though.
About a third of officers in the Marines started as enlisted. Probably about 20% did so in the Navy and Air Force. I think the Army is in between. I was not able to find exact statistics. I personally know several people who enlisted in the military and then became officers via programs such as STA-21. Very common.
I will admit, though, that this approach does come with risk. You might not get selected for STA-21. There is no guarantee. On the other hand, the military makes a strong effort to seek out people who would make good officers, and help them become one.
By the way, not only am an NROTC grad, I am also an Auburn grad. Warrrr… EAGLE!
