Your MBA is a soft factor that will be taken into account, contrary to what the admissions "experts" on this board say. If you don't end up where you want to first year, as long as your grades are good at the end of the first year, apply to transfer somewhere else. A former classmate and a friend of mine, former Army, did this very successfully.
It will be taken into account, but the question is how much? It probably pales as a soft factor compared to the actual military experience.
And it's dangerous to go somewhere based on the assumption that one will transfer; grades are unpredictable, and plenty of your classmates will be looking to get good grades and transfer as well.
OP: I can't tell you how admissions officers will consider your rather unusual situation, but I think your best course of action would be to thoroughly prepare for the LSAT and to explain your circumstances when you apply.
