How do you decide between the assignment you don't want and the assignment you REALLY don't want? I mean, when there are a total of, say, seven possible assignments. And you don't really want any of them, because there are other assignments ranked "above" them, but NO ONE is getting those.
So how do you choose? How much input do you (the spouse) have? Do you base it on his happiness or your probability of getting a decent job?
Honestly, for all the difference it will probably make (since it is, technically, needs of the Air Force that decide it) we might as well rank it by the restaurants each possible station has. At least then I could have some decent food.
