How can a military spouse make an argument for custody?

Let’s say that the woman is the military spouse who is in the Air Force, and the husband is the civilian. She wants custody, but he thinks that her schedule would make it difficult. He contends that the possibility of an overseas assignment argues against her receiving custody.

At one time there was a sort of unspoken presumption against service members obtaining custody. This is apparently no longer the case, for the most part. On the other hand, if a spouse is in a unit that is frequently sent overseas, or if she is in a unit that has an irregular training schedule, then the fact of her active duty would probably work against her obtaining custody.
