Then the issue is seemingly with having a large military that stays well-trained at all. There isn't any way to do that without expending enormous amounts of energy. Keeping a flight rating, along with all the unit-level qualifications necessary of ground armored combat forces burns far more fuel than commuting, even commuting by plane. I would even say it's conceivable that having permanent housing in the middle of the desert might be worse than flying them in from elsewhere, but considering they're flying in from Vegas, living there probably isn't much better.
