Unreimbursed military moving expenses

[Opfor77]

This may be an easy answer, but here goes.  I know that military service members can deduct unreimbursed mileage related to a permanent change of station move.  If the taxpayer & spouse each have a car, can they both deduct the mileage, essentially doubling the mileage one way?  No places that I've looked talk about 2 cars.
