Even knowing it is coming, it still takes days to work through and is held on a normal drill date. If it was for real (real deployment somewhere) it would still take days. An exception to this is Reserve aviation units, as the bulk of the maintainers are already on AD and there are always plenty of Reserve bums around to get crews together and pay them via other types of pay before they can get orders cut. While the time it takes may seem excessive, Reserve personnel need to be on orders legally. Current active units are already covered in that regard but a 'drop everything go to X tomorrow' us a non-starter as well. At best, you'd get an advance party in place within 24 hours with the main unit to follow. That's what XOs and assistant 'S' officers are for.
