==Moving Ships and Planes==
You can literally move a TAC from Stalingrad to Paris in a few hours, but the supply system doesn't notice that this happened until the wing shows up at the destination. This means that ships and wings have a "spin-up" time if no ships or wings were based in the destination province. For instance you might occupy France and
rebased 30 u-boats to French ports, only to wait a week before the fuel and supplies catch up to them at their new naval bases.
