Disband, Withdraw, Reconstitute, Evaporate

[Marquo]

f a unit scheduled to withdraw is instead disbanded, what are the consequences? In case of withdrawal all the equipment leaves with the unit, but in case of disbanding, "Disbanded units are removed from the map and return their equipment
to your Supply Pool." Does this gamey loophole actually allow one to prematurely disband a unit to significant advantage?

If a unit is disbanded, but otherwise tagged to reconstitute, will it do so or is there a failsafe?

The manual uses the word "evaporate" only one time in reference to the fate of units sitting on a thawing super river/marsh; what does evaporate mean in regards to units KIA or during disengagement? All material and men lost? I presume so.
