Disapperaing Helicopters

You should get a warning at the start of the scenario in a dialog box "This Scenario Has Withdrawals". Achtung baby.

Can't remember if you get that every turn. (Maybe that is a feature to add - or at least a flash on the turn they are due.)

You can also check in the reinforcement/withdrawal dialog. (And there you can see if the withdrawal is random.) I used random withdrawals in the House to House expansion to reflect the uncertainty of assets at your disposal. Gunships were in demand all over the place and if you don't use them, you might lose them.

For the big air transports, I think that was a way of preventing them from being used ahistorically - dropping troops off, then hiding and popping up as a scout, etc.
