Set flag on embarking?

[Mangrove Jack]

I am trying to set flag on embarking a unit but cannot get it to work. I have Infantry M4 in Zone and AI Huey flies in and embarks solider. I have been basing flag attempt, on solider.

 

I have tried unit out of zone; coalition out of zone; part of coalition out of zone; All of group out of zone and Unit dead. None lead to flag set so I assume something is being done behind scenes - maybe they are being set invisible?

 

Anyone know how to set a flag after embarking a unit or do I just have to assume that solider is on board and base flag off the Huey?
