Questions Regarding Scenario Development

[Imp]

As Suhiir said this works, only downside is the uncrewed gun vehicle can only be destroyed by entering the hex till it is manned.

With helicopters it can be done did one with Chinese advisors trying to escape by helo.
From memory you need to adjust the helos Load Cost to something smaller so it can fit in the plane.
Important save before unloading, once the crew splits from its vehicle you cannot move that vehicle, also remember you will be deleting the planes so buy them with that in mind.
