Hey,
I saw the movie ;D. It's really good. I don't know about the wounded, but I did a mission where my squad entred a chopper and diembarked in the middle of the battle. The chopper flew back to base and took one more squad to the battlefield. After the battle was over the heli. came back and took first our squad back to the base and then the other one.
In total there were 3 choppers and 6 squads. It was fun ;D
.
Ok, say you have a squad on the ground. You give them a waypoint get in, and then a second waypoint there where you want them to attack ( for example ) in the battllefield.
Now you put a blackhwk ( flying ) and a waypoint load ( i think
) and synchronize it with the get in waypoint. Next you give the waypoint for the chopper unload there where you want them to disembark.
Now to retreat them you do the same thing.
Hope I helped with my limited knowledge of editing
cheers
