@Emission: I usually put a waypoint to them and then I change TYPE to GET OUT, not UNLOAD. I guess UNLOAD is only unload transport, and not get out the whole squad.
But I left a little cheat in the mission: if you don't want to load and unload them, you can use 0-0-2 radio conde intread of 0-0-1. It teleport all squad to the starting positions (the last safe place before battle).

I couldn't succesfully manage to get the whole squad out of the trucks. I was using unload option on waypoint, which leaves the team leader in as the driver. Is there another way to unload?

I love high commander missions. it's like chess.
good work. thank you for this mission.
DANGER! Spoiler!
