Hi roofs, :welcome to Armaholic
Well, its a feature added to the evolution mission. I assume all you have to do is get in a chopper, hover above a vehicle and use the command menu to lift the truck.
I guess its done with scripting since you say you do not have an addon for it and if it would have been an addon you would not have been able to join the mission.
Since you played the mission you have downloaded it to your computer. You can read in our FAQ
how to find the mission yourself so you can open it and view how the script works (if you want to know that).
**Topic moved to missions and renamed.
