Hi, I'm trying to get a blackhawk to carry a HMMWV and a few troops to drive it, and drop it off somewhere, and have the troops get in/use the HMMWV. I know how to get the troops to get out, but I have no idea how to make a helicopter carry a vehicle (or possibly even a cannon) underneath it, or have it drop it off at a specified waypoint. Please help? :D
