Hello I have just started playing arma 2. I have been told that I have command of a transport helo. I have figured out how to get my squad to enter and leave, and I have figured out how to get the chopper to go somewhere on the map to pick us up. What I can't seem to figure out is how to make the chopper take my men somewhere on the map. I have done the training, maybe I missed something. How do I do this? Thanks
