So I'm a total noob, and I'm just trying to make a few random missions in the editor where I'll be the gunner of an MQ-9 Reaper and shoot Hellfire missiles at targets. But the laser designator doesnt seem to do anything, and when I fire the missiles, they go off in all different directions and never seem to track the laser. So how do I set up/use the Reaper drone and the missiles on board?
