The following problem is explained when the UAV ist used only by one member of the team, for example the uav operator alone.
The Unmaned Aerial Vehicles have some worng values in flight speed and flight height when being not controlled by a uav operator or when he just controlls the turrent of it. They are false neither when the uav has waypoints nor flying without waypoints. Then the UAV is flying way to low and way to fast. When the operator then wants to laser a target, the uav is engaging it, what is right, but because of the low altitude and the fast speed its nearly impossible to target the enemy and get a good shot on him. Most of the time the shot misses or the missle isnt fired at all. So the only way to use the uav properly, is to give it a waypoint like search and destroy and hope, that it destroys all targets and isnt being destroyed in the process (yes, uavs are still a bit buggy).
