I'm in a point in the Single-Player Campaign mission where I need to control a UAV and take out a target. I have successfully taken control of the UAV turrets, but when I press Mouse 1 (Fire), a red star appears on my screen, and clicking Mouse 1 again removes the star.
Can someone give me a detailed explanation on how to use the UAV in ArmA 3? Most importantly, how can I fire my UAV turret at an enemy?
(Please explain this as you would a child, as this is the first time I have ever played an ArmA game.)
