I'm not too clear on the use of a target designator for something like a missile or mortar.
As I read it, it seems to say that if you're using a target designator, you have to make a ranged attack with the designator, using something like the Pistols skill.
My character uses a mortar mounted on a drone such that it fires and reloads automatically when I use the target designator. Basically, I highlight the target with the designator, signal the drone, it fires on the mark.
What skill would that work with?
Our GM has ruled that it's a Pistols skill roll with the designator.
