I been thinking that targeting drones would be nice to be able to make. But theirs on catch, how do you make your drones hostile to your own faction? This is what would be needed to make your unarmed targeting drones behave aggressively, and your turrets auto attack them. There needs to be a default generic "Targeting Drone" faction and a global option on faction blocks to set the faction block to this faction.
Alternatively
A "Set Hostile to All" option on the faction block would work for only one drone at a time. Otherwise the drones would be hostile to each other.
