They do exist I had them, captures the map only.

Other question regarding op fire filters play with them becomes obvious.
You can save 3 sets, if using WWII most obvious use is for armoured vehicles like tanks.

Example settings
Min armour 3 > wont fire on units with only 1 or 2 armour such as halftracks, light tanks
Infantry engagement range set to 5, its protecting itself really wont give fire support as will not fire at any infantry till its 5 hexes away.
Soft vehicles can do the same.
These all stop it getting distracted by not firing at lesser threats.
ATG range can set to something higher like 25 so it still fires at them.
AAFire on/off can be useful, sometime I set tanks to off leaving it to other units, stops giving away your location by firing at the plane.
