I know this has been asked before, but as it turns out, I'm apparently a complete imbicile with the search function, and can't find anything.
I would like to know how to make a trigger activate by any Bluefor unit, except if the unit is a aircraft.
So if a bluefor man walks into the trigger, it will activate, but if the same man flies into the trigger, it will not activate.
Setcaptive is not an option.
