I have played with side, unit type and behaviour.
Works perfectly. Resistance side zone works as well.

Does not work at all.
Removing waypoint config did not change a thing.
Does not work. It only removes zone, waypoints etc, but units stay where they were.
I think there is a problem in DAC_Delete_Unit.sqf, but... :)
//EDIT
Can I set resistance to be friendly to everyone ?
I only see three options.
