Yup. What CD means is that you start off these loons with
this setBehaviour "safe"
in their init field. Then you have a trigger somewhere with his line of code in it. The conseqences of the trigger will happen when the loon in question goes from safe to aware or combat. It is likely, depending on exactly what you are trying to do, that setCaptive true/false will come into it somewhere.
If you are playing about with civvies you will probably need to use the group-leader-is-east/west-with-deleteVehicle-this-in-his-init-field trick to make the civvies on a particular side.
