I'm not sure I understand. You want a civvy to shoot a civvy, right?
OK. In the Intel box set Resitance friendly to West (say). Create an East officer. Group the victim to him, so that the officer is the group leader. Make the probability of presence of the officer zero. In the init field of the victime write
this setCaptive true
Name the victim victim1.
Now give the shooter a weapon. When you want the shooter to shoot the victim have this code in a trigger, wayopint, whatever
victim1 setCaptive false
The shooter will think that the victim is an East soldier. Since the Resistance is friendly to West (and therefore enemy to East) the shooter should shoot the victim.
