hi,
i would set the RACs friendly to the east. That will influence the civilians too. They will see west units as enemy then. To make it look not to obviously, i would set all civilians into unit-position "up" and give them lower combatmode and behaviour with:
civ1 setUnitPos "up"
civ1 setCombatMode "blue"
civ1 setBehaviour "careless"
etc.
After your initial action (the chopper extraction) happened, you can give them weapons wiith the addWeapon-command, turn the unit-position back to "auto", give higher combatmode and behaviour:
civ1 setUnitPos "auto"
civ1 setCombatMode "yellow"
civ1 setBehaviour "aware"
etc.
Or maybe you have an defined array with all civilians like:
all_civs=[c1,c2,c3,c4,c5,c6,c7,c8,c9,c10,c11,c12,c13,c14]
then you can set them back with:
{_x setUnitPos "auto"; _x setCombatMode "red"; _x setBehaviour "aware"} foreach all_civs
