I updated the trig2 (see above) for better event in mountainous site

and for moving bad guys on site crash, it's better to add a 3rd trigger: trig3
condition: triggerActivated trig2 with a countdown set to 3 sec for example,
then on act:
opfor_group setCombatMode "red"; wpt_red = opfor_group addWaypoint [getPosATL helo,30]; wpt_red setWaypointType "SAD"; wpt_red setWaypointSpeed "full";
