Sorry but this "feature" has been around since OFP. Try setBehaviour "STEALTH". For OFP, sometimes(as for static MG at night) the only solution was a fast loop with the "LIGHTOFF" action. Waypoint behaviour/combatmodes will always over-ride other commands or actions. I would say you need your own FSM. You could trying asking CrashDome for some advice on using an FSM to do this.
