I have a similar problem with triggers;
To prevent Shilkas from firing at vehicles outside 1500m, i used a trigger with a 1500m trigger area, WEST-PRESENT.
In the activation field it sets the behaviour and combat mode to AWARE and OPEN FIRE. (Yes, i know there is a colorcode for COMBATMODE, but I can't remember them right now...)
In the deactivation field i set behaviour and combat to CARELESS and NEVER FIRE. (Yes, I know I it would probably be enough with CARELESS or NEVER FIRE... or?)
Everything works out fine if i DO NOT start with a WEST'ern unit inside the trigger, but if I start inside it, it seems the trigger won't activate...
Anyone else experienced that? Could it be due to many trigger on one mission - or something like that?

btw; I would like the shilka to ONLY respond to AIR (west) vehicles.. Any good solutions to that?
