Since we are talking about triggers I have a question as well. Im trying to acomplish the same thing. trigger specific units only, but this relates to sp/mp support pack. when I call in fixed wing CAS or airstrikes, the aircraft hit a trigger which plays Aeons jet fly by sound.. which works great but i need only the jets to trigger the sound.. not the men on the ground.. since the jets are spawned from a marker instead of in the mission.. how do i acomplish this? thankyou
