Hey, Try this:
Soldier: Place a soldier (Named Spotter)
Place a trigger and set it up to be triggered by BULFOR
Trigger: In the (On Act) box put this in
Spotter fire ["GP25Muzzle","GP25Muzzle","FlareWhite_GP25"];
You could also use other colours:
"FlareGreen_GP25"
"FlareRed_GP25"
"FlareYellow_GP25"
When the trigger is triggered, The soldier will fire a flare in to the air.
Not sure how to make the soldier fire ar a specific target yet though.
Anyone got any ideas?
