How to set a trigger if a unit has detected a unit from a different coalition?

[TEMPEST.114]

I did search and couldn’t find an answer 

I’m trying to create a mission where some apaches are trying to find a specific ground vehicle. If any of the other red coalition ground vehicles visually see those Apaches I want that to trigger a quick response of a late activation enemy red Helo attack.

I can’t find any way to set a trigger based upon if a unit has (visually or radar) detected another unit from a different coalition - where am I going wrong?

@Elphaba you can do that with a short script. Example attached (when any red group detects the Apache, it triggers a M.E. trigger by flag that activates Migs and a message - 3rd BTR group does detect Apache. There is no exclusion of any red ground group, for Apache detection, but it can be added)

The little script will work as is in any mission for all Red ground groups as detectors, and only unit with Pilot's name/unit name : Apache as target to detect.

Thank you so much!
