Help with a simple AI mission

Im trying to make an AI Su-27 shoot down a AI Huey helicopter. I got two problems.

The jet wont shoot the helicopter, I tried PerformTaskEnroute>SearchandDestroyInZonebut it just passes it by, it also doesn't work when I PerformTaskEnroute>SearchandDestroyUnit. It just passes it by and goes to airport and lands, wtf.

Is there a simple way to do this?

That was a bit odd, I expected Search Then Engage ... to work out of the box -- it didn't this time. However, setting ROE to WEAPON FREE finally did the trick and units get engaged.

Interesting what you did.

Someone mentioned to me that the jet isn't finding the helicopter, so add more way points so it keeps searching.

I ended up trying something else, I stuck to one waypoint; SearchEngageUnit, but I copied that jet so there is 5 of them. That worked; helicopter was downed, so good enough for me.
