Best way to get helicopters to attack with rockets.

[Gunfreak]

I want a couple of gazelles to empty their rock pods on some ground targets (static objects) and they refuse to comply. Since they are statics I can't use CAS.

So I have them on ground attack. I've tried attack map object and I've tired bombing. The helicopter refuse. They start their attack run. Then break off and fly to the next waypoint.

I've put them to ignore attacks(not that they are attacked anyway)

Will carpet bombing work?
