For all those resources, the chopper-killers are pretty much useless if they can't even detect choppers on radar. The more able players use the patrol circle attack method to circumvent triggering the AA defenses since their patrol circle is 50 and cruisers sight range is 40. What good are they for if they can't see choppers coming or even fire on them at all?
