Wing Commander CIC

Im looking to build a cluster-bomb type missile that takes out turrets and nothing else. So far Ive managed the effect I want targetting fighters (looks VERY cool), and one missile splitting up and converging on a target that the previous missile was locked to. (also looks cool, but is far more pointless). Do missiles simply not "acquire new target" on childobjects or are they capable of doing so and I havent found the right combination of behavior tags yet?
