No AI seems capable of employing aircraft rockets accurately. I tested with Kajman and Xi'an. The shots are always long by at least a hundred meters, with the Kajman simply firing horizontally as it overflies the target. This is particularly problematic in that the aircraft will not engage heavy armor with their missiles until they have expended their rockets (which can take many runs). So they make a series of ineffective runs and then fire a Scalpel or two, killing the target vehicle. The transition from completely ineffective to completely lethal is very undesirable.
