@Blu3wolf:
How best should the gunner react to the defender repositioning?
Standard fighter pilot answer: it depends. And it really does. Enough to maintain the offensive. A lot of factors go into it: Vc, HCA, range. A slight lag off to create some LOS might be good enough. If it isn’t, you have co-roll and counter-roll repositions if the defender decides to tuck-under jink. If you really f*cked it up, then you need to quarter plane. However, expect to present reversal cues to the defender and him to try to reverse.
