Maybe there is some huge downside to manned ack in town or the strats/hq but JOACH1M has decided to throw a blanket statement instead of a proper answer........which means he will have to come back and qualify his answer later.
So.....the short and flippant answer does nothing for the thread and gives rise to posting inefficiency thereby lowering his value per post.
That said, how about some random manned ack across the arena......but without a dar station...or....better yet (but probably impossible) no ability to see any dar at all?
It would just be a gun in a remote location....alone ......with nothing but line of sight visibility and hearing engine sounds.
