Anti-missile devices will shoot at ejecta that came from a wrecked enemy (and only an enemy) station. The annoying thing is if the device fires at a fast rate and has WMD, then what happens is some of those shots miss, hit the dead station, which causes more ejecta to fly away, and the device shoots more shots at them, and the vicious cycle continues for a while.

It would be nice if there was a way to prevent this, perhaps by excluding all ejecta in the first place.
