Referencing pages 122-123, and page 140 of Total Warfare for this one.
Simple question first that I'm pretty sure I've already figured out the answer to myself but I'll ask just to be sure:
If an Armor Piercing AC round strikes a location that has only internal structure remaining but damage transfers in the same attack I assume the fact that the damage started on a location that was only internal structure the special critical is not applied in accordance with page 140 of Total Warfare. Is this correct?
