I have had occasions where the cargo was more important than the ships and have let four-of-four AKs go down at the destination port in order to get every precious supply point off
Going to have to rethink that strategy once the damage cargo stuff goes public ... ships loose goodies now when they get hurt. the suicide run where they get to unload everything then sink will not be as profitable any longer [;)]
Time to get them CV's off their butts and actually use them to escort convoys instead of racing around the ocean playing tag with each other [:D]
