Gentelmen,
your sonar/radar men are not incapable, deaf or blind. It is an age old tradition of subsims for your sensor operators and bridge lookouts to be "slow" in their response so as to "reward" the players doing the actual job themselves. So no crew health problem!
They are double agents working for Ubisoft !!!!!! Traitors !!!!!
AAhhh
Kill them all !!!!!
Ok, I'm calm now! Thanks for the pill doc!
