Another "nasty" little surprise to a player is that the gun and deck watch positions are not "protected" from depth charges. The way the game handles the positions on the deck is slightly weird, in that they are always out there, just that they turn "invisible" underwater. So if you are about to be depth charged, move your active watch crew and (especially) the gun crews to empty berths somewhere, if at all possible. That will place them "inside" the submarine, protected by its "armor" - not that they can't still be injured, just that they have a little more "armor protection". The deck watch has the conning tower "armor" to hide behind if left in position, but the gun crews don't - go figure...
