More crew on Deck (when gunners are sent to deck gun)
 

It's become much too obvious now, there is more crew members need it on the deck when the crew is sent to man the deck gun. I've seen the wallpaper and may times in videos and documentaries there are more than 2 crew members on deck operating the deck gun. I would estimate about 6 or 7 in total. Either way someone get more men on that deck gun, who's loading it? who's helping with it's rotation and so on
