Bingo! (It's KURsk, by the way.) As an ex-sub sailor myself, I can verify that sentiment. Funny how you can spend a career training and drilling to take out as many Soviet boats as possible, as quickly as possible, in the event of war. Yet, I think just about anyone in the Brotherhood of the 'Phin would risk themselves in a rescue attempt on an opposing sub, if they were close enough to help, and it was peacetime.
