If i'm chasing a single contact in heavy fog and find out it's a tug or trawler, then it's going to pay (my flak crews love me for it!)
I love sinking them, especialy when it's going to be hard for the aircraft and ships to respond. Remember it's war, depriving them of fish may not be as fun as oil, but if they get hungery, I'll gladly send a tin fish their way!
