So I was running through the training missions the other night, again, got to the convoy mission, and had a modern tanker dead in the water being protected by 2 destroyers and I only like 4 torps left. To this point I had no confirmed sinkings. I needed 10,000 tons to complete the exercise. I wasn't sure if that tanker would meet the goal so I went to the ingame ship id book, and found that it only contained warships. Was I doing something wrong??

I did wind up sinking that tanker and it did complete the mission for me though.
Thanks!
