OK. For reference on the Torpedoes, we used
Torpedoes of the United States of America on the NavWeps site, but made things a bit earlier, and differences between the various boats. As for the Special Ability, if I remember correctly, it is only one per character, but that Special Ability does not always match their specialty, such as what you've seen with the officer of the watch getting the Perfect Pitch. I have had a torpedo man get the medic ability, and swapped him to the Damage Team, so I could move him throughout the boat easier, and not lose a torpedo man when he might be needed, replacing him, of course, prior to the next patrol. An officer is not easy to replace in SH4 though...
