I looked in the wiki community manual, it has weak spots for most ships but not a T3 Tanker. I have one fish left, I want the one shot/one kill if I can get it. The manual says for a T2 to set depth on torp to 3 meters and aim for the gas aft of the smoke stack. Does this apply for the T3 or am I hosed? Naturally, it's stormy weather.
If I can't get it, no big loss, I have over 60,000 tons sunk on this patrol alone and I go home to a Knights Cross with Oak Leaves and Diamonds either way. I just want to get efficient with these torpedoes. I'm going to need to when attacking convoys and Destroyers ready to be heros themselves.
