Hi, yesterday I encounterd a merchant and fired my last torpedo at her. It was a hit, but she didn't sink. So I surfaced and orderd my deck gun crew to open fire upon the merchant. It did take a long time...too long for me and I decided to help by shooting with the AA gun. The merchant was shooting at us as well.
All of a sudden explosions occurd everywhere I shoot and she started sinking.
So my thoughts are:
1) When i order my deck gun crew to shoot at her water line, can I shoot at the Merchant gunners with the AA gun. Can you actually kill enemy sailors (specially their gunners?)
Usually I never use my AA guns, when a plane contact is made, I dive and I dive deep. So it would be kinda nice to use the AA gun at merchants.
