I've recently become more uneasy and somehat troubled by the moral dilemma of sinking merchant ships, much like the area bombing of civilians during the war by both sides, which I believe was a mistake and also wasted huge numbers of (especially) allied airmen, for limited results.
This got me thinking, why don't I try a new career and only sink Military targets?
The thrill of sinking a destroyer is anyway much more fulfilling for me than a merchant, as it's a kill or be killed situation.
Correct me if I'm wrong, but the renown for sinking some of the larger Battleships etc should be more than enough to progress in my career.
I guess the problems will begin to mount as the war continue's and the detection capabilities of the ASW units increases rapidly.
Personally I blame the realism of GWX3.0, which along with the fantastic radio pack by Olsen (i think), along with the lifeboat/ debris mod has increased my immersion no end.
I seem to remember that some U-boat commanders did this at the start of the war, but the practice soon stopped (again correct me if I'm wrong).
Somehow I don't think BDU will approve...
