I admire your commitment to historical accuracy, and it's great that modders like yourself are around.
A little off point, but when I played SH3 at 100 percent realism, I found it challenging but less entertaining than playing at around 70 percent realism. Therefore, for me anyway, I'm happy to discard some level of realism in order to enjoy the game more. I accept that others would have a very different view and I respect that.
