What about the whole Pieper issue? People have seemingly given reasons for him his command being incredibly unlikely, both in his association with different massacres and his limited tactical experience.
There's also the fact of him having originally been sentenced to death from the Malmedy massacre trial before it going to a twelve year sentence.
And y'know, there's also another thing I was thinking about. In wondering explicitly why, you have Hans-Ulrich Rudel involved. This is a figure who helped to bring Nazis into Latin America (which included Josef Mengele, the noted war criminal and person in charge of human experimentation in Auschwitz) along with having received the highest award available in Nazi Germany, only able to be awarded by Hitler himself. It raises some very interesting questions as to why specifically you have two Nazi war criminals, Joachim Peiper and Hans-Ulrich Rudel being involved here. You have two specific Nazi war criminals being involved here who apparently 'renounced' their history when they did anything but, having consistently defended it (Peiper calling the Nuremberg trials as propaganda and Rudel remaining involved as the leader of numerous Neo-Nazi parties and having helped Mengele escape into Latin America) throughout their history. Would be really interesting to know as to why The Congressman decided on those two specific Nazis to have in charge.
