Who Am I ?
Hope It's not an easy going

Looks a lot like Léon Degrelle, but in Wehrmacht uniform that hardly seems possible.
LOL, I have been meaning to search, but pictures require a lot of work (for me anyway) and I have spent the weekend being distracted by "questions".

hmm ok an hint, I know it's hard to klick through all Knight Cross with Oak Leaves holders of the Wehrmacht

,
he was a part of an tragical chapter in this war
and he fought in ww1 and ww2
tragic for whom? Germany or Allies?
tragic for his troops and finally for him
Otto Wöhler. Does not look like the right man, but he did win the Knight's Cross.
is not this guy never saw his 90th birthday
