General von Kleber was Generaloberst Dohrmann's chief of staff. He was an old friend of Hauptmann von Hecht's father. During the interservice rivalry between the SS and the Wehrmacht, he sided with his friend's son against Standartenführer Jannings. In retaliation, Jannings was able to somehow get von Kleber "relieved of his duties" in Italy. What became of him is unknown.
