Really. My grandfather was a German officer in WWI and Jewish. His father was an officer in the Prussian (? Can’t recall) military.
Hitler’s own LT in his unit was German.
I don’t think it was uncommon, at all.
“Hitler’s own LT in his unit was German.”
I know what you meant..,jewish. My recollection from readings is that he was a good man/officer and Hitler respected and protected him going forward.
