I read that John Banner was born in Austria but moved to America when Hitler rose to power.
Mr. Banner joined the American Armed Forces and was a Supply Sergeant before becoming an actor. It said his last appearance was on an episode of “The Partridge Family”
I guess that’s an E-6 designation above an E-5 Sergeant? (one result shows it as E-6)
Been too long since I worked for the Marine Corps - IIRC E-6 was Staff Sergeant, E-5 Sergeant, E-7 Gunnery Sergeant
Leon Askin, who played General Burkhalter, fled Austria to the United States in 1940, after having been beaten and abused by the Nazi SA and SS. His parents were murdered in the Treblinka death camp. He then served in World War II as a Staff Sergeant in the U.S. Army Air Forces.
He lived to the age of 97.
