Le traître

One of the first films after World War II to portray the German people--outside of the Nazi regime--in a sympathetic light.

Karl is mistakenly called a corporal. The Luftwaffe uniform that he wears both in the US POW cage and while back in Germany has the rank insignia of an "Obergefreiter", specifically three winged emblems on the collar patches, plain shoulder straps and two chevrons on his left sleeve. Also when the list is checked for his name at the bridge the rank is written down as 'Gfr' (gefreiter) The ranks of Gefreiter, Obergefreiter and Stabsgefreiter (all which were partially identified by chevrons on the sleeve) were not NCOs and had no command authority over other soldiers. They were simply grades of seniority and would be more equivalent to Private First Class (PFC) in the US military. The German rank that is the closest equivalent to Corporal is Unteroffizer. Also, Karl is wearing the medical badge on his right sleeve; Luftwaffe enlisted medical personnel wore the badge on the left sleeve, while Wehrmacht (army) wore it on the right.
