In one scene, Colonel Hogan introduces himself as an officer in the US Air Force. Well, the US Air Force wasn't created until 1947, three years after the War ended and at least that long after the scene portrayed in that episode took place.
In another scene, a Nazi officer pulls down a wall map of Europe. The map illustrates East and West Germany which were allied and Soviet Union occupation zones established in 1945 AFTER the War ended.
I've never seen HOGAN'S HEROES but chalk this up to bloopers. Someone didn't do their homework for these episodes.
