Flag of Nazi Germany
The flag of the Nazi Germany was a patriotic banner that symbolized that region of Earth during the mid-20th century. 

It consisted of a red field with a black swastika set inside a white circle. In the Hirogen holodeck recreation of WWII, the holographic Kaptain spoke of the Nazi flag, and how it described their destiny: "The field of red, the purity of German blood. The blazing white circle of the sun that sanctified that blood." () 

In an alternate timeline, Adolf Hitler's forces marched onto the North American continent; newsreel footage from that situation depicted the 1944-spec United States flag being flown under one of Hitler's Nazi flags. ()
