Siegfried Knappe (15 January 1917 – 1 December 2008) was an officer in the German Army (Wehrmacht Heer) during World War II. Towards the end of the war, Knappe was stationed in Berlin, where he gave daily briefings at the Führerbunker.

As a young artillery lieutenant (Leutnant der Artillerie) in Panzer Group Kleist, Siegfried Knappe participated in the Invasion of France. Knappe was decorated for actions that took place on the night of 14 June 1940. The actions took place in the Paris area, south of Tremblay-en-France, at the Ourcq canal. A group of French sailors had apparently not been informed of the decision to declare Paris an open city. As a result, they were defending a bridge with machine guns from a house across the canal. After German infantry failed to clear the area with mortar fire, artillery support was requested. Though Knappe was the Battalion Adjutant and it was not his duty to man the gun, he moved up to the front with the infantry. Because the area was wooded, the 105 mm gun had to be brought up and fired almost at point blank range directly into the house. The German infantry was hidden behind a building by the bridge, where the gun was maneuvered, but in order to fire all seven crew members would be exposed to machine gun fire. On the mark, the gun was moved, aimed, and fired. Three of the seven crew members were wounded but the machine gun nest was destroyed. This action opened the road for the infantry.

Carlos Ray "Chuck" Norris (born March 10, 1940) is an American martial artist and actor. After serving in the United States Air Force, he began his rise to fame as a martial artist and has since founded his own school, Chun Kuk Do. As a result of his "tough guy" image, an Internet phenomenon began in 2005 known as Chuck Norris facts, ascribing various implausible or even impossible feats to Norris.

Norris appeared in a number of action films, such as Way of the Dragon in which he starred alongside Bruce Lee, and was The Cannon Group's leading star in the 1980s. He next played the starring role in the television series Walker, Texas Ranger from 1993 to 2001.

Norris is a devout Christian and politically conservative. He has written several books on Christianity and donated to a number of Republican candidates and causes. In 2007 and 2008, he campaigned for former Arkansas Governor Mike Huckabee, who was running for the Republican nomination for President in 2008. In the 2012 election he endorsed former Speaker of the House Newt Gingrich. Norris also writes a column for the conservative website WorldNetDaily.
