08/15 is a 1954–55 West German film trilogy directed by Paul May and based on the novel "08/15" by Hans Hellmut Kirst who also served as the film's screenwriter (published in English as "The Revolt of Gunner Asch").
 The term "08/15" (nill-eight/fifteen, German: "Null-Acht/Fünfzehn" ) refers to the German Army's standard machine gun, the 08/15 (or MG 08 model 15), by far, the most common German machine gun deployed in World War I.
 It was manufactured in such large quantities that it became the German Army slang for anything that was standard issue.
A mitrailleuse (] ; from French "mitraille", "grapeshot") is a type of volley gun with multiple barrels of rifle calibre that can fire either multiple rounds at once or several rounds in rapid succession.
 The earliest true mitrailleuse was invented in 1851 by Belgian Army Captain Fafschamps, 10 years before the advent of the Gatling gun.
 It was followed by the Belgian Montigny mitrailleuse in 1863.
 Then the French 25 barrel ""Canon à Balles"", better known as the Reffye "mitrailleuse", was adopted in great secrecy in 1866.
 It became the first rapid-firing weapon deployed as standard equipment by any army in a major conflict when it was used during the Franco-Prussian War of 1870–71.
 A steel block containing twenty-five 13 mm (.51 calibre) centre-fire cartridges was locked against the breech before firing.
 With the rotation of a crank, the 25 rounds were discharged in rapid succession.
 The sustainable firing rate of the Reffye mitrailleuse was 100 rounds per minute.
 The maximum effective range of the Reffye "mitrailleuse" was about 2000 yards; a distance which placed their batteries beyond the reach of Prussian Dreyse needle rifle fire.
 Reffye mitrailleuses were deployed in six gun batteries and were manned by artillery personnel.
 They were not infantry support weapons but rather a form of special artillery.
Captain Willy Schultz is a fictional comic-book soldier, a German-American U.S. Army captain during World War II, who after being falsely accused and convicted of murder, escapes and blends into the German Army while seeking a way to clear his name and retain his Allied allegiance.
 Created by writer Will Franz and artist Sam Glanzman, the character starred in the feature "The Lonely War of Willy Schultz", which debuted in Charlton Comics' "Fightin' Army" #76 (cover-dated Oct. 1967).
The Pianist is a memoir by the Polish-Jewish pianist and composer Władysław Szpilman in which he describes his life in Warsaw in occupied Poland during World War II.
 After being forced with his family to live in the Warsaw ghetto, Szpilman manages to avoid deportation to the Treblinka extermination camp, and from his hiding places around the city witnesses the Warsaw ghetto uprising in 1943 and the Warsaw uprising (the rebellion by the Polish resistance) the following year.
 He survives in the ruined city with the help of friends and strangers, including Wilm Hosenfeld, a German army captain who admires his piano playing.
