08/15 (1954)
08/15 is a 1954 West German film directed by Paul May and based on the novel 08/15 by Hans Hellmut Kirst who also served as the film's screenwriter. The term 08/15 (nill-eight/fifteen, ) 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. 08/15 is also the first part of the 08/15 film trilogy, hence it is also named Teil 1: In der Kaserne (Part 1: In the Barracks).
