The Flammenwerfer M.16. was a German man-portable backpack flamethrower that was used in World War I in trench warfare by the Germans. It was the first flamethrower ever used in combat, in 1916 at Verdun by the Germans. It was also used in 1918 in the battle of Argonne Forest in France against Allied forces by Germans, as featured in the 2001 film The Lost Battalion where the main character fights German, although an account in a 1917 issue of The Living Age suggests eyewitness accounts of it being used at the Battle of the Somme in 1916 by Germans.
