Flammenwerfer M.16.

The Flammenwerfer M.16. was a German man-portable backpack flamethrower that was used in World War I in trench warfare. It was the first flamethrower to be used in combat ever, in 1915 at Verdun (Not to be confused with Verdun 1916). It was also used in 1918 in the battle of Argonne Forest in France against Allied forces, as featured in The Lost Battalion (2001 film), although an account in a 1917 issue of The Living Age suggests eye witness accounts of it being used at the Battle of the Somme in 1916.
