What it is

A tank of flammable oil pressurised with compressed gas that projected a lit jet some 20 metres. Fiedler submitted models to the German army in 1901 and it adopted the weapon in 1911; it was used in combat in 1915 (Malancourt and Hooge).

Fiedler built the first models in 1901, demonstrated them in 1905 and teamed up with Reddemann in 1908; the German army accepted it in 1911.
