15 Flammenwerfer weighed 75 lb full, while the Schilt No. Arditi used Schilt flamethrowers in combat only once. However, because the Arditi considered the Schilt too heavy and slow in operation, it was withdrawn from service with the assault battalions and replaced with the DLF (Apparato Italiano Modificato Tipo D.L.F.), and the Italian Twin-tank Apparatus (Apparato Tipo Italiano a Due Serbatoi Accoppiati), also called the Italian Intermittent-jet Apparatus with Automatic Ignition (Apparato Tipo Italiano a Getto Intermittente con Accensione Automatica). The I Reparto d'Assalto of the Second Army was the first Arditi unit to use flamethrowers in combat, during the capture of Mount San Gabriele, September 21, 1917. The Reparti d' Assalto were established on Jthe Bergomi Society of Milan had been supplying Schilt No. You can tell by the wide metal bands attaching the propellant bottle to the oil tank. The Arditi appear to have used these prior to the adoption and adaptation of French Schilt models. Italians using Austrian style flamethrowers (one of a series) The Americans purchased 48 Lawrence Knapsack Flame Projectors the one in that photo was being used by the Chemical Warfare Service to melt snow off of sidewalks in New York City in the fierce winter of 1920. Fries that Lawrence had "given a lot of trouble to the War Office, and they are not going to let him give any more, to themselves or anybody else." In February of 1918 Lawrence had told the Americans that his own design was superior to the Norris-Menchen flamethrower, adopted by the British in 1915. He then tried to demonstrate the weapon to the Americans in France but was prevented by the War Office. Lawrence went to Russia to demonstrate his flamethrower, which the Russians adopted in 1917. The example in this photo has a small, battery-operated hydrogen burner in place of the portfire you can see the hydrogen container on the top rear of the oil tank. Originally the Lawrence was fitted with a portfire beneath the nozzle, which the operator ignited with a friction fuse before he pressurized the oil. A hand grip resembling an old-fashioned car braking handle on the end of the firing lever allowed the operator to fire bursts with his left hand while he aimed the lance with his right. To use the weapon, the operator pulled down on the firing lever with his left hand, which pierced a small tank of carbon dioxide inside the oil tank, pressurizing the oil.

The rigid, swiveling lance was attached to the right side of the oil tank, while the firing lever was on the top you can see it behind the engineer's hat.
WARFARE 1917 FLAMETHROWE PORTABLE
The Lawrence had a range of 135 feet, much longer than that of other portable devices, and it weighed only 40 lb. That's a British Lawrence Knapsack Flame Projector Model 1917, a remarkable weapon designed by the equally remarkable Lieutenant Percy H.

And another shot of a different US flamethrowerīTW the French seem to have attached flamethrower men to the Americans on a semi permanent basis.
