The Wechselapparat M1917 was a lightweight flamethrower developed from the Kleinflammenwerfer M.16 ("Kleif"). It was, along with several other flamethrowers of the era, developed by Richard Fiedler, as early as 1901. Fiedler's designs were formative to flamethrower technology and analogous designs remained in use for many years.
An exchange apparatus (wechselapparat) was fitted between its central compressed air tank and the outer ring fuel tank, a weight-saving improvement over the heavier Kleif that operated from a single tank. It also uses the same ignition system as the Kleif ( a magnesium ignitor system).
The Flamethrower is featured in Battlefield 1. It is seen at several points during the Official reveal trailer.
The weapon is the primary armament of the Flame Trooper Elite Class. It can cast flames a fair distance ahead, some of which may linger on the ground and walls. There currently appears to be no limit to the flamethrower's fuel supply.
Damage is comparable to the Incendiary Grenade, with some damage inflicted after exposure.
