Flamethrowers, as offensive weapons, projected streams or bursts of fire.
A weapon system with a history spanning millennia and a infantry staple, flamethrowers saw modernization at the hands of Mandalorian super commandos and Republic era clone troopers throughout the duration of the Clone Wars. While often deployed as an anti-personnel weapon—exemplified by the wrist-mounted flamethrower utilized by bounty hunter Jango Fett—some individuals, such as the Dug podracer pilot Sebulba, incorporated flamethrowers onto their vehicles. Sebulba employed his flamethrower against rival podracers as a means to cheat his way to victory in the Boonta Eve Classic.
Mandalorian warriors frequently integrated flamethrowers within their vambraces, considering them one of many tools designed to counter Jedi threats. The reasoning for this was that flames could not be stopped by a lightsaber's single blade, forcing the target to evade. A Force wielder possessing sufficient skill, strength in the Force, and reaction time could potentially shield themselves from the flames using the Force, but this demanded significant exertion. Mandalorian plasma shields were also a viable defense against flamethrower attacks.
During the Boonta Eve Classic, Sebulba outfitted his podracer with flamethrowers. He used them as a weapon against other podracers in order to secure victory in the podrace. Bounty hunters, including Jango Fett and Cad Bane, deployed flamethrowers against Jedi.
During the Clone Wars period, clone flametroopers serving under Jedi General Ki-Adi-Mundi and Clone Commander Jet utilized flamethrowers against the native Geonosians during the Second battle of Geonosis. Mandalorians, including members of Death Watch, the Mandalorian Guards, and Mandalorian super commandos, employed flamethrowers against their adversaries. Gar Saxon of the super commandos had a ZX flame projector integrated into his arm.
Elite Squad Troopers within the Galactic Empire were sometimes armed with flamethrowers. During the Galactic Civil War, both Imperial flametroopers and Rebel Alliance flame troopers made use of them. Imperial dewback troopers utilized CR-24 Flame Rifles throughout the reign of the Galactic Empire.
Gideon's Imperial remnant possessed at least one incinerator trooper.
During the Cold War era and the subsequent conflict against the Resistance, the First Order made use of flametroopers.
