A flamethrower is a handheld device that projects flames over a long distance. Similar to a blowtorch, it is commonly used by military personnel for warfare or by firefighters to control and extinguish large fires. There are several alternative terms for flamethrower, including fire hose, incendiary device, fire-breathing weapon, and flame projector. Furthermore, slang terms like dragon launcher or fire spitting gun are sometimes used to describe the flamethrower. Despite its destructive nature, the invention of the flamethrower revolutionized warfare as it allowed military troops to attack enemies hiding in trenches or bunkers.
