From 1999 to 2000, the Russians employed flamethrowers against Chechen rebel forces during the battle for Grozny. Russian tacticians concluded that the flamethrower was effective as much for its psychological effect as its ability to flush insurgents or snipers out of enclosed or fortified positions. The Russian use of flamethrowers was also one reason why in 2003 the United Nations declared Grozny the most devastated city on the planet.
Interestingly, there are few restrictions on the design, construction and use of flamethrowers in civilian hands in the United States.
