. They can be vehicle-mounted, as on a tank, or man-portable. The man-portable flamethrower consists of two elements—the backpack and the gun. The backpack element usually consists of two or three cylinders. In a two-cylinder system, one cylinder holds compressed, inert propellant gas (usually nitrogen), and the other holds flammable liquid, typically some form of petrochemical. A three-cylinder system often has two outer cylinders of flammable liquid and a central cylinder of propellant gas to maintain the balance of the soldier carrying it. The gas propels the liquid fuel out of the cylinder through a flexible pipe and then into the gun element of the flamethrower system. The gun consists of a small reservoir, a spring-loaded valve, and an ignition system; depressing a trigger opens the valve, allowing pressurized flammable liquid to flow and pass over the

and out of the gun nozzle. The igniter can be one of several ignition systems: A simple type is an electrically-heated wire coil; another used a small pilot flame, fueled with pressurized gas from the system. Flamethrowers were primarily used against battlefield fortifications,

, and other protected emplacements. A flamethrower projects a stream of flammable liquid, rather than flame, which allows bouncing the stream off walls and ceilings to project the fire into unseen spaces, such as inside bunkers or pillboxes. Typically, popular visual media depict the flamethrower as short-ranged and only effective for a few metres (due to the common use of propane gas as the fuel in flamethrowers in movies, for the safety of the actors). Contemporary flamethrowers can incinerate a target some from the operator; moreover, an unignited stream of flammable liquid can be fired and afterwards ignited, possibly by a lamp or other flame inside the bunker. Flamethrowers pose many risks to the operator. The first disadvantage is the weapon's weight and length, which impairs the soldier's mobility. The weapon is limited to only a few seconds of burn time, since it uses fuel very quickly, requiring the operator to be precise and conservative. Flamethrowers using a fougasse-style explosive propellant system also have a limited number of shots. The weapon is very visible on the battlefield, which causes operators to become immediately singled out as prominent targets, especially for snipers and designated marksmen. Flamethrower operators are rarely taken prisoner, especially when their target survived an attack by the weapon; captured flamethrower users were in some cases summarily executed. The flamethrower's effective range is short in comparison with that of other battlefield weapons of similar size. To be effective, flamethrower soldiers must approach their target, risking exposure to enemy fire. Vehicular flamethrowers also have this problem; they may have considerably greater range than a man-portable flamethrower, but their range is still short compared with that of other infantry weapons. The risk of a flamethrower operator being caught in the explosion of their weapon due to enemy hits on the tanks is exaggerated in films. In some cases, the pressure tanks have exploded and killed the operator when hit by bullets or grenade shrapnel. In the documentary ''

bursts outward when punctured. The fuel mixture in the containers is difficult to light, which is why magnesium-filled igniters are required when the weapon is fired. When pierced by a bullet, a metal can filled with diesel or napalm will merely leak unless the round is an incendiary type that may ignite the mixture inside. The best way to minimize the disadvantages of flame weapons was to mount them on armoured vehicles. The Commonwealth and the United States were the most prolific users of vehicle-mounted flame weapons; the British and Canadians fielded "Wasps" ( Universal Carriers fitted with flamethrowers) at infantry battalion level, beginning in mid-1944, and eventually incorporating them into infantry battalions. Early tank-mounted flamethrower vehicles included the "Badger" (a converted

Operation

A propane-operated flamethrower is a straightforward device. The gas is expelled through the gun assembly by its own pressure and is ignited at the exit of the barrel through piezo ignition. Liquid-operated flamethrowers use a smaller tank with a pressurized gas to expel the flammable liquid fuel. The propellant gas is fed to two tubes. The first opens in the fuel tanks, providing the pressure necessary for expelling the liquid. The other tube leads to an ignition chamber behind the exit of the gun assembly, where it is mixed with air and ignited through piezo ignition. This pre-ignition line is the source of the flame seen in front of the gun assembly in movies and documentaries. As the fuel passes through the flame, it is ignited and propelled towards the target.


History

. Later, during the Byzantine era, sailors used rudimentary hand-pumped flamethrowers on board their naval ships. Greek fire, extensively used by the Byzantine Empire, is said to have been invented by Kallinikos of Heliopolis, probably about 673. Byzantine texts described weapons, used by Byzantine land forces, which were shooting Greek fire and called cheirosiphona (χειροσίφωνα, meaning hand-held siphons, singular χειροσίφωνο). The flamethrower found its origins in a device consisting of a hand-held pump that shot bursts of Greek fire via a siphon-hose and a piston which ignited it with a match, similar to modern versions, as it was ejected.Needham, Volume 5, 77.

, invented around 919 AD during the Five Dynasties and Ten Kingdoms period. The earliest reference to Greek fire in China was made in 917 AD, written by Wu Renchen in his '' Spring and Autumn Annals of the Ten Kingdoms''.Needham, Volume 5, 80. In 919 CE, the siphon projector-pump was used to spread the ' fierce fire oil' that could not be doused with water, as recorded by Lin Yu (林禹) in his ''Wu-Yue Beishi'' (吳越備史), hence the first credible Chinese reference to the flamethrower employing the chemical solution of Greek fire.Needham, Volume 5, 81. Lin Yu mentioned also that the 'fierce fire oil' derived ultimately from China's contact in the 'southern seas', with Arabia (大食國 ''Dashiguo'').Needham, Volume 5, 82. In the Battle of Langshan Jiang (Wolf Mountain River) in 919, the naval fleet of the Wenmu King of Wuyue defeated the fleet of the Kingdom of Wu because he had used 'fire oil' to burn his fleet; this signified the first Chinese use of gunpowder in warfare, since a slow-burning match fuse was required to ignite the flames. The Chinese applied the use of double- piston bellows to pump petrol out of a single cylinder (with an upstroke and a downstroke), lit at the end by a slow-burning gunpowder match to fire a continuous stream of flame (as referred to in the '' Wujing Zongyao'' manuscript of 1044 AD). In the suppression of the Southern Tang state by 976 AD, early Song naval forces confronted them on the Yangtze River in 975 AD. Southern Tang forces attempted to use flamethrowers against the Song navy, but were accidentally consumed by their own fire when violent winds swept in their direction.Needham, Volume 5, 89. Documented also in later Chinese publications, illustrations and descriptions of mobile flamethrowers on four-wheel push carts appear in the ''Wujing Zongyao'', written in 1044 AD (its illustration redrawn in 1601 as well).

. He submitted evaluation models of his ''Flammenwerfer'' to the German Army in 1901. The most significant model submitted was a portable device, consisting of a vertical single cylinder long, horizontally divided in two, with pressurized gas in the lower section and flammable oil in the upper section. On depressing a lever the propellant gas forced the flammable oil into and through a rubber tube and over a simple igniting wick device in a steel nozzle. The weapon projected a jet of fire and enormous clouds of smoke some . It was a single-shot weapon—for burst firing, a new igniter section was attached each time. Hungarian Gábor Szakáts invented the flamethrower which was first used by the German army in WWI. Szakáts was the only Hungarian on the list of war criminals assembled by France after the war due to the invention of the flamethrower. Even his birthplace Budapest refused to bury Szakáts because of his invention. It was not until 1911 that the German Army accepted their first real flamethrowing device, creating a specialist regiment of twelve companies equipped with Flammenwerfer Apparent. Despite this, use of fire in a World War I battle predated flamethrower use, with a petrol spray being ignited by an incendiary bomb in the Argonne-Meuse sector in October 1914. The flamethrower was first used in World War I on 26 February 1915 when it was briefly used against the French outside Verdun. On 30 July 1915 it was first used in a concerted action, against British trenches at Hooge, where the lines were apart—even there, the casualties were caused mainly by soldiers being flushed into the open and then shot rather than from the fire itself. After two days of fighting the British had suffered casualties of 31 officers and 751 other ranks. The success of the attack prompted the German Army to adopt the device on all fronts. Flamethrowers were used in squads of six during battles, at the start of an attack destroying the enemy and to the preceding the infantry advance. The flamethrower was useful at short distances but had other limitations: it was cumbersome and difficult to operate and could only be safely fired from a trench, which limited its use to areas where the opposing trenches were less than the maximum range of the weapon, namely apart—which was not a common situation; the fuel would also only last for about two minutes.''First World War'', Willmott, H. P., Dorling Kindersley, 2003, p. 106 The German deployed flamethrowers during the war in more than 650 attacks. The British experimented with flamethrowers in the Battle of the Somme, during which they used experimental weapons called " Livens Large Gallery Flame Projectors", named for their inventor, William Howard Livens, a Royal Engineers officer. This weapon was enormous and completely non-portable. The weapon had an effective range of 90 yards, which proved effective at clearing trenches, but with no other benefit the project was abandoned. Two Morriss static flamethrowers were mounted in HMS ''Vindictive'' and several Hay portable flamethrowers were deployed by the Royal Navy during the Zeebrugge Raid on 23 April 1918. A British newspaper report of the action referred to the British flamethrowers only as ''flammenwerfer'', using the German word. The French Army deployed the Schilt family of flamethrowers, which were also used by the Italian Army. The Russian army used 11,446 indigenously produced flamethrowers, over 10,000 of which were the Tovarnitski man-portable design. In the interwar period, at least four flamethrowers were used in the Chaco War by the Bolivian Army, during the unsuccessful assault on the Paraguayan stronghold of Nanawa in 1933.


World War II

The flamethrower was used extensively during
World War II World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the World War II by country, vast majority of the world's countries—including all of the great power ...
. In 1939, the Wehrmacht first deployed man-portable flamethrowers against the Polish Post Office in Danzig. Subsequently, in 1942, the U.S. Army introduced its own man-portable flamethrower. The vulnerability of infantry carrying backpack flamethrowers and the weapon's short range led to experiments with tank-mounted flamethrowers ( flame tanks), which were used by many countries.

Starting in New Guinea, through the closing stages on Guadalcanal and during the approach to and reconquest of the Philippines and then through the Okinawa campaign, the Army deployed hand-held, man-portable units. Often flamethrower teams were made up of combat engineer units, later with troops of the chemical warfare service. The Army fielded more flamethrower units than the Marine Corps, and the Army's Chemical Warfare Service pioneered tank mounted flamethrowers on Sherman tanks (CWS-POA H-4). All the flamethrower tanks on Okinawa belonged to the 713th Provisional Tank Battalion. It was tasked with supporting all U.S. Army and Marine infantry. All Pacific mechanized flamethrower units were trained by Seabee specialists with Col. Unmacht's CWS Flamethrower Group in Hawaii. The U.S. Army used flamethrowers in Europe in much smaller numbers, though they were available for special employments. Flamethrowers were deployed during the Normandy landings in order to clear Axis fortifications. Also, most boat teams on Omaha Beach included a two-man flamethrower team. The Marine Corps used the backpack-type M2A1-7 and M2-2 flamethrowers, finding them useful in clearing Japanese trench and bunker complexes. The first known USMC use of the man portable flamethrower was against the formidable defenses at Tarawa in November 1943. The Marines pioneered the use of Ronson-equipped M-3 Stuart tanks in the Marianas. These were known as SATAN flame tanks. Though effective, they lacked the armour to safely engage fortifications and were phased out in favour of the better-armoured M4 Sherman tanks. USMC Flamethrower Shermans were produced at Schofield Barracks by Seabees attached to the Chemical Warfare Service under Col. Unmacht. CWS designated M4s with "CWS-POA-H" for "Chemical Warfare Service Pacific Ocean Area, Hawaii" plus a flamethrower number. The Marines had previously deployed large Navy flamethrowers mounted on LVT-4 AMTRACs at Peleliu. Late in the war, both services operated LVT-4 and -5 amphibious flametanks in limited numbers. Both the Army and the Marines still used their infantry-portable systems, despite the arrival of adapted Sherman tanks with the Ronson system (cf.

). In cases where the Japanese were entrenched in deep caves, the flames often consumed the available oxygen, suffocating the occupants. Many Japanese troops interviewed post war said they were terrified more by flamethrowers than any other American weapon. Flamethrower operators were often the first U.S. troops targeted.

this was done by disguising the flame projector as a standard issue rifle, such as the Mosin–Nagant, and the fuel tanks as a standard infantryman's rucksack. This was to try to stop the flamethrower operator from being specifically targeted by enemy fire. This "rifle" had a working action which was used to cycle blank igniter cartridges.

The USA and USSR both developed a rocket launcher specifically for the deployment of incendiary munitions, respectively the M202 FLASH and the RPO "Rys" ancestor of the RPO-A Shmel.


Provisional IRA

In the last stages of the Troubles, during the mid-1980s, the IRA smuggled a number of Soviet LPO-50 military flamethrowers (supplied to them by the Libyan government) into Northern Ireland. They used one of these flamethrowers, among other weapons, to storm a British Army permanent checkpoint in Derryard, near Rosslea, on 13 December 1989. Some months later, on 4 March 1990, the IRA attacked an RUC station in Stewartstown, County Tyrone, using an improvised flamethrower consisting of a manure-spreader towed by a tractor to spray 600 imperial gallons (2,700 L) of a petrol/diesel mix to engulf the base in flames, and then opened fire with rifles and an anti-tank rocket launcher.''Fortnight'', No. 283, pp. 20–21.

, County Armagh, during the early 1990s. The first incident occurred on 12 December 1992, when the bunker was manned by Scots Guards, and the second on 12 November 1993. The device used as launcher was also a manure spreader, which doused the facility with fuel, ignited few seconds later by a small explosion. In the 1993 action, a nine-metre-high fireball engulfed the tower for seven minutes. The four Grenadier Guards inside the outpost were rescued by a Saxon armoured vehicle. Incendiary improvised devices were also proven by the republican paramilitaries, like in an IRA grenade attack on a British Army patrol on 4 April 1993 in

In California, unlicensed possession of a flame-throwing device—statutorily defined as "any non-stationary and transportable device designed or intended to emit or propel a burning stream of combustible or flammable liquid a distance of at least " H&W 12750 (a)—is a misdemeanor punishable with a county jail term not exceeding one year ''or'' with a fine not exceeding $10,000 (CA H&W 12761). Licenses to use flamethrowers are issued by the state fire marshal, and they may use any criteria for issuing or not issuing that license which is deemed fit, but must publish those criteria in the California Code of Regulations, Title 11, Section 970 et seq. In the United Kingdom, flamethrowers are "prohibited weapons" under section 5(1)(b) of the Firearms Act 1968 and article 45(1)(f) of the Firearms (Northern Ireland) Order 2004 and possession of a flamethrower would carry a sentence of up to ten years' imprisonment.
