Flamethrower Tank

A flame tank is a type of tank equipped with a flamethrower, most commonly used to supplement combined arms attacks against fortifications, confined spaces, or other obstacles. The type only reached significant use in the Second World War, during which the United States, Nazi Germany, Soviet Union, Italy, Japan, and the United Kingdom all produced flamethrower-equipped tanks.

A number of production methods were used. The flamethrowers used were either modified versions of existing infantry flame weapons (Flammpanzer I and II) or specially designed (Flammpanzer III). They were mounted externally (Flammpanzer II), replaced existing machine gun mounts, or replaced the tank's main armament (Flammpanzer III). Fuel for the flame weapon was either carried inside the tank, in armoured external storage, or in some cases in a special trailer behind the tank ( Churchill Crocodile).

Combat effectiveness

In comparison to man-portable flamethrowers, flame tanks carried much more fuel, and could fire longer-ranged bursts. Due to their ability to get in range of enemy positions in comparative safety, they were invaluable for rooting out heavy infantry fortifications. For example, as the main guns of US tanks were largely unsuccessful in penetrating the thick bunkers created by the Japanese defenders on islands such as Tarawa or Iwo Jima, flame throwing tanks were used instead while infantrymen provided the necessary security during their deployment. On Iwo Jima the marines learned that conventional firearms were relatively ineffective against the Japanese defenders and effectively used flamethrowers and grenades to flush out Japanese troops in the tunnels. One of the technological innovations of the battle, the eight Sherman M4A3R3 medium tanks equipped with flamethrowers (" Ronson" or " Zippo" tanks), proved very effective at clearing Japanese positions. The Shermans were difficult to disable, such that defenders were often compelled to assault them in the open, where they would face the full firepower of marine rifle and machine gun fire.

The maximum range of a flamethrower was typically less than 150 metres. Because of this limitation, the flamethrower was virtually useless on an open battlefield. However, they proved a potent psychological weapon against fortified troops. In many instances, troops surrendered or fled upon seeing a flame tank fire ranging shots, rather than risk being burned alive.

Experience of combat use of flamethrower tanks was mixed. German flamethrower variants of the Panzer II and Panzer III were both discontinued due to unsatisfactory performance and converted into assault guns or tank destroyers. The Panzer IV was never converted into a flame variant, despite having been configured for many other roles.

The mixed results were in part due to the development of infantry anti-tank weapons. At the start of the Second World War most infantry units had weapons with some effectiveness against armoured targets at ranges of thirty to fifty meters, like anti-tank rifles. Towards the end of the war, more powerful anti-tank weapons such as the bazooka, Panzerschreck, and PIAT were introduced which were fatal to tanks at ranges longer than the tank's flamethrower could reach.

British Churchill Crocodiles supported the U.S. Army in the summer of 1944 during the fight over the Normandy hedgerows or the " Bocage country" and used a squadron during the fighting at the Battle for Brest, notably aiding in the defeat of a Fallschirmjäger garrison at the siege of Montbarey fortress on 16 September 1944. The US Army received a smaller American designed flamethrower mounted upon the M4 Sherman tank during the same month of September 1944, assigned to the US Army's 70th Tank Battalion, the flamethrowing tanks went into action on 18 September 1944, where it was found that the weapons had a very short range as compared to the British ''Crocodiles'', and consequently were not very popular amongst US troops.

The Canadian and Dutch armies became two of the most active users of the Wasp variant of the universal carrier equipped with a flamethrower. While fighting in Europe, the Wasp was found to be extremely effective in prying German soldiers from their defenses. Indeed, the mechanical flamethrowers, although not impressive by themselves, struck horror into the minds of German troops, who feared them more than any other conventional weapon. Canadian troops used them during the Battle of the Scheldt.

In contrast to man-portable flamethrowers that were vulnerable to bullets and shrapnel, making them extremely dangerous to their operators, flame tanks were extremely difficult to catch on fire or explode unless hit with an armor piercing round or explosive reaching the ammunition and engine fuel inside the tank's main hull. Tanks such as the Churchill Crocodile, which towed the flamethrower liquid container behind the actual tank, held no greater risk of fire than standard tanks. Although the towed container itself could be easily targeted, the tank and its crew remained well protected. The armored trailer and armored coupling of the Churchill Crocodile could be jettisoned from inside the tank if necessary.

Crews of flame tanks were not necessarily more vulnerable than those in the standard version of the tank (a Churchill Crocodile flame tank being more or less as vulnerable to anti-tank weapons as the standard Churchill), but the crews of flamethrowing tanks were allegedly treated differently should they be captured alive. Due to the perceived inhumanity of the weapon itself, captured crews of such tanks were allegedly treated much less humanely than crews of regular tanks. The allies suspected that there were instances where flametankers were executed by German troops upon capture, and although some published sources claim this was a fact, but not a single specific instance is known to have been documented. Nevertheless, British tank crews received sixpence a day extra "danger money" due to the threat of arbitrary execution. Flame tanks also suffered from the fact, along with flamethrower-armed troops, that all enemy within range would usually fire on them due to the fear of the weapon.

World War I

Some vehicles equipped with flamethrowers were trialed by various nations during World War I, although none were used in combat. Some examples include the Steam Tank and General Jackson's Pedrail prototype.

Interwar period

The successes of the Soviet defense industry, in the late 1920s, made it possible to begin the motorization and mechanization of the Soviet Armed Forces.

In 1932, the Revolutionary Military Council of the USSR adopted a resolution "On giving the mechanized brigade chemical and other means to fight the enemy's entrenched infantry", thereby setting the direction for the design of chemical tanks (flamethrowers were issued to chemical troops). The T-26 tank was chosen as the basis for the chemical tank, which was put into mass production in the USSR in 1931. This armored vehicle, for that period of time, was distinguished by good performance, surpassing foreign tanks in terms of armor and driving performance. The task for the development of a chemical combat vehicle (BKhM-3 / KhT-26) was assigned to the Military Chemical Directorate (VOKHIMU) of the Red Army, in turn, VOKHIM, entrusted this work to KB-2 of plant No. 174 in Leningrad and the design bureau of the Kompressor plant (chemical equipment). BKhM-3, in addition to the flamethrower, was equipped with smoke launchers and toxic sprays, so these tanks were called not flamethrower, but "chemical".

The first combat-ready flamethrower tanks appeared in the early 1930s: KhT-27, KhT-26 and a number of others - in the USSR, CV3 LF - in Italy. Before the start of World War II more than 1,300 flamethrower tanks of various types were produced by Soviet industry.A. N. Ardashev, S. L. Fedoseev. ''Flamethrower tanks of World War II''. - M .: Armor collection, special issue No. 8, 2005, page 3

By the mid-1930s, the first combat use of flamethrower tanks took place. Italy used its flamethrower tanks in the Second Italo-Ethiopian War of 1935-1936, and the CV3 LF was also used by the Italian Expeditionary Force during the Spanish Civil War.
Soviet troops first used flamethrower tanks against the Japanese at Khasan in 1938 and later a Khalkhin Gol in 1939.

In 1931 the São Paulo Public Force created an assault car section. The first vehicle to be incorporated was a flame tank built from a Caterpillar Twenty Two Tractor. The vehicle was developed by lieutenant Reynaldo Ramos de Saldanha da Gama, with help from the Polytechnic school. It was built from riveted steel plates, with a rotating flamethrower turret, and four 7mm Hotchkiss machineguns mounted on the hull. The Flamethrowers' effective range was a hundred meters. The tank was used in combat during the Constitutionalist Revolution, routing federal troops from a bridge in an engagement at Cruzeiro.

During the battle of Kilometer 7 to Saavedra in the Chaco War, Major Walther Kohn rode in a flamethrower equipped tankette; due to heat he exited the tank to fight on foot and was killed in combat.

Post–Cold War and 21st century

Since 1978, flamethrowers and the last flame 'tank' the M132 armored flamethrower have not been part of the US arsenal. Though not banned, these weapons have fallen out of use and have instead been replaced with non-flamethrower incendiary weapons like thermobaric weapons which may have been fielded in Afghanistan by the United States in 2009 and by Russia in the 2022 Russo-Ukrainian war.
