122-498: A tank is an armoured fighting vehicle intended as a primary offensive weapon in front-line ground combat . Tank designs are a balance of heavy firepower , strong armour , and battlefield mobility provided by tracks and a powerful engine; their main armament is often mounted within a turret . They are a mainstay of modern 20th and 21st century ground forces and a key part of combined arms combat. Modern tanks are versatile mobile land weapons platforms whose main armament
244-433: A diesel engine ; modern technology, including the use of turbo-charging , helps to overcome the lower power-to-weight ratio of diesel engines compared to petrol. Gas turbine (turboshaft) engines offer a very high power-to-weight ratio and were starting to find favour in the late 20th century – however, they offer very poor fuel consumption and as such some armies are switching from gas turbines back to diesel engines (i.e.
366-447: A main battle tank will normally be designed to take hits from other tank guns and anti-tank missiles , whilst light reconnaissance vehicles are often only armoured "just in case". Whilst heavier armour provides better protection, it makes vehicles less mobile (for a given engine power), limits its air-transportability, increases cost, uses more fuel and may limit the places it can go – for example, many bridges may be unable to support
488-494: A turret or cupola. The greater the recoil of the weapon on an AFV, the larger the turret ring needs to be. A larger turret ring necessitates a larger vehicle. To avoid listing to the side, turrets on amphibious vehicles are usually located at the centre of the vehicle. Grenade launchers provide a versatile launch platform for a plethora of munitions including, smoke , phosphorus, tear gas , illumination, anti-personnel, infrared and radar-jamming rounds. Turret stabilization
610-726: A British Army engineer. They were very popular with smaller countries. Some saw some combat (with limited success) in World War II. However, the vulnerability of their light armour eventually caused the concept to be abandoned. However, the German Army uses a modern design of air-transportable armoured weapons carriers, the Wiesel AWC , which resembles the concept of a tankette. The term "super-heavy tank" has been used to describe armoured fighting vehicles of extreme size, generally over 75 tonnes. Programs have been initiated on several occasions with
732-747: A Vickers QF-1 "Pom-Pom" gun of 40 mm. The Germans fielded the Sd.Kfz. 10/4 and 6/2, cargo halftracks mounting single 20 mm or 37 mm AA guns (respectively) by the start of the war. Rocket launchers such as the Soviet Katyusha originated in the late 1930s. The Wehrmacht fielded self-propelled rocket artillery in World War II – the Panzerwerfer and Wurfrahmen 40 equipped half-track armoured fighting vehicles. Many modern multiple rocket launchers are self propelled by either truck or tank chassis. The level of armour protection between AFVs varies greatly –
854-612: A caterpillar track. It is true that in 1770 he patented a "machine, that should carry and lay down its own road", but this was Edgeworth's choice of words. His own account in his autobiography is of a horse-drawn wooden carriage on eight retractable legs, capable of lifting itself over high walls. The description bears no similarity to a caterpillar track. Armoured trains appeared in the mid-19th century, and various armoured steam and petrol-engined vehicles were also proposed. The machines described in Wells's 1903 short story The Land Ironclads are
976-635: A commission was placed to design a machine that could cross a trench 4 ft wide. Secrecy surrounded the project with the designers locking themselves in a room at the White Hart Hotel in Lincoln. The committee's first design, Little Willie , ran for the first time in September 1915 and served to develop the form of the track but an improved design, better able to cross trenches, swiftly followed and in January 1916
1098-525: A fellow of the Royal Historical Society * has unintentionally misled the British public as to the origin of the famous "tanks", Sir William Tritton , who designed and built them, has published the real story of their name ... Since it was obviously inadvisable to herald "Little Willie's" reason for existence to the world he was known as the "Instructional Demonstration Unit." "Little Willie's" hull
1220-511: A field gun in an armoured box on tracks . Major William E. Donohue, of the British Army's Mechanical Transport Committee, suggested fixing a gun and armoured shield on a British type of track-driven vehicle. The first armoured car was produced in Austria in 1904. However, all were restricted to rails or reasonably passable terrain. It was the development of a practical caterpillar track that provided
1342-435: A highly mobile and protected fighting unit has been around for centuries; from Hannibal 's war elephants to Leonardo 's contraptions , military strategists endeavoured to maximize the mobility and survivability of their soldiers. Armoured fighting vehicles were not possible until internal combustion engines of sufficient power became available at the start of the 20th century. Modern armoured fighting vehicles represent

So tanks they became, and tanks they have remained." This appears to be an imperfect recollection. He says that the name problem arose "when we shipped the first two vehicles to France the following year" (August 1916), but by that time
1586-468: A light, three-man tank with a gun in a revolving turret, the so-called Burstyn-Motorgeschütz. In the same year an Australian civil engineer named Lancelot de Mole submitted a basic design for a tracked, armoured vehicle to the British War Office . In Russia, Vasiliy Mendeleev designed a tracked vehicle containing a large naval gun. All of these ideas were rejected and, by 1914, forgotten (although it
1708-769: A meeting took place of the Inter-Departmental Conference (including representatives of the Director of Naval Construction's Committee, the Admiralty, the Ministry of Munitions, and the War Office). Its purpose was to discuss the progress of the plans for what were described as "Caterpillar Machine Gun Destroyers or Land Cruisers." In his autobiography, Albert Gerald Stern (Secretary to the Landship Committee, later head of

Blitzkrieg used innovative combined arms tactics and radios in all of the tanks to provide a level of tactical flexibility and power that surpassed that of the Allied armour. The French Army , with tanks equal or superior to
1952-428: A new era of combat, armoured warfare . Until the invention of the main battle tank , tanks were typically categorized either by weight class ( light , medium , heavy or superheavy tanks ) or doctrinal purpose ( breakthrough- , cavalry- , infantry- , cruiser- , or reconnaissance tanks). Some are larger and more thickly armoured and with large guns, while others are smaller, lightly armoured, and equipped with
2074-528: A non-committal word when writing his report of the proceedings. In the evening he discussed it with a fellow officer, Lt-Col Walter Dally Jones , and they chose the word "tank". "That night, in the draft report of the conference, the word 'tank' was employed in its new sense for the first time." Swinton's Notes on the Employment of Tanks , in which he uses the word throughout, was published in January 1916. In July 1918, Popular Science Monthly reported: Because

However leading roles were played by Lt Walter Gordon Wilson R.N. who designed the gearbox and developed practical tracks and by William Tritton whose agricultural machinery company, William Foster & Co. in Lincoln, Lincolnshire , England built the prototypes . On 22 July 1915,
2318-619: A repeat of the German successes of 1940. Despite early successes against the Soviets, the Germans were forced to up-gun their Panzer IVs, and to design and build both the larger and more expensive Tiger heavy tank in 1942, and the Panther medium tank the following year. In doing so, the Wehrmacht denied the infantry and other support arms the production priorities that they needed to remain equal partners with
2440-592: A revolution. In August 1939, Soviet General Georgy Zhukov used the combined force of tanks and airpower at Nomonhan against the Japanese 6th Army; Heinz Guderian , a tactical theoretician who was heavily involved in the formation of the first independent German tank force, said "Where tanks are, the front is", and this concept became a reality in World War II. Guderian's armoured warfare ideas, combined with Germany's existing doctrines of Bewegungskrieg (" maneuver warfare ") and infiltration tactics from World War I, became
2562-490: A smaller caliber and lighter gun. These smaller tanks move over terrain with speed and agility and can perform a reconnaissance role in addition to engaging hostile targets. The smaller, faster tank would not normally engage in battle with a larger, heavily armoured tank, except during a surprise flanking manoeuvre . The word tank was first applied in a military context to British "landships" in 1915 to keep their nature secret before they entered service. On 24 December 1915,

Some aspects of the story foresee the tactical use and impact of the tanks that later came into being. However, Wells's vehicles were driven by steam and moved on pedrail wheels , technologies that were already outdated at the time of writing. After seeing British tanks in 1916, Wells denied having "invented" them, writing, "Yet let me state at once that I
2806-467: A tank being first deployed as a medium tank, but in later years relegated to light tank roles. Tanks were also classified by roles that were independent of size, such as cavalry tank , cruiser tank , fast tank , infantry tank , "assault" tank, or "breakthrough" tank. Military theorists initially tended to assign tanks to traditional military infantry, cavalry, and artillery roles, but later developed more specialized roles unique to tanks. In modern use,
2928-414: A tank chassis. During World War II, most major military powers developed self-propelled artillery vehicles. These had guns mounted on a tracked chassis (often that of an obsolete or superseded tank) and provided an armoured superstructure to protect the gun and its crew. The first British design, "Bishop" , carried the 25 pdr gun-howitzer in an extemporised mounting on a tank chassis that severely limited
3050-446: A very large movable siege tower, the helepolis , as early as 340 BC, and Greek forces used such structures in the Siege of Rhodes (305 BC). The idea of a protected fighting vehicle has been known since antiquity. Frequently cited is Leonardo da Vinci 's 15th-century sketch of a mobile, protected gun-platform ; the drawings show a conical, wooden shelter with apertures for cannons around

Despite significant advances in anti-tank warfare , it still remains the most versatile and fearsome land-based weapon-systems of the 21st-century, valued for its shock action and high survivability . A tankette is a tracked armed and armoured vehicle resembling a small "ultra-light tank" or "super-light tank" roughly the size of a car, mainly intended for light infantry support or scouting . Tankettes were introduced in

They have heavy vehicle armour which provides protection for the crew, the vehicle's munition storage, fuel tank and propulsion systems. The use of tracks rather than wheels provides improved operational mobility which allows
3416-616: Is a tank fulfilling the role of a main battle tank, but using only anti-tank surface-to-surface missiles for main armament. Several nations have experimented with prototypes, notably the Soviet Union during the tenure of Nikita Khrushchev (projects Object 167, Object 137Ml, Object 155Ml, Object 287, Object 775), A flame tank is an otherwise-standard 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

In Hungarian the tank is called harckocsi (combat wagon), albeit tank is also common. In Japanese, the term sensha ( 戦車 , lit. "battle vehicle") is taken from Chinese and used, and this term is likewise borrowed into Korean as jeoncha ( 전차 / 戰車 ); more recent Chinese literature uses

More recently, gas turbines have been used. Most early AFVs used petrol engines , as they offer a good power-to-weight ratio . However, they fell out of favour during World War II due to the flammability of the fuel. Most current AFVs are powered by

In the 21st century, with the increasing role of asymmetrical warfare and the end of the Cold War, that also contributed to the increase of cost-effective anti-tank rocket propelled grenades (RPGs) worldwide and its successors, the ability of tanks to operate independently has declined. Modern tanks are more frequently organized into combined arms units which involve

These heavy wagons were given protective sides with firing slits; their heavy firepower came from either a cannon or from a force of hand-gunners and crossbowmen , supported by light cavalry and infantry using pikes and flails . Heavy arquebuses mounted on wagons were called arquebus à croc . These carried a ball of about 3.5 ounces (100 g). By the end of World War II , most modern armies had vehicles to carry infantry, artillery and anti-aircraft weaponry . Most modern AFVs are superficially similar in design to their World War II counterparts, but with significantly better armour, weapons, engines, electronics, and suspension. The increase in

In addition, they lacked radios in many of their tanks and headquarters, which limited their ability to respond to German attacks. In accordance with blitzkrieg methods, German tanks bypassed enemy strongpoints and could radio for close air support to destroy them, or leave them to

9272-416: The future arrangements were under discussion for transporting the first landships to France a question arose as to how, from a security point of view, the consignment should be labelled. To justify their size we decided to call them 'water-carriers for Russia' —the idea being that they should be taken for some new method of taking water to forward troops in the battle areas. Lt.-Col. Swinton ... raised
9394-438: The gearbox and hull, and by William Tritton of William Foster and Co. , who designed the track plates. This was a prototype of a new design that would become the British Army's Mark I tank , the first tank used in combat in September 1916 during the Battle of the Somme . The name "tank" was adopted by the British during the early stages of their development, as a security measure to conceal their purpose (see etymology ). While
9516-674: The gun's performance. It was replaced by the more effective Sexton . The Germans built many lightly armoured self-propelled anti-tank guns using captured French equipment (for example Marder I ), their own obsolete light tank chassis ( Marder II ), or ex-Czech chassis ( Marder III ). These led to better-protected tank destroyers, built on a medium-tank chassis such as the Jagdpanzer IV or the Jagdpanther . The Self-propelled anti-aircraft weapon debuted in WWI. The German 88 mm anti-aircraft gun
9638-400: The heavy tank has fallen out of favour, being supplanted by more heavily armed and armoured descendant of the medium tanks – the universal main battle tank . The light tank has, in many armies, lost favour to cheaper, faster, lighter armoured cars ; however, light tanks (or similar vehicles with other names) are still in service with a number of forces as reconnaissance vehicles , most notably
9760-571: The increasingly sophisticated tanks, in turn violating the principle of combined arms they had pioneered. Soviet developments following the invasion included upgunning the T-34, development of self-propelled anti-tank guns such as the SU-152 , and deployment of the IS-2 in the closing stages of the war, with the T-34 being the most produced tank of World War II, totalling up to some 65,000 examples by May 1945. Much like
9882-494: The individual vehicle too, depending on the role of the vehicle and the likely direction of attack. For example, a main battle tank will usually have the heaviest armour on the hull front and the turret, lighter armour on the sides of the hull and the thinnest armour on the top and bottom of the tank. Other vehicles – such as the MRAP family – may be primarily armoured against the threat from IEDs and so will have heavy, sloped armour on
10004-451: The infantry. A related development, motorized infantry , allowed some of the troops to keep up with the tanks and create highly mobile combined arms forces. The defeat of a major military power within weeks shocked the rest of the world, spurring tank and anti-tank weapon development. The North African Campaign also provided an important battleground for tanks, as the flat, desolate terrain with relatively few obstacles or urban environments
10126-424: The insistence of Colonel J.B.E. Estienne , rejected in favour of char d'assaut ("assault vehicle") or simply char ("vehicle"). During World War I, German sources tended to refer to British tanks as tanks and to their own as Kampfwagen . Later, tanks became referred to as " Panzer " (lit. "armour"), a shortened form of the full term " Panzerkampfwagen ", literally "armoured fighting vehicle". In
10248-505: The intense heat and noxious atmosphere. In 1917, Lieutenant G. J. Rackham was ordered to design an armoured vehicle that could fight and carry troops or supplies. The Mark IX tank was built by Armstrong, Whitworth & Co. , although just three vehicles had been finished at the time of the Armistice in November 1918, and only 34 were built in total. Different tank classifications emerged in
10370-706: The interwar period. The tankette was conceived as a mobile, two-man model, mainly intended for reconnaissance. In 1925, Sir John Carden and Vivian Loyd produced the first such design to be adopted – the Carden Loyd tankette . Tankettes saw use in the Royal Italian Army during the Italian invasion of Ethiopia (1935–1936), the Spanish Civil War (1936–1939), and almost everywhere Italian soldiers fought during World War II . The Imperial Japanese Army used tankettes for jungle warfare . The British Gun Carrier Mark I ,
10492-867: The introduction of laser rangefinders and infrared night vision equipment. Armour technology progressed in an ongoing race against improvements in anti-tank weapons , especially antitank guided missiles like the TOW . Armoured fighting vehicle An armoured fighting vehicle ( British English ) or armored fighting vehicle ( American English ) ( AFV ) is an armed combat vehicle protected by armour , generally combining operational mobility with offensive and defensive capabilities. AFVs can be wheeled or tracked . Examples of AFVs are tanks , armoured cars , assault guns , self-propelled artilleries , infantry fighting vehicles (IFV), and armoured personnel carriers (APC). Armoured fighting vehicles are classified according to their characteristics and intended role on
10614-474: The mid-1920s as a reconnaissance vehicle and a mobile machine gun position They were one or two-man vehicles armed with a machine gun. Colloquially it may also simply mean a "small tank". Tankettes were designed and built by several nations between the 1920s and 1940s following the British Carden Loyd tankette which was a successful implementation of "one man tank" ideas from Giffard Le Quesne Martel ,
10736-591: The modern tank. During the 119 BC Battle of Mobei of the Han–Xiongnu War , the Han general Wei Qing led his army through a fatiguing expeditionary march across the Gobi desert only to find Yizhixie chanyu 's main force waiting to encircle them on the other side. Using armored heavy wagons known as "Wu Gang Wagon" ( Chinese : 武剛車) in ring formations that provided Chinese archers , crossbowmen and infantry protection from
10858-411: The muddy, pocked terrain and slit trenches of the Battle of the Somme . The tank eventually proved highly successful and, as technology improved, it became a weapon that could cross large distances at much higher speeds than supporting infantry and artillery . The need to provide the units that would fight alongside the tank led to the development of a wide range of specialised AFVs, especially during
10980-464: The name "tank" had been in use for eight months. The tanks were labelled "With Care to Petrograd," but the belief was encouraged that they were a type of snowplough. The term "tank" is used throughout the English speaking world, but other countries use different terminology. In France, the second country to use tanks in battle, the word tank or tanque was adopted initially, but was then, largely at
11102-400: The near invulnerability to common infantry small arms and good resistance against heavier weapons, although anti-tank weapons used in 2022, some of them man-portable, have demonstrated the ability to destroy older generations of tanks with single shots), all while maintaining the mobility needed to exploit changing tactical situations. Fully integrating tanks into modern military forces spawned
11224-899: The necessary independent, all-terrain mobility. In a memorandum of 1908, Antarctic explorer Robert Falcon Scott presented his view that man-hauling to the South Pole was impossible and that motor traction was needed. Snow vehicles did not yet exist, however, and so his engineer Reginald Skelton developed the idea of a caterpillar track for snow surfaces. These tracked motors were built by the Wolseley Tool and Motor Car Company in Birmingham and tested in Switzerland and Norway, and can be seen in action in Herbert Ponting 's 1911 documentary film of Scott's Antarctic Terra Nova Expedition . Scott died during
11346-484: The opposing force who can often hear and even feel their arrival. Tanks were classified either by size or by role. Classification by relative size was common, as this also tended to influence the tanks' role. Over time, tanks tended to be designed with heavier armour and weapons, increasing the weight of all tanks, so these classifications are relative to the average for the nation's tanks for any given period. An older tank design might be reclassified over time, such as
11468-420: The proposed title totally unsuitable. In our search for a synonymous term, we changed the word "Water Carrier" to "Tank," and became the "Tank Supply" or "T.S." Committee. That is how these weapons came to be called Tanks. He incorrectly added, "and the name has now been adopted by all countries in the world." Lieutenant-Colonel Ernest Swinton, who was secretary to the meeting, says that he was instructed to find
11590-491: The prototype, nicknamed "Mother", was adopted as the design for future tanks. The first order for tanks was placed on 12 February 1916, and a second on 21 April. Fosters built 37 (all "male"), and Metropolitan Railway Carriage and Wagon Company , of Birmingham, 113 (38 "male" and 75 "female"), a total of 150. Production models of "Male" tanks (armed with naval cannon and machine guns) and "Females" (carrying only machine-guns) would go on to fight in history's first tank action at
11712-527: The realization of an ancient concept – that of providing troops with mobile protection and firepower. Armies have deployed war machines and cavalries with rudimentary armour in battle for millennia. Use of these animals and engineering designs sought to achieve a balance between the conflicting paradoxical needs of mobility, firepower and protection. Siege engines , such as battering rams and siege towers , would often be armoured in order to protect their crews from enemy action. Polyidus of Thessaly developed
11834-574: The second half of World War II led to lightweight infantry-carried anti-tank weapons such as the Panzerfaust , which could destroy some types of tanks. Tanks in the Cold War were designed with these weapons in mind, and led to greatly improved armour types during the 1960s, especially composite armour . Improved engines, transmissions and suspensions allowed tanks of this period to grow larger. Aspects of gun technology changed significantly as well, with advances in shell design and aiming technology. During
11956-496: The successful use of combined arms allowed the Allies to overrun the German forces during the Battle of Normandy . Upgunned versions with the 76 mm gun M1 and the 17-pounder were introduced to improve the M4's firepower, but concerns about protection remained—despite the apparent armour deficiencies, a total of some 42,000 Shermans were built and delivered to the Allied nations using it during
12078-401: The support of infantry , who may accompany the tanks in infantry fighting vehicles , and supported by reconnaissance or ground-attack aircraft . The tank is the 20th-century realization of an ancient concept: that of providing troops with mobile protection and firepower. The internal combustion engine , armour plate , and continuous track were key innovations leading to the invention of
12200-409: The tank in World War I, and the tank did not fulfil its promise of rendering trench warfare obsolete. Nonetheless, it was clear to military thinkers on both sides that tanks in some way could have a significant role in future conflicts. In the interwar period tanks underwent further mechanical development. In terms of tactics, J.F.C. Fuller 's doctrine of spearhead attacks with massed tank formations
12322-439: The tank is, by its very nature, an offensive weapon. Being a protective encasement with at least one gun position, it is essentially a pillbox or small fortress (though these are static fortifications of a purely defensive nature) that can move toward the enemy – hence its offensive utility. Psychologically, the tank is a force multiplier that has a positive morale effect on the infantry it accompanies. It also instills fear in
12444-444: The tank to overcome rugged terrain and adverse conditions such as mud and ice/snow better than wheeled vehicles, and thus be more flexibly positioned at advantageous locations on the battlefield. These features enable the tank to perform in a variety of intense combat situations, simultaneously both offensively (with direct fire from their powerful main gun) and defensively (as fire support and defilade for friendly troops due to
12566-597: The tank, although a few designs mounted the fuel externally, such as the armoured trailer used on the Churchill Crocodile . Flame tanks have been superseded by thermobaric weapons such as the Russian TOS-1 . The idea for this tank was developed during World War I by British and French. The infantry tank was designed to work in concert with infantry in the assault, moving mostly at a walking pace, and carrying heavy armour to survive defensive fire. Its main purpose
12688-444: The tank. Leonardo's late-15th-century drawings of what some describe as a "tank" show a man-powered, wheeled vehicle surrounded by cannons. However, the human crew would have difficulty moving the heavy vehicle over long distances, while usage of animals was problematic in a space so confined. In the 15th century, Jan Žižka built armoured wagons known as ‘ Wagenburg ’ containing cannons and used them effectively in several battles during
12810-470: The war years, a total second only to the T-34. Tank hulls were modified to produce flame tanks , mobile rocket artillery , and combat engineering vehicles for tasks including mine-clearing and bridging . Specialized self-propelled guns, most of which could double as tank destroyers , were also both developed by the Germans—with their Sturmgeschütz , Panzerjäger and Jagdpanzer vehicles—and
12932-420: The war, too late to see service. Russia independently built and trialed two prototypes early in the War; the tracked, two-man Vezdekhod and the huge Lebedenko , but neither went into production. A tracked self-propelled gun was also designed but not produced. Although tank tactics developed rapidly during the war, piecemeal deployments, mechanical problems, and poor mobility limited the military significance of
13054-475: The weight of a main battle tank. A trend toward composite armour is taking the place of steel – composites are stronger for a given weight, allowing the tank to be lighter for the same protection as steel armour, or better protected for the same weight. Armour is being supplemented with active protection systems on a number of vehicles, allowing the AFV to protect itself from incoming projectiles. The level of protection also usually varies considerably throughout
13176-471: The years since their first appearance. Tanks in World War I were developed separately and simultaneously by Great Britain and France as a means to break the deadlock of trench warfare on the Western Front . The first British prototype, nicknamed Little Willie , was constructed at William Foster & Co. in Lincoln , England in 1915, with leading roles played by Major Walter Gordon Wilson who designed
13298-606: Was a colonel of artillery, J.B.E. Estienne , who directly approached the Commander-in-Chief with detailed plans for a tank on caterpillar tracks, in late 1915. The result was two largely unsatisfactory types of tank, 400 each of the Schneider and Saint-Chamond , both based on the Holt tractor . The following year, the French pioneered the use of a full 360° rotation turret in a tank for
13420-466: Was called in the shop orders a "water carrier for Mesopotamia"; no one knew that the hull was intended to be mounted on a truck. Naturally, the water carrier began to be called a "tank". So the name came to be used by managers and foremen of the shop, until now it has a place in the army vocabulary and will probably be so known in history for all time. (*F.J. Gardiner, F.R.Hist.S.) D'Eyncourt's account differs from Swinton's and Tritton's: ... when
13542-442: Was equipped with a Hotchkiss machine gun , and with 7 mm armour for the gunner. Armoured cars were first used in large numbers on both sides during World War I as scouting vehicles. In 1903, H. G. Wells published the short story " The Land Ironclads ," positing indomitable war machines that would bring a new age of land warfare, the way steam-powered ironclad warships had ended the age of sail . Wells's literary vision
13664-546: Was ideal for conducting mobile armoured warfare. However, this battlefield also showed the importance of logistics, especially in an armoured force, as the principal warring armies, the German Afrika Korps and the British Eighth Army , often outpaced their supply trains in repeated attacks and counter-attacks on each other, resulting in complete stalemate. This situation would not be resolved until 1942, when during
13786-497: Was not their prime originator. I took up an idea, manipulated it slightly, and handed it on." It is, though, possible that one of the British tank pioneers, Ernest Swinton , was subconsciously or otherwise influenced by Wells's tale. The first combinations of the three principal components of the tank appeared in the decade before World War One. In 1903, Captain Léon René Levavasseur of the French artillery proposed mounting
13908-416: Was officially acknowledged after the war that de Mole's design was at least the equal to the initial British tanks). Various individuals continued to contemplate the use of tracked vehicles for military applications, but by the outbreak of the War no one in a position of responsibility in any army seems to have given much thought to tanks. The direct military impact of the tank can be debated but its effect on
14030-591: Was powered by a four-cylinder 3.3-litre 16 hp Cannstatt Daimler engine giving it a maximum speed of around 9 miles per hour (14 kilometres per hour). The armament, consisting of two Maxim guns, was carried in two turrets with 360° traverse. Another early armoured car of the period was the French Charron, Girardot et Voigt 1902 , presented at the Salon de l'Automobile et du cycle in Brussels , on 8 March 1902. The vehicle
14152-629: Was realized in 1916, when, amidst the pyrrhic standstill of the Great War , the British Landship Committee deployed revolutionary armoured vehicles to break the stalemate. The tank was envisioned as an armoured machine that could cross ground under fire from machine guns and reply with its own mounted machine guns and naval artillery . These first British tanks of World War I moved on caterpillar tracks that had substantially lower ground pressure than wheeled vehicles, enabling them to pass
14274-472: Was recognized as the most effective mounting for the main gun to allow movement in a different direction from firing, enhancing tactical flexibility. During the Cold War , tension between the Warsaw Pact countries and North Atlantic Treaty Organization ( NATO ) countries created an arms race that ensured that tank development proceeded largely as it had during World War II. The essence of tank designs during
14396-628: Was the basis for work by Heinz Guderian in Germany, Percy Hobart in Britain, Adna R. Chaffee, Jr. , in the US, Charles de Gaulle in France, and Mikhail Tukhachevsky in the USSR. Liddell Hart held a more moderate view that all arms – cavalry, infantry and artillery – should be mechanized and work together. The British formed the all-arms Experimental Mechanized Force to test the use of tanks with supporting forces. In
14518-578: Was the first armed, petrol-engine powered vehicle ever built. It consisted of a De Dion-Bouton quadracycle with a Maxim machine gun mounted on the front bar. An iron shield offered some protection for the driver from the front, but it lacked all-around protective armour. The armoured car was the first modern fully armoured fighting vehicle. The first of these was the Simms's Motor War Car , also designed by Simms and built by Vickers, Sons & Maxim in 1899. The vehicle had Vickers armour 6 mm thick and
14640-560: Was the most numerous tank of the war; over 3,000 were made by late 1918. Germany fielded very few tanks during World War I , and started development only after encountering British tanks on the Somme. The A7V , the only type made, was introduced in March 1918 with just 20 being produced during the war. The first tank versus tank action took place on 24 April 1918 at the Second Battle of Villers-Bretonneux , France, when three British Mark IVs met three German A7Vs . Captured British Mk IVs formed
14762-499: Was to suppress enemy fire, crush obstacles such as barbed-wire entanglements, and protect the infantry on their advance into and through enemy lines by giving mobile overwatch and cover . The French Renault FT was the first iteration of this concept. The British and French retained the concept between the wars and into the Second World War era. Because infantry tanks did not need to be fast, they could carry heavy armour. One of
14884-544: Was truck-mounted and used to great effect against British tanks, and the British QF 3-inch 20 cwt was mounted on trucks for use on the Western Front . Although the Birch gun was a general purpose artillery piece on an armoured tracked chassis, it was capable of elevation for anti-aircraft use. Vickers Armstrong developed one of the first SPAAGs based on the chassis of the Mk.E 6-ton light tank/ Dragon Medium Mark IV tractor , mounting
