s which they met accidentally. After the final German spring offensives of 21 March to 18 July 1918, the Entente deployed tanks ''en masse'' at the Battle of Soissons (18 to 22 July 1918) and Battle of Amiens (August 1918), which ended the stalemate imposed by trench warfare on the Western Front, and thus effectively ended the war. Tactically, deployment plans for armour during the war typically placed a strong emphasis on direct support for infantry. The tank's main tasks were seen as crushing barbed-wire and destroying machine-gun nests, facilitating the advance of foot soldiers. Theoretical debate largely focused on the question of whether to use a "swarm" of light tanks for this, or a limited number of potent heavy vehicles. Though in the Battle of Cambrai a large concentration of British heavy tanks effected a breakthrough, it was not exploited by armour. The manoeuvrability of the tank should at least in theory regain armies the ability to

enemy lines. In practice, tank warfare during most of World War I was hampered by the technical immaturity of the new weapon system, limiting speed, operational range, and reliability, and a lack of effective armoured tactics. Strategic use of tanks developed only slowly during and immediately after World War I, partly due to these technical limits but also due to the prestige role traditionally accorded to horse-mounted cavalry. An exception, on paper, was the

of the British Army's Colonel John Fuller, who envisaged using the expected vast increase in armour production during 1919 to execute deep strategic penetrations by mechanised forces consisting of tanks and infantry carried by trucks, supported by aeroplanes, to paralyse the enemy command-structure. Following the First World War, the technical and doctrinal aspects of armoured warfare became more sophisticated and diverged into multiple schools of doctrinal thought.

in general, were extremely unreliable, and could not be used in sustained operations. Mainstream thought on the subject was more conservative and tried to integrate armoured vehicles into the existing infantry and cavalry organisation and tactics. Technical development initially focussed on the improvement of the suspension system, transmission and engine, to create vehicles that were faster, more reliable and had a better range than their WW I predecessors. To save weight, such designs had thin armour plating and this inspired fitting small-calibre high-velocity guns in turrets, giving tanks a good antitank capacity. Both France and Britain eventually built specialised infantry tanks, more heavily armoured to provide infantry support, and cavalry tanks that were faster and could exploit a breakthrough, seeking to bring about defeat of the enemy by severing his lines of communication and supply, as cavalry had done during the previous century. The British were the first to create a larger fully mechanised unit when the

and France began to rearm in the early thirties. In the Soviet Union, the mechanisation of the armed forces was part of a massive general industrialisation programme, the successive Five Years Plans, and the country soon had more tanks than the rest of the world combined, thousands of them being produced per year. In this period, before the rise to power of the Nazi Party in Germany, German officers were sent to observe and participate in development of armoured doctrine in the USSR.

s. As the mechanisation progressed, slowly the French armour doctrine began to reflect the increased capacity, evolving from direct infantry support, to independent breakthrough and eventually envelopment with the Infantry, and to deep strategic exploitation with the Cavalry. Despite the increase in tank numbers, in all countries financial constraints prohibited a full mechanisation of the entire armed ground forces. Necessarily, most of the divisions still consisted of infantry that was not even motorised. As a result, tanks tended to be allotted to special armoured units, where the limited and expensive expert maintenance and training capacity could be concentrated. Only the Soviet Union had enough tanks to equip an organic tank battalion in each infantry division. Nevertheless, France was the first to create large armoured units: in 1934 two Mechanised Corps were formed of 430 tanks each. In July 1935, in France the 4th Cavalry Division was transformed into the '' 1e Division Légère Mécanique'', the first French armoured division of the Cavalry. In Germany, after the

but these proved to be vulnerable to antitank guns due to their thin armour. Traditionalist elements within the Red Army used this to diminish the influence of proponents of mechanisation.

Poland

In their

during September 1939, German forces applied a narrow cooperation between large armoured units — of the ''Panzerwaffe'' and the Cavalry — and "active" infantry divisions to break the Polish defensive lines and pursue the defeated enemy forces. The more limited and dispersed Polish armoured units were quickly destroyed. The Red Army, invading the east of Poland, also deployed armoured divisions. At the time, the swift collapse of the Polish army was seen as the result of an armoured ''Blitzkrieg''. However, later it has been argued that the campaign was largely an instance of the classical nineteenth century German concept of the "Annihilation Battle", in which the role of deep strategic armoured penetrations was limited.

French, British and German tank production sharply increased, with both western allies out-producing Germany. However, the Anglo-French coalition proved unable to match the Germans in the number of armoured divisions, as it was impossible to quickly raise such large units. Though the French possessed a superior number of tanks, often better armoured and armed, half of these were allotted at army-level to independent ''Bataillons de Chars de Combat'' ("battle tank battalions") for infantry support. In early 1940, the German command had concluded that it could not win a war of attrition and embarked on a high-risk strategy. They approved the

Pre-war

Much of the Red Army development in tank use was based on the theoretical work carried out by such officers as Tukhachevsky and Triandafillov in the mid to late 1930s. This was as part of the two-directioned concepts, one being infantry-centred "broad front" and the other being a "shock army". While the infantry based part of the doctrine demanded "powerful tanks" (heavy tanks armed with infantry guns and machineguns) and "tankettes" (light, often amphibious tanks with machineguns), the shock army demanded "manoeuvre tanks" (fast tanks with medium guns) used in conjunction with motorised forces and "mechanised cavalry" that would operate in depth as "strategic cavalry" combined with nascent airborne troops. These ideas culminated in the "PU-36" or the 1936 Field Service Regulations.

Germany

In Germany, in-depth research through theoretical approaches, wargaming and exercises developed a confidence within the '' Panzertruppe'' itself (and political support by Hitler) in the armoured formation as the key battlefield formation — although this view was before 1940 not shared by the other Arms of Service. A key part of this doctrine was improved communications by having radios in all tanks, although this ideal suffered from technical limits as most tanks had receiver sets only. At the outbreak of World War II, the German armoured forces benefited from a much more profound and more flexible training than that of the Allies on the tactical and operational level. German tanks operated while directed by radio communication, which allowed tank commanders to take greater advantage of the manoeuvrability of their vehicles. Even after the conquest of Poland, "Blitzkrieg" was not defined on the strategic level. Guderian and von Manstein devised a strategy that entailed what later would be seen as the essence of blitzkrieg: concentrated panzer divisions performing swift deep penetrations. This strategy was not initially accepted by German High Command. Nevertheless, the final plans for the invasion of France in 1940 hinged on the element of a ''Schwerpunkt'' at Sedan, and was assigned to such forces. The great success of this operation led to blitzkrieg being integrated with strategic planning for the rest of the war. German tanks could carry with them enough fuel and supplies to go almost two hundred kilometers, and enough food to last three to nine days. This relative independence from supply lines proved effective, and allowed them to advance on critical targets much faster and without hesitation. Another factor was the ability of commanders to make strategic decisions in the field and without much consultation with their headquarters, the orders of which were often simply ignored. A prime example is Erwin Rommel's lead-from-the-front approach while commanding ''7.Panzer-Division'' which allowed him a flexible response to the battlefield situation, an instance of the ''

'' (reliance on subordinates to make their own decisions). The effect of German ''Panzer'' speed, mobility, and communication shocked the French, and ultimately were the deciding factors in the battle. It overcame their inferiority in armour and armament relative to the main French materiel such as the Char B1 ''bis''. The superior tactical and operational praxis, combined with an appropriate strategic implementation, enabled the Germans to defeat forces superior in armour (both quantitatively and qualitatively) in the battles of 1940, but just as Blitzkrieg became a deliberate military doctrine, in 1941, it ultimately failed on the eastern front, though initially attaining spectacular successes. Before the war,

This allowed the panzer division to become an independent combat force, in principle able to overcome the problems of attaining a breakthrough against entrenched enemy infantry, equipped with large numbers of antitank-guns, with the potential to completely halt tank assaults inflicting devastating losses to armoured units without infantry support. However, much of the AFV production was increasingly diverted away from the ''Panzertruppe''. The Artillery formed its own Sturmgeschütz units and infantry divisions were given their own

. Having studied the early German successes McNair came under the belief that U.S. forces would be faced with fast moving enemy forces who would seek to bypass, isolate and reduce U.S. forces in a replay of the Fall of France. To stem the flood of marauding panzers, fast moving powerfully armed tank destroyer battalions were created to be held back and used in the counter-attack. It was also calculated that U.S. interests would be better served by large numbers of reliable (''battle-worthiness'') medium tanks rather than a smaller number of unreliable heavy tanks. It was decided therefore to slow the production of the U.S. heavy tank designs such as the

constructionZaloga and inter-service feuds (the marine branch of the IJN favoured all-around protective armour) IJA tanks were lightly armoured. As with most armour during the 1930s, the main guns were small in calibre: 37 mm for their Type 95 light tanks and 47 mm for the Type 97 medium tank, but this was sometimes compensated by a high muzzle velocity. The IJA's use of tanks in China exemplifies its doctrine:

During the three-month-long war, Japanese armour had shown their weakness against Soviet tanks; and the resulting Japanese defeat prompted a series of complaints by the Imperial Army to incorporate improvements in future Japanese armour.

light tanks up until 1941, although these vehicles were five years ''newer'' than the 1935 built Type 95's, the IJA and U.S. light tanks were comparable to each other, and seemingly performed well for their respective forces during jungle combat operations; during their phase of World War II. As with all armour, maintenance was a continuous challenge; especially in tropical environments. When IJA and SNLF (Imperial marines) tanks did clash with the enemy they were quickly destroyed by concealed anti-tank guns or overwhelming numbers of hostile tanks. Japan was a naval power, and concentrated its production on warships, thus placing a low priority on armoured vehicle development, its tanks becoming quickly obsolete during the later years of the war. A number of designs that were equal to heavier foreign types were on the drawing board at the beginning of the war, but would only be built in small numbers towards the end, being placed in reserve, to be deployed for the defence of Japan itself.

The Republic of China's National Revolutionary Army's 200th Division was the country's only mechanised division during the war. The 200th used pre-war tanks acquired from Italy, Germany, and the Soviet Union.

This is an extreme example but exemplifies what has been fairly thoroughly documented since the Second World War: tanks and infantry work best by taking advantage of each other's strengths and combining to minimise the weaknesses.

Emergence of guided missiles

While attempts to defeat the tank were made before and during the Second World War, through the use of conventional high velocity anti-tank artillery, this proved increasingly difficult in the post-war period due to increased armour protection and mobility of tanks. In response, the Soviet Union, the country with the largest armoured fleet in the world, strove to incorporate some anti-tank capability into almost every infantry weapon. By the 1960s, Soviet defense scientists were designing portable

21st century

Tanks rarely work alone; the usual minimum unit size is a platoon (a platoon is the smallest U.S. Army/Marine unit led by an officer, and a component of a company or troop) of three to five tanks. The tanks of the platoon work together providing mutual support: two might advance while covered by the others then stop and provide cover for the remainder to move ahead. Normally, multiple platoons coordinate with mechanised infantry and use their mobility and firepower to penetrate weak points in enemy lines. This is where the powerful engines, tracks and turrets come into play. The ability to rotate the turret by a full 360° allows coordinated movement within and between platoons, while defending against attacks from multiple directions and engaging troops and vehicles without stopping or slowing down. When on the defensive, they wait in prepared positions or use any natural

") exposes only the top of its turret, with the gun and sensors, to the enemy, leaving the smallest possible target while allowing it to engage the enemy on the other side of the hill. Tanks are usually able to depress the main gun below the horizontal since modern kinetic energy (KE) rounds have nearly flat trajectories. Without this they would be unable to exploit such positions. However, upon cresting a hill, the tank may expose its thinly armoured underside to enemy weapons. The deposition of armour around a tank is not uniform; the front is typically better armoured than the sides or rear. Accordingly, normal practice is to keep the front towards the enemy at all times; the tank retreats by reversing instead of turning around. Driving backwards away from an enemy is even safer than driving forwards towards them since driving forwards over a bump can throw the front of the tank up in the air, exposing the thin armour of the underside and taking the gun off the target due to its limited angle of depression. The tracks, wheels and suspension of a tank are outside the armoured hull and are some of the most vulnerable spots. The easiest way to disable a tank (other than a direct hit in a vulnerable area with a full-power anti-tank weapon) is to target the tracks for a " mobility kill" (''m-kill''), or target all external visual aids with rubbery cohesive substances such as melted rubber or blackened high viscosity epoxy resins. Once a tank is disabled it is easier to destroy. This is why side-skirts are an important feature; they can deflect heavy machine-gun bullets and trigger the detonation of

s for increased protection. The tanks can fire off a few shots from their defensive position, then retreat (reversing) to another prepared position further back and drive behind the berms or into the trenches there. These positions can be constructed by the tank crews, but preparations are better and quicker if carried out by combat engineers with bulldozers. Overhead protection, even if it is fairly thin, can also be very useful since it can help pre-detonate artillery shells and avoid direct hits from above which can be deadly to tanks, by striking them at their thinnest armour. In short, tank crews find as many ways as possible to augment the armour on their vehicles. Tanks usually go into battle with a round in the gun, ready to fire, to minimise reaction time when encountering an enemy. The US doctrine calls for this round to be a kinetic energy (KE) round, as the reaction time is most important when meeting enemy tanks, to get the first shot (and possibly the first kill). If troops or light vehicles are encountered, the usual response is to fire this round at them, despite it not being ideal—it is difficult and time-consuming to remove a round which is already in the breech. In this case, after the KE round is fired, a HEAT round would normally be loaded next to continue the engagement. Tanks can be decisive in city fighting, with the ability to demolish walls and fire medium and heavy machine guns in several directions simultaneously. However, tanks are especially vulnerable in urban combat. It is much easier for enemy infantry to sneak up behind a tank or fire at its sides, where it is most vulnerable. In addition, firing down from multi-story buildings allows shots at the thin upper turret armour and even basic weapons like

s, if aimed at the engine air intakes, can disable a tank. Because of these limits, tanks are difficult to use in city conflicts where civilians or friendly forces might be nearby, since their firepower can't be used effectively.


Airborne threats

Tanks and other armoured vehicles are vulnerable to attack from the air for several reasons. One is that they are easily detectable—the metal they are made of shows up well on radar, and is especially obvious if they are moving in formation. A moving tank also produces a lot of heat, noise and dust. The heat makes seeing them on a forward-looking infra-red system easy and the dust is a good visual clue during the day. The other major reason is that most armoured vehicles have thinner armour on the roof of the turret and on the engine deck, so an anti-tank guided missile (from an attack helicopter or ground-attack jet) hitting them from the top can be deadly even if it has a small warhead. Even a small automatic cannon is powerful enough to penetrate the rear and top sections of the engine compartment of a tank. Certain aircraft have been developed to attack armoured vehicles. Most notable is the purpose-built Fairchild-Republic
A-10 Thunderbolt II The Fairchild Republic A-10 Thunderbolt II is a single-seat, twin-turbofan, straight-wing, subsonic attack aircraft developed by Fairchild Republic for the United States Air Force (USAF). In service since 1976, it is named for the Republic ...

Engineering support

Armoured warfare is mechanically and logistically intensive and requires extensive support mechanisms. Armoured fighting vehicles require ''armoured'' vehicles capable of working in the same terrain to support them. These are operated by the appropriate branches of the army, e.g. recovery and maintenance vehicles by the REME and combat engineering vehicles by the RE in the British Army. These include: *
Armoured recovery vehicle An armoured recovery vehicle (ARV) is typically a powerful tank or armoured personnel carrier (APC) chassis modified for use during combat for military vehicle recovery (towing) or repair of battle-damaged, stuck, and/or inoperable armoured f ...
s (ARV)—many of these are based on the chassis for the vehicle they support. E.g. the ARV for the UK Challenger tank is a Challenger hull onto which a winch is added. * Armoured supply vehicles * Combat engineering vehicles (CEV), e.g. bulldozers For transporting tracked AFVs over highways, heavy transporters are used, since AFVs are prone to malfunction and their tracks also ruin the highways.
