Both sides in the Cold War also recognized the utility of the light anti-tank weapon, and this led to further development of man-portable weapons used by the infantry squad, while heavier missiles were mounted on dedicated missile tank-destroyers, including dedicated anti-tank helicopters, and even heavier guided anti-tank missiles launched from aircraft. Designers also developed new varieties of artillery munitions in the form of top-attack shells, and shells that were used to saturate areas with anti-armor bomblets. Helicopters could be used as well to rapidly deliver scattered anti-tank mines.

Tank threat

Anti-tank warfare evolved as a countermeasure to the threat of the tank's appearance on the battlefields of the Western Front of the First World War. The tank had been developed to negate the German system of trenches, and allow a return to maneuver against enemy's flanks and to attack the rear with cavalry. The use of the tank was mainly based on the assumption that, once they were able to eliminate the German trench lines with their machine gun and

positions, the Allied infantry would follow and secure the breach, and the cavalry would exploit the breach in the trench lines by attacking into the depth of German-held territory, eventually capturing the field artillery positions and interdicting logistics and reserves being brought up from the rear areas. Naval crews initially used to operate the installed naval guns and machine guns were replaced with Army personnel who were more aware of the

with which the tanks were intended to cooperate. However, there was no means of communication between the tank's crew and the accompanying infantry, or between the tanks participating in combat. Radios were not yet portable or robust enough to be mounted in a tank, although Morse Code transmitters were installed in some Mark IVs at Cambrai as messaging vehicles. Attaching a field telephone to the rear would become a practice only during the next war. With greater use of tanks by both sides it was realized that the accompanying infantry could be forced to ground by

. The French Army Staff was highly critical of the British Army's early fielding of the Mark I vehicles in small numbers because the French trials showed the armored vehicles to be highly unreliable. They judged that large numbers had to be employed to sustain an offensive despite losses to mechanical failure or vehicles being foundered in intractable no man's land terrain. These losses, coupled with those from enemy artillery fire, later amounted to as high as 70% of the starters during some operations. Deploying small numbers of tanks would therefore cause the Allies to lose the

Anti-tank weapons

Because the German Army was the only force in need of anti-tank weapons, they were first to develop a viable technology to combat the armored vehicle. These technologies took three ammunition approaches: use of grenades by infantrymen, including the ''Geballte Ladung'' ("Bundled Charge") of several stick grenades bound together by

Anti-tank tactics

With the appearance of Allied tanks, the German Army were quick to introduce new anti-tank defense detachments within the pioneer battalions of the infantry divisions. These were initially issued 13 mm caliber long barrel rifles firing solid shot. However, these suffered from fouling after 2–3 rounds and had a recoil that was unsustainable by the mechanism or the rifleman. Stick grenades were used to destroy the tracks by individual pioneers, however this required accompanying machine-gunners to first separate the supporting Allied infantry line from the tanks, which proved difficult. Another tactic was to lure the tank beyond the German trench-line, re-establishing it just as the Allied infantry approached. The tank would then be engaged by the divisional ''7.7 cm'' guns brought forward, that would try to disable the tracks with ordinary HE shells (and later AP ammunition). If the crews of the disabled tanks refused to surrender, they were engaged with flamethrowers, or a mortar would be fired on the stricken vehicle until a direct hit was achieved on the top surface, usually resulting in an internal fire. Finally, anti-tank obstacles were prepared on the likely approaches by deepening and widening existing ground cratering, the precursors of the
anti-tank trench Anti-tank trenches, also called anti-tank ditches, are ditches dug into and around fortified positions to hold up the advance of enemy tanks. Anti-tank ditches were first used in World War I by Germany in an effort to protect their trenches again ...
. Finally in early 1917 the ''3.7 cm TaK'' from Rheinmetall was rushed to the frontline, and proved effective in destroying the tanks despite limited elevation and traverse.


Development between the world wars

Lack of consensus on the design and use of the tank after the First World War also influenced the development of its anti-tank countermeasures. However, because Germany was restricted by the

. This came to influence their planning in 1940. The Maginot line defenses – up to deep from the forward positions to the rear line – were intended to prevent a surprise attack and delay any attack while the French Army was mobilized. With the relative numerical inferiority between the France and Germany, it was a more effective use of manpower. Within the line, passive anti-tank obstacles were supported by anti-infantry and anti-tank bunkers. After Belgium declared neutrality in 1936, France began work on extending the line along the Belgian border. Improved artillery was seen as the quickest solution to anti-tank defense, and one of the earliest post-war anti-tank gun designs was the 25 mm Hotchkiss model from France. It was intended to replace an Atelier de Puteaux 37 mm weapon designed in 1916 to destroy machine gun positions. Rheinmetall commenced design of a 37 mm anti-tank gun in 1924 and the first guns were produced in 1928 as 3.7 cm Pak L/45, later adopted in Wehrmacht service as 3.7 cm Pak 36.

ammunition was experimented with that used chemical energy for armor penetration. The shaped charge concept is officially known as the "Munroe Effect" and was discovered by accident decades earlier by Professor Charles E. Munroe at the U.S. Torpedo Station, Providence, RI. Professor Munroe was detonating different manufactured blocks of explosives on a sheet of armor plating and observed the blocks having the manufacturing letters recessed (vs. raised) cut an imprint of the manufacturing letters into the armor plate—the birth of the shaped-charged explosive which focuses the blast energy caused by an indentation on the surface area of an explosive. Although shaped charges are somewhat more difficult to manufacture, the advantage is that the projectile does not require as high velocity as typical kinetic energy shells, yet on impact it creates a high-

s to clear them on foot. Delay meant that Nationalist field artillery could engage the lightly armored Soviet tanks. This meant a change in Republican operational and eventually strategic planning, and a more protracted combat operations, with more casualties at a greater cost. The only change to the German anti-tank tactics of the First World War was that now an effective anti-tank weapon was available to support the defending infantry. However, the Soviet tanks armed with 45 mm guns easily destroyed the German light tanks. Ironically, in the early 1930s until the Spanish War, German officers were conducting secret testing of a new way of employing tanks, infantry and artillery offensively in the Soviet Union with the cooperation of the Red Army. In Germany, these developments eventually culminated in tactics that later came to be known as Blitzkrieg, while in the Soviet Union they formed the core of the

. The former regarded the tank as a mobile artillery system to be used for infantry support. This suggested that the infantry needed to be armed with integral anti-tank weapons. The latter advocated use of tanks in the traditional cavalry way of high-tempo attacks intended to outflank the enemy infantry and sever its communication lines. This approach suggested that the tank was the best anti-tank system, and only limited anti-tank troops were required to accompany them. For this reason the late 30s tank configurations came in a great diversity, ranging from light

s to multi-turreted heavy tanks resembling bunkers, all of which had to be considered in training by the anti-tank artillery troops. The development of these doctrines was the most significant influence on the rapid development in anti-tank technology and tactics in the Second World War.


Second World War

Two aspects of how the Second World War commenced helped to delay development of anti-tank warfare: resignation and surprise. After Poland was attacked, its allies in the West were resigned to its defeat by a numerically superior Wehrmacht. The little information that was brought out about the conduct of combat during that campaign did nothing to convince either France, Britain or the USSR of the need for improved anti-tank technology and tactics. The reliance on the Maginot Line, and the subsequent surprise of the German offensive left no time to develop existing abilities and tactics in the West. The British were preparing the stop lines and the anti-tank islands to slow enemy progress and restrict the route of an attack. The Red Army however was fortunate in having several excellent designs for anti-tank warfare that were either in final stages of development for production, or had been rejected earlier as unnecessary and could now be rushed into production. The relative ease with which the older models of Red Army's tank fleet were destroyed by German anti-tank weapons, using tactics already seen in Spain, once and for all focused Stavka attention on anti-tank warfare as Soviet armies were repeatedly encircled by panzer-led strategic pincer maneuvers. Of the major iconic Soviet weapons of the Second World War, two were made exclusively for anti-tank warfare, the

''Shturmovik''. The former was one of the most manufactured tanks in history, and the latter, itself dubbed the 'flying tank', was one of the most manufactured aircraft. The war also saw the creation and almost immediate abandonment of the self-propelled tank destroyer which would be replaced post war by the anti tank guided missile.


Aircraft

As tanks were rarely used in conflicts between the two World Wars, no specific aircraft or tactics were developed to combat them from the air. One solution adopted by almost all European air forces was to use bomb loads for conventional bombers that were composed from small bombs allowing a higher density during bombing. This created a greater chance of causing a direct impact on the thinner top armor of the tank while also having the ability to damage track and wheels through proximity detonation. The first aircraft able to engage tanks was the Junkers Ju 87 "Stuka" using

Field artillery

Field artillery were often the first ground combat arm to engage detected concentration of troops which included tanks through artillery airborne observers, either in assembly areas (for refueling and rearming), during approach marches to the combat zone, or as the tank unit was forming up for the attack. Conventional artillery shells were very effective against the tank's thinner top armor if fired in appropriate density while the tanks were concentrated, enabling direct hits by a sufficiently powerful shell. Even a non-penetrating shell could still disable a tank through dynamic shock, internal armor shattering or simply overturning the tank. More importantly the tanks could be disabled due to damage to tracks and wheels, and their supporting vehicles and personnel could be damaged and killed, reducing unit's ability to fight in the longer term. Because tanks were usually accompanied by infantry mounted on trucks or

Anti-tank guns

Anti-tank guns are guns designed to destroy armored vehicles from defensive positions. In order to penetrate vehicle armor, they fire smaller caliber shells from longer-barreled guns to achieve higher muzzle velocity than field artillery weapons, many of which are howitzers. The higher velocity, flatter trajectory ballistics provide terminal

The Red Army used a variety of 45 mm, 57 mm, and 100 mm guns, and deployed general-purpose 76.2 mm and 122-mm guns in the anti-tank role. By the time of the Invasion of Normandy, the British had the calibre QF 17 pounder, which design had begun before the 6 pounder entered service, in general use which proved to be a highly effective anti-tank gun and was also used on the Sherman Firefly tank, the Archer self-propelled gun, and on the 17-pdr SP Achilles


Tank destroyers

As towed anti-tank cannon guns grew in size and weight, they became less mobile and more cumbersome to maneuver, and required ever larger gun crews, who often had to wrestle the gun into position while under heavy artillery and/or tank fire. As the war progressed, this disadvantage often resulted in the loss or destruction of both the antitank gun and its trained crew. This gave impetus to the development of the self-propelled, lightly armored " tank destroyer" (TD). The tank destroyer was usually based on the hull of existing tank designs, using either a gun integrated into the hull or a fully rotating turret much like that of a conventional tank. These self-propelled (SP) AT guns were first employed as infantry support weapons in place of towed antitank guns. Later, due to a shortage of tanks, TDs sometimes replaced the former in offensive armored operations. Early German-designed tank destroyers, such as the
Marder I The ''Marder I'' "Marten" ( Sd.Kfz. 135) was a German World War II tank destroyer, armed with a 75 mm Pak-40 anti-tank gun. Most Marder Is were built on the base of the ''Tracteur Blindé'' 37L (Lorraine), a French artillery tractor/ar ...
, employed existing light French or Czech design tank chassis, installing an AT gun as part of an armored, turret-less superstructure. This method reduced both weight and conversion costs. The Soviet Union later adopted this style of self-propelled anti-tank gun or tank destroyer. This type of tank destroyer had the advantage of a reduced silhouette, allowing the crew to more frequently fire from

positions. Such designs were easier and faster to manufacture and offered good crew protection, though the lack of a turret limited the gun's traverse to a few degrees. This meant that, if the TD became immobilized due to engine failure or track damage, it could not rotate its gun to counter opposing tanks, making it an easy target. This vulnerability was later exploited by opposing tank forces. Late in the war, it was not unusual to find even the largest and most powerful tank destroyer abandoned on the field after a battle, having been immobilized by one high-explosive shell to the track or front drive sprocket. US Army pre-war infantry support doctrines emphasized the use of tank destroyers with open-top fully rotating turrets, featuring less armor than the standard

With rotating turrets and good combat maneuverability, American TD designs generally worked well, although their light armor was no match for enemy tank cannon fire during one on one confrontations. Another disadvantage proved to be the open, unprotected turret, and casualties from artillery fire soon led to the introduction of folding armor turret covers. Near the war's end, a change in official doctrine caused both the self-propelled tank destroyer and the towed antitank gun to fall from favor in U.S. service, increasingly replaced by conventional tanks or infantry level antitank weapons. Despite this change, the M36 tank destroyer continued in service, and was used in combat as late as the

These generally featured a heavy gun mounted on an older or then-current tank chassis, with the gun pointing forward with a limited degree of traverse. Casemate tank destroyers often had the same amount of armour as the tanks they were based on. The removal of the turret allowed for greater room to mount a larger gun with a larger breech and leave room for crew. Many casemate tank destroyers either originated as, or were dual-purpose vehicles with the duty of a self-propelled gun, which share many (but usually not all) of the same features and layout.

Rifles

Anti-tank rifles were introduced in some armies before the Second World War to provide infantry with a stand-off weapon when confronted with a tank assault. The intention was to preserve the morale of the infantry by providing a weapon that could actually defeat a tank.

By the beginning of WW2, anti-tank rifle teams could knock out most tanks from a distance of about 500 m, and do so with a weapon that was man-portable and easily concealed. Although the AT rifle performance was negated by the increased armor of medium and heavy tanks by 1942, they remained viable against lighter-armored and unarmored vehicles, and against field fortification embrasures.

s) the anti-tank rifle units helped to separate the supporting infantry ('' panzergrenadiers'') and artillery of the German tanks and so forced the tanks to halt at short distances from the concealed anti-tank guns leaving them exposed to fire from larger, longer ranged anti-tank guns. PTRS-41 semi-automatic anti-tank rifles were also used for sniping since an additional tracer round enabled rapid fire adjustment by the gunner. Although optical sniper scopes were tried with the PTRS-41, the weapons proved too inaccurate at sniping distances (800 m or more), and the recoil too much for effective use of the scopes.

) being very vulnerable to them, but later tanks required a well-thrown bottle directly over the engine compartment to have any effect at all. On the whole, thrown anti-tank weapons suffered from a variety of drawbacks. In addition to the inherently short range, they required careful aim to be effective, and those that relied on explosive force were often so powerful that the user had to take cover immediately. Additionally, with hand-thrown grenades, the requirement for the attacker to get close to the tank made the attacker exceptionally vulnerable to counter-attack from the tank (typically by machine gun), or from infantry -- mounted or dismounted troops -- accompanying the tank. However, if the attacker were very low to the ground, and in very close proximity to the tank -- for instance 30 feet (10 meters) or less -- it might be impossible for the tank crew to see the attacker."b.

Tactics

Anti-tank tactics developed rapidly during the war but along different paths in different armies based on the threats they faced and the technologies they were able to produce. Very little development took place in UK because weapons available in 1940 were judged adequate for engaging Italian and German tanks during most of the North African Campaign. Its experience therefore failed to influence the US Army's anti-tank doctrine prior to 1944. From 1941, German anti-tank tactics developed rapidly as a result of being surprised by the previously unknown Soviet tank designs, forcing introduction of new technologies and new tactics. The Red Army was also faced with a new challenge in anti-tank warfare after losing most of its tank fleet and a considerable part of its anti-tank capable cannons. Anti-tank tactics during the war were largely integrated with the offensive or defensive posture of the troops being supported, usually infantry. Most anti-tank tactics depend on the range effectiveness of various weapons and weapon systems available. These are divided as follows: *Operational range over the horizon (20–40 km range) *:Bomber aircraft and long range artillery *Tactical staging areas (7–20 km range) *:Ground attack aircraft and field artillery including MRLs *Tactical zone forming-up area and rear combat zone (2–7 km range) *:Heavy anti-tank guns and mortars *Tactical forward combat zone (1–2 km range) *:Anti-tank guns and tanks deployed in defense *Engagement distance (200–1000 m range) *:Mines and anti-tank rifles *Close combat distance (25–200 m range) *:Infantry anti-tank weapons Ground-to-air cooperation was not yet systematic in any army of the period, but given sufficient warning ground attack aircraft could support ground troops even during an enemy attack in an attempt to interdict the enemy units before they come into tactical combat zone. Various bomb loads can be used depending on what type of tank unit is engaged in at the time or who its accompanying troops are. This is an indirect form of anti-tank warfare where the tanks are denied the opportunity to even reach combat. Field artillery was particularly effective in firing against tank formations because although they were rarely able to destroy a tank by direct penetration, they would severely crater the area preventing the tanks from moving therefore causing them to become nearly stationary targets for the ground attack aircraft, or disrupting the enemy schedule and allowing own troops more time to prepare their defense. Anti-tank defense proper was by 1942 designed in First World War fashion with several prepared trench lines incorporating anti-tank weapons of different abilities. Depending on terrain and the available line-of-sight, the longer-ranged guns could begin to fire on approaching tanks from as far as 2 kilometers, which was also the range at which German Panther and Tiger tank gunners were trained to fire. Anti-tank guns were usually deployed to cover terrain more suitable for tanks, and were protected by minefields laid at about 500 meters to 1 kilometer from their positions by combat engineers. In the Red Army the anti-tank rifle units would be positioned throughout the forward trench line and would engage the lighter tanks and any other vehicles, such as infantry half-tracks in an attempt to separate them from the tanks. The anti-tank guns deployed further back would often hold their fire until enemy tanks were within the most effective range for their ammunition. Where there were insufficient anti-tank weapons, engineers would construct anti-tank obstacles such as dragon's teeth or

for example, the Red Army deployed more artillery regiments than infantry regiments and towed gun densities reached over 20 guns per kilometer of defended tactical zone. A towed gun was much cheaper than a tank and could be concealed in a shallow position. When time allowed, dugouts with strong overhead cover could be constructed. Guns deployed on reverse slopes and in flanking positions could take a toll of attacking tanks. However, gun crews were vulnerable to artillery, mortar HE fire and enemy infantry. Their positions had to be carefully selected and once engaged, they generally could not redeploy. Experience strongly suggested that towed AT guns were less effective than self-propelled AT weapons and took heavier casualties. The tactic of ambushing enemy armor at grazing shot distances was perfected during World War 2. Some combatants, like the Soviet Red Army, doctrinalized it and used it to engage heavy German armor at optimal distances and angles. Self-propelled anti-tank guns were rare at the beginning of WW2, although the

deployed a few T.15 tank destroyers and the French army was developing several wheeled and tracked designs. The advantages of mobility and even thin armor protection were so compelling that most armies were using self-propelled AT guns by mid-war. Examples of these weapons included the US M10, German

Infantry close assault

The tank is still vulnerable to infantry, especially in close country or built-up areas. Rough terrain may expose the floor armor, and high ground such as multi-story buildings may expose the top armor. Their large size and loud noise can allow enemy infantry to spot, track and evade tanks until an opportunity presents itself for counter-attack. Because tank crews have limited visibility from inside the tank, infantry can get close to a tank given enough concealment and if the hatches are closed. If tank crewmen unbutton for better visibility they become vulnerable to small arms fire, grenades and molotov cocktails. An infantryman cannot be targeted by a tank's main gun when close, as it cannot depress sufficiently. Close defense weapons such as pistol ports, hull-, coaxial- and pintle-mounted machine guns gave them some protection however. Whilst many hand-held infantry anti-tank weapons will not penetrate the front armor of a tank, they may penetrate the less heavily armored top, rear, and sides. Anti-tank weapons can damage the tracks or running gear to inflict a

s, hampering the crew. If all else fails, the hatch could also be forced open and grenades thrown inside, although later tank designs often have hatches designed to be difficult to open from the outside. Tanks were also vulnerable to hand-placed anti-tank mines. Infantry have even immobilized tanks using a set of plates covered with leaves and dirt as dummy mines – the ruse being augmented by the crew's obscured vision – infantry can then attack the stopped tank. This tactic was taught to the

during World War II since they were not often provided with long-range anti-tank weapons. In some cases in World War II, a tactic of some infantry was to run directly up to a tank, avoiding its main and machine guns, and pour petrol over and into the tank and light it, sometimes blocking the exit, burning the crew alive. In the Japanese army, the use of satchel charges and pole charges was widespread. Although the charges could knock out any allied tank, the tactic was extremely close-range and the sappers were vulnerable to allied weapons.

, the first specific attack helicopter that went into mass production was the Bell AH-1 Cobra in 1966. The AH-1 was equipped with BGM-71 TOW, TOW missiles in 1973 for anti-tank ability. The anti-tank helicopter armed with Anti-tank guided missile, ATGWs (Anti-Tank Guided Weapons) or anti-tank cannons is one of the biggest threats to a modern tank. The helicopter can position itself where it is not easily seen from a tank and then attack from any quarter, exposing the weaker parts of the tank's armor. The limited visibility from a closed-down tank also makes sighting a helicopter harder. Most helicopter-launched ATGWs have sufficient range that they can under the right conditions be fired at a range too long for the tank to retaliate with its own weapons. This may change with the Israelis fielding the 105mm and 120mm LAHAT missiles that can be fired from the main gun of the Merkava MBT. With both anti-tank and anti-helicopter role, it does level the playing field somewhat. The Indian Arjun (tank), Arjun tank has also been modified to fire this missile. The People's Republic of China has developed 100mm gun-launched missiles based on Russian designs such as the GP2 (based on the Russian 9M117 Bastion, Bastion). It has been reported to have successfully engaged aerial targets, and is an anti-tank missile. Similar missiles are available for Chinese tanks equipped with the 105 mm gun. The Russians have also displayed a similar if more advanced system in the 9M119 Svir, Reflex. The system involves an automatic targeting of an aerial/land target instigated by a laser warning system.


Artillery

In the last thirty years, however, a variety of artillery projectiles have been developed specifically to attack tanks. These include laser-guided projectiles, such as the US's Copperhead CLGP, Cannon Launched Guided Projectile (CLGP), which increases the chances of a direct hit. Some of these CLGPs (including the Copperhead) have HEAT warheads instead of common HE. Guided and unguided scatter munitions and submunitions have also been developed: one artillery shell containing several smaller munitions designed to attack a tank. A six-gun battery might be able to fire several hundred submunitions in a minute or two. In one form, a shell bursts in the air above one or more tanks and several

(HEAT) or high-explosive dual-purpose (HEDP) bomblets or grenades rain down. Any that hit a tank have a good chance to cause damage, since they are striking thin top armor. Another form scatters a number of small anti-tank mines in a tank's path, which probably will not penetrate the armor but can damage a track, leaving the tank mobility kill, immobile and vulnerable. More sophisticated are submunitions with a homing ability. Once again the shell explodes above the tank position and dispenses several submunitions. The munitions contain some circuitry to identify tanks, such as IR or millimeter radar. When a tank is identified, a rocket propellant is fired to shoot the projectile at the tank. These munitions will often descend by parachute, to allow time for target acquisition and attack. All of the above, but the CLGP can be fired from medium (105mm, 120mm, and 125mm) tank guns and medium (122mm, 130mm, 152mm, and 155mm) tube artillery. There has also been development of medium and large (81mm, 82mm, and 120mm) guided mortar munitions with both internal (e.g., IR or radar) or external (i.e., laser designator) guidance.


Missiles

The development of the wire-guided missile, or Anti-Tank Guided Weapon (ATGW) systems came into use in the late 1950s and 1960s that could defeat any known tank at ranges beyond that of the guns of the accompanying infantry. The United Kingdom, France, and other
NATO The North Atlantic Treaty Organization (NATO, ; french: Organisation du traité de l'Atlantique nord, ), also called the North Atlantic Alliance, is an intergovernmental military alliance between 30 member states – 28 European and two No ...
countries were among the first to develop such weapons (e.g., the Malkara missile by the United Kingdom and Australia in 1958). The Soviet Union, and now Russia, put extensive development into these weapons; the first man-portable model to enter service was the AT-3 Sagger, AT-3 in 1961. The United States was one of the last, coming up with the BGM-71 TOW in 1970. For a time, it appeared that the tank was a dead end. A small team of infantry with a few missiles in a well-concealed position could take on a number of the largest and most expensive tanks. In the 1973 Yom Kippur War, Soviet first-generation wire-guided missiles employed by the Egyptian forces inflicted heavy casualties on Israel Defense Forces, Israeli tank units, causing a major crisis of confidence for tank designers. Active protection systems, such as the Russian Arena active protection system, are starting to be more common, with similar systems such as the Israeli Iron Fist active protection system. The tank may be on a comeback because of active defense systems, which attack missiles in mid-air. This may allow the tank to be competitive on the battlefield once again.


Guns

Anti-tank guns continued to be used in a number of conflicts past World War 2 around the world, such as the Six-Day War and the South African Border War. Soviet anti-tank guns in particular were exported to at least eighteen other countries after being retired from service and have continued to see action. Rather than developing specialized anti-tank artillery, some nations, including South Africa and Israel, grafted obsolete tank guns onto towed carriages for use in that role.


Mines

Owing to greater sophistication of the tank, and engineering support available to tank units to detect and negate minefields, a considerable effort was made to develop more effective anti-tank mine technology in the effort to deny tank-led formations maneuver space, or channel their movement into unsuitable avenues of approach.


Infantry

The search for a more suitable, longer-range delivery system took up much of the immediate post-war era. The US invested in the recoilless rifle, delivering a widely used 75 mm design, and less common 90 mm and 106 mm designs (the latter was usually mounted rather than infantry-handled). The 106 mm formed the basis of a dedicated anti-tank vehicle, the Ontos tank, which mounted six 106 mm rifles. The Australian Army also fitted M40 recoilless rifles to Land Rover Series, Land Rover Series 2 vehicles for use in an anti-tank role. The Soviet Union also built recoilless rifles in various calibers intended to be used as anti-tank weapons, most commonly 73 mm, 82 mm, and 110 mm (only the 73 mm remains in service with the Russian military today, though the other two can be found all over the world due to Soviet military aid during the Cold War). The British used a 120 mm (4.7 inch) design to equip infantry units, the L6 Wombat, BAT series, which served from the 1950s until replaced by MILAN, but it was generally too heavy for infantry use and had to be towed by, or mounted on, a vehicle for maneuverability. The Soviet Union, Soviets developed the RPG-2 from the German ''Panzerfaust 150''. Further development led to the ubiquitous RPG-7. The RPG-7 is one of the most widely used anti-tank weapons, favored most by soldiers of Irregular military, irregular militaries. The RPG-7 could fire a range of different warheads, from thermobaric warheads to one HEAT or tandem-charge HEAT warheads against explosive reactive armor equipped tanks. The RPG-7 has a long combat history, and has been used in most wars from the Vietnam War all the way to present day wars. In modern times, the RPG-7 is generally used in an urban area, urban environment, which would enhance their effectiveness due to the close ranges involved. However, the aging RPG-7 has evolved to the even more potent

which has proven its worth in conflicts in the Middle East, damaging the Merkava IV, Challenger 2 and M1 Abrams main battle tanks. In the 1960s, the U.S. Army adopted the M72 LAW rocket, a lightweight, collapsible rocket launcher with the ability to penetrate moderate thicknesses of enemy armor. During the Vietnam War, the weapon was used primarily against NVA and Viet Cong defensive works and emplacements, as there were few encounters against enemy armor. Overall, the LAW was regarded as a success, though its ignition system frequently suffered from misfires in the heat and humidity of Vietnamese jungles. The LAW has since been replaced by the AT4 (M136).


Tactics

Changes in the anti-tank tactics since the Second World War mostly came from the appearance of new technologies, and increased firepower of the infantry mounted on fully armored vehicles. The most profound anti-tank technology has been the guided missile, which when coupled with a helicopter can mean that tanks can be engaged beyond ground line of sight (LOS), and at one of their most vulnerable aspect, the top armor.


Effectiveness

The effect of anti-tank warfare is to destroy or damage enemy tanks, or to prevent enemy tanks, and their supporting troops from maneuvering, which is the primary ability of a tank. In the US Army the degree of effect by an anti-tank weapon on a vehicle is referred to as either "

", "wiktionary:firepower kill, firepower kill", and "catastrophic kill". In a mobility kill (M-kill), the vehicle loses its ability to move, for example, by breaking a caterpillar track, tank track or bogey or damaging the engine; the targeted tank is then immobile, but may retain full use of its weapons (large cannon, heavy machine gun and smaller machine guns) and still be able to fight to some extent. However, a mobility-killed tank is a relatively vulnerable target to RPG or Molotov cocktail attacks, and it cannot maneuver to better firing positions. A firepower kill (F-kill) is some loss of the vehicle's ability to fire its weapons. For example, a tank may be hit on its main cannon, making the main gun inoperable. M-kills and F-kills may be complete or partial, the latter corresponding to reductions in a target's ability to move or fire. A catastrophic kill (K-kill) removes the tank's ability to fight completely; this may entail complete destruction of the tank or disabling or killing the crew.


Current trends

Although the future of the tank was questioned in the 1960s due to the development of the anti-tank missiles, increases in thickness and composition of armor, and other improvements in tank design meant that infantry operated systems were no longer sufficiently effective by the 1970s, and the introduction of Chobham armor by the British Army and
