An anti-tank grenade is a specialized hand-thrown grenade used to defeat armored targets. Although their inherently short range limits the usefulness of grenades, troops can lie in ambush or maneuver under cover to exploit the limited outward visibility of the crew in a target vehicle. Hand launched anti-tank grenades became redundant with the introduction of standoff rocket propelled grenades and man-portable anti-tank systems.
Grenades were first used against armored vehicles during World War I, but it wasn't until World War II when more effective shaped charge anti-tank grenades were produced. AT grenades are unable to penetrate the armor of modern tanks, but may still damage lighter vehicles.
The first anti-tank grenades were improvised devices. During World War I the Germans were the first to come up with an improvised anti-tank grenade by taking their regular "potato masher" stick grenade and taping two or three more high explosive heads to create one larger grenade. In combat, after arming, the grenade was thrown on top of the slowly advancing tank where the armor was thin. The destructive properties of the stick grenade relied on its explosive payload, rather than the fragmentation effect, which was advantageous against hard targets.
During World War II, various nations made improvised anti-tank grenades by putting a number of defensive high explosive grenades into a sandbag. Due to their weight, these were normally thrown from very close range or directly placed in vulnerable spots onto an enemy vehicle. Another method used by the British Home Guard in 1940 was to place dynamite or some other high explosive in a thick sock and cover the lower part with axle grease and then place the grease covered part in a suitable size tin can. The sock was pulled out, the fuse lit and the sock thrown against the side of the tank turret in the hope it would stick until the explosion. If successful, it caused internal spalling of the armor plate, killing or injuring the tank crew inside. [1] It is unknown if this type of improvised anti-tank grenade was ever successfully employed in combat. By late 1940, the British had brought into production a purpose-built adhesive anti-tank grenade - known as the "sticky bomb" [2] - that was not very successful in combat. In Vietnam, the lunge mine was used in First Indochina War, specifically the Battle of Hanoi, during which Battalion Commander Nguyen Van Thieng tried to use it; however, "the bombs failed to explode. In the end, he was shot and heroically sacrificed". [3]
When tanks overran entrenchments, hand grenades could be, and were, used by infantry as improvised anti-tank mines by placing or throwing them in the path of a tank in the hope of disabling a track. While this method was used in desperation, it usually proved more dangerous to the soldier on the ground than to the crew of the tank.
Chinese troops in the Second Sino-Japanese War used suicide bombing against Japanese tanks. Chinese troops strapped explosives like grenade packs or dynamite to their bodies and threw themselves under Japanese tanks to blow them up. [4] This tactic was used during the Battle of Shanghai, where a Chinese suicide bomber stopped a Japanese tank column by exploding himself beneath the lead tank, [5] and at the Battle of Taierzhuang where dynamite and grenades were strapped on by Chinese troops who rushed at Japanese tanks and blew themselves up. [6] [7] [8] [9] [10] [11] During one incident at Taierzhuang, Chinese suicide bombers obliterated four Japanese tanks with grenade bundles. [12] [13]
Purpose-designed anti-tank grenades generally use the shaped charge principle to penetrate tank armor, although the high-explosive squash head (HESH) concept is also used. In military terminology, warheads employing shaped charges are called high-explosive anti-tank (HEAT) warheads. Because of the way shaped charges function, the grenade must hit the vehicle at an exact right angle for the effect to work most efficiently. The grenade design may ensure this by deploying a small drogue parachute or fabric streamers after being thrown, or improvised stabilisation fins if dropped from a drone.
Britain put the first purpose-built anti-tank grenade into the field during the Second World War in late 1940 with the No 68 AT Grenade, which was one of the first "any" type anti-tank weapons of the shape charge or HEAT type. The No 68 was fired from a rifle using the Mills grenade cup launcher. The Type 68 had a penetration of 50 mm (2.0 in) of armor plating, which was astonishing for 1940. Also developed by the UK during the war was the No 74 ST Grenade, popularly known as the "sticky bomb", in which the main charge was held in a glass sphere covered in adhesive. In anticipation of a German invasion, the British Army asked for ideas for a simple, easy to use, ready for production and cheap close-in antitank weapon. The ST Grenade was a government sponsored initiative, by MIR(c) , a group tasked with developing weapons for use in German and Italian occupied territory, and they placed the ST Grenade into mass production at Churchill's insistence, but seeing how it was operated, the British Army rejected it for the Home Guard much less their regular forces.
The No 74 Grenade was later issued to troops as an emergency stop-gap measure against lightly armored Italian tanks in North Africa, where it proved—to the surprise of many—highly effective. Later in the war, French partisans used the No 74 effectively in sabotage work against German installations. [14] The Hawkins grenade (No 75) was yet another anti-tank grenade that could be thrown or strung together in a chain and employed in a road-block.
Shortly after the German invasion of Russia in 1941, the Germans introduced the Panzerwurfmine(L), an extremely lethal close-quarter HEAT anti-tank grenade that could destroy the heaviest armored tanks in the war. The grenade was tossed overhand to land atop the tank. After release by the thrower, three spring-out canvas fins stabilized it during its short flight. The Panzerwurfmine(L) was lethal, and inexpensive to manufacture, but required considerable skill to throw accurately and was issued only to specially trained infantry tank-killer teams. [15]
It did not take long after the Russians captured the German Panzerwurfmine(L) to come out with their own hand-thrown anti-tank grenade with a HEAT warhead. In 1940, they developed a crude anti-tank grenade that used the simple blast effect of a large high explosive charge, designated RPG-40, which was stabilized in flight by a ribbon released after it was thrown. [16] The RPG-43 (developed in late 1943) was a modified RPG-40 with a cone liner and a large number of fabric ribbons for flight stabilization after release. In the last year of the war, they introduced the RPG-6, a total redesign of the RPG-43 with an improved kite-tail drogue in the handle and a standoff for the HEAT warhead, drastically increasing both accuracy and penetration, which was reported to be over 100 mm (3.9 in), more than adequate to cause catastrophic damage to any tank if it impacted the top. The Russian RPG-43 and RPG-6 were far simpler to use in combat than the German Panzerwurfmine(L) and did not require extensive training.
A special chapter of German anti-tank grenade is the "Geballte Ladung" (massed load). It is not a singular grenade model but some normal handgrenades which were linked to each other (multiple High Explosive loads in one stick grenade). Another such German attempt at man-portable AT weapons was the "Hafthohlladung" (attachable shaped charge). It was a large shaped charge equipped with three magnets so it would stick to a tank, but it was too heavy to be thrown: it had to be stuck to the target area of a tank directly.
After the end of World War Two, many eastern European nations engineered their own versions of the RPG-6, such as the Hungarian AZ-58-K-100. These were manufactured in the tens of thousands and given to 'armies of national liberation', seeing combat worldwide, including with the Egyptian Army during 1967 and 1973. [17] [18] [19]
The first Japanese anti-tank grenade was a hand-thrown grenade, which had a simple 100 mm (3.9 in) diameter cone HEAT warhead with a simple "all the way" fuse system in the base. (If dropped accidentally with the pin removed, it would explode). It had what looked like the end of a mop head on the tail end of the warhead. A soldier would remove the antitank grenade from its sack, pull the pin, and throw it gripping the mop-head as the handle. This was dangerous, as there was no arming safety after release and the thrower could strike something in his back swing before release. Penetration was reportedly only around 50 mm (2.0 in).
The second Japanese anti-tank grenade, a suicide weapon, was nicknamed the "lunge mine". [20] This weapon was a very large HEAT warhead on a five-foot stick. The soldier rammed it forward into the tank or other target, which broke a shear wire that allowed a strike pin to impact a primer and detonate the large HEAT warhead—destroying both soldier and target. [20] While crude, the Japanese lunge mine had six inches (150 mm) of penetration, the greatest penetration of any anti-tank grenades of World War Two.
The U.S. Army first encountered the hand-thrown anti-tank grenade in 1944, in the Philippines (some believe they were locally manufactured). The later suicide lunge mine first appeared during the U.S. invasion of Saipan and the subsequent invasion of Okinawa. Tens of thousands of these crude devices were produced and issued to both regular units and home-guard units on the home islands of Japan before the war ended. [21]

In the late 1970s, the U.S. Army was worried about the lack of emergency anti-tank weapons for issue to its rear area units, to counter isolated enemy armored vehicles infiltrating or being air dropped. When the US Army asked for ideas, engineers at U.S. Army laboratories suggested the reverse-engineered and additional safety improvements of the East German AZ-58-K-100 HEAT anti-tank grenade that had been clandestinely obtained. This concept was called "HAG" for "High-explosive Antiarmor Grenade". While the civilian engineers working for the US Army thought it was a great idea, it was rejected out of hand by almost all senior US Army officers with field experience, who thought it would be more dangerous to the troops who used them than the enemy. The idea was quietly shelved by 1985. [22] This decision left many rear-area U.S. units with no heavier "anti-tank weapon" than the M2 heavy machine gun.
The most widely distributed anti-tank grenades today are the post World War Two Russian designs of the 1950s and 1960s, mainly the RKG-3.
During the Iran–Iraq War, the 13 year old Iranian soldier Mohammad Hossein Fahmideh was celebrated as a war hero after he blew himself up under an Iraqi tank with a grenade.
Due to improvements in modern tank armor and the invention of rocket propelled grenades, anti-tank hand grenades are generally considered obsolete. However, in the recent Iraq War, the RKG-3 anti-tank hand grenade has made a reappearance with Iraqi insurgents who used them primarily against U.S. Humvees, Strykers and MRAPs, which lack the heavier armor of tanks. This has in turn led the U.S. to adopt countermeasures such as modifications to MRAP and Stryker vehicles by the fitting of slat armor, which causes the anti-tank grenade to detonate before coming in contact with the vehicle. [23]
The RKG-3 grenade has also be seen in use by the Aerorozvidka unit of the Ukrainian military in the 2022 Russian invasion of Ukraine. PJSC Mayak modifies the grenade [24] into the RKG 1600 by changing the fuze timing and adding 3D printed fins to stabilise its flight when dropped from a commercial drone. [25]
An (RPG) is named after the Russian letters: РПГ, meaning meaning "handheld anti-tank grenade launcher", the name given to early Russian designs. Most people think incorrectly Rocket Propelled Grenade. It is a shoulder-fired rocket weapon that launches rockets equipped with an explosive warhead. Most RPGs can be carried by an individual soldier, and are frequently used as anti-tank weapons. These warheads are affixed to a rocket motor which propels the RPG towards the target and they are stabilized in flight with fins. Some types of RPG are reloadable with new rocket-propelled grenades, while others are single-use. RPGs are generally loaded from the front.
A shaped charge is an explosive charge shaped to focus the effect of the explosive's energy. Different types of shaped charges are used for various purposes such as cutting and forming metal, initiating nuclear weapons, penetrating armor, or perforating wells in the oil and gas industry.
The Bazooka is a man-portable recoilless anti-tank rocket launcher weapon, widely deployed by the United States Army, especially during World War II. Also referred to as the "stovepipe", the innovative Bazooka was among the first generation of rocket-propelled anti-tank weapons used in infantry combat. Featuring a solid-propellant rocket for propulsion, it allowed for high-explosive anti-tank (HEAT) shaped charge warheads to be delivered against armored vehicles, machine gun nests, and fortified bunkers at ranges beyond that of a standard thrown grenade or mine. The universally applied nickname arose from the weapon's M1 variant's vague resemblance to the musical instrument called a bazooka invented and popularized by 1930s American comedian Bob Burns.
High-explosive anti-tank (HEAT) is the effect of a shaped charge explosive that uses the Munroe effect to penetrate heavy armor. The warhead functions by having an explosive charge collapse a metal liner inside the warhead into a high-velocity shaped charge jet; this is capable of penetrating armor steel to a depth of seven or more times the diameter of the charge. The shaped charge jet armor penetration effect is purely kinetic in nature; the round has no explosive or incendiary effect on the armor.
Anti-tank warfare originated during World War I from the desire to develop technology and tactics to destroy tanks. After the Allies deployed the first tanks in 1916, the German Empire introduced the first anti-tank weapons. The first developed anti-tank weapon was a scaled-up bolt-action rifle, the Mauser 1918 T-Gewehr, that fired a 13.2 mm cartridge with a solid bullet that could penetrate the thin armor used by tanks at that time and destroy the engine or ricochet inside, killing occupants. Because tanks represent an enemy's strong force projection on land, military strategists have incorporated anti-tank warfare into the doctrine of nearly every combat service since. The most predominant anti-tank weapons at the start of World War II in 1939 included the tank-mounted gun, anti-tank guns and anti-tank grenades used by the infantry, and ground-attack aircraft.
Panzerschreck was the popular name for the Raketenpanzerbüchse 54, an 88 mm reusable anti-tank rocket launcher developed by Nazi Germany in World War II. Another earlier, official name was Ofenrohr.
Stielhandgranate is the German term for "stick hand grenade" and generally refers to a prominent series of World War I and World War II–era German stick grenade designs, distinguished by their long wooden handles, pull cord arming and cylindrical warheads. The first models were introduced by the Imperial German Army during World War I and the final design was introduced during World War II by the German Wehrmacht.
The RPG-7 is a portable, reusable, unguided, shoulder-launched, anti-tank, rocket launcher. The RPG-7 and its predecessor, the RPG-2, were designed by the Soviet Union, and are now manufactured by the Russian company Bazalt. The weapon has the GRAU index 6G3.
An anti-tank or AT mine is a type of land mine designed to damage or destroy vehicles including tanks and armored fighting vehicles.
The RPG-27 is a Soviet single shot disposable rocket-propelled grenade (RPG) shoulder-fired missile and rocket launcher. It entered service with the Soviet Army in 1989.
Military vehicles are commonly armoured to withstand the impact of shrapnel, bullets, shells, rockets, and missiles, protecting the personnel inside from enemy fire. Such vehicles include armoured fighting vehicles like tanks, aircraft, and ships.
The Panzerfaust 3 is a modern semi-disposable recoilless anti-tank weapon, which was developed between 1978 and 1985 and first entered service with the Bundeswehr in 1987. It was first ordered in 1973 to provide West German infantry with an effective weapon against contemporary Soviet armor, thereby replacing West Germany's aging PzF 44 Light Lanze launchers and the heavy Carl Gustaf 84 mm anti-tank recoilless rifle manufactured in Sweden.
The RPG-2 is a man-portable, shoulder-fired anti-tank weapon that was designed in the Soviet Union. It was the first successful anti-tank weapon of its type, being a successor to the earlier and unsuccessful rocket-propelled grenade RPG-1.
RKG-3 is a series of Soviet anti-tank hand grenades. It superseded the RPG-43, RPG-40 and RPG-6 series, entering service in 1950. It was widely used in the 1973 Arab–Israeli War and remained a common weapon into the 2000s and early 2010s, being favoured by Iraqi insurgents during the American-led occupation. Modified versions of the RKG-3 series have also emerged in the Russian invasion of Ukraine.
Armour with two or more plates spaced a distance apart falls under the category of spaced armour. Spaced armour can be sloped or unsloped. When sloped, it reduces the penetrating power of bullets and solid shot, as after penetrating each plate projectiles tend to tumble, deflect, deform, or disintegrate; spaced armour that is not sloped is generally designed to provide protection from explosive projectiles, which detonate before reaching the primary armour. Spaced armour is used on military vehicles such as tanks and combat bulldozers. In a less common application, it is used in some spacecraft that use Whipple shields.
The RPG-43 was a high-explosive anti-tank (HEAT) shaped charge hand grenade used by the Soviet Union during World War II. It entered service in 1943, replacing the RPG-40; the RPG-40 used a simpler high explosive (HE) warhead. The RPG-43 had a penetration of around 75 millimetres (3.0 in) of rolled homogeneous armour at a 90° angle. Later in the war, it was improved and became the RPG-6.
The RPG-6 was a Soviet-era anti-tank hand grenade used during the late World War II and early Cold War period. It was superseded by the RKG-3 anti-tank grenade.
The RPG-40 was an anti-tank hand grenade developed by the Soviet Union in 1940. A marginally effective design capable of penetrating about 20–25 millimetres (0.79–0.98 in) of steel armour, it was soon replaced by the RPG-43 and later the RPG-6, both used shaped charges to increase penetration.
Beyond-armour effect is a term coined by Försvarets Fabriksverk (FFV), a semi-governmental Swedish defense firm, while developing the AT4 anti-tank weapon. From the 1980s, this phrase was used in its brochures, press releases, weapon instruction manuals and other documentation to denote the post-penetration effect of the AT4's HEAT anti-armour warhead against the interior and occupants of armoured vehicles.
Man-portable anti-tank systems are traditionally portable shoulder-launched projectile systems firing heavy shell-type projectiles, typically designed to combat protected targets, such as armoured vehicles, field fortifications and at times even low-flying aircraft.
