Introduction to Anti-Tank Weapons
Anti-tank weapons are specialized military tools designed specifically to incapacitate or destroy armored vehicles, such as tanks, that serve as critical components in modern warfare. The primary purpose of these weapons is to negate the advantages conferred by armor, enabling infantry and lighter vehicles to effectively counter one of the most formidable elements on the battlefield. The development of anti-tank technology became increasingly essential in the lead-up to World War II, reflecting significant advancements in both armored vehicle capabilities and battlefield tactics.
The origins of anti-tank weapons can be traced back to the advent of armored warfare during World War I, when the British introduced tanks to break the stalemate of trench warfare. As tanks became more common in military arsenals, the need for effective countermeasures became evident. Early approaches included employing a variety of improvised explosive devices and dedicated firepower, with notable developments occurring between the wars. Innovations such as the anti-tank rifle and grenade highlighted the military’s response to the growing effectiveness of armored vehicles, setting the stage for more sophisticated designs that would emerge in the 1930s.
As World War II approached, several nations recognized that traditional infantry weapons lacked the lethality required to penetrate the increasingly resilient armor of contemporary tanks. This prompted nations to accelerate their research and development in anti-tank technologies. Notably, this period saw the introduction of towed and self-propelled anti-tank guns, which provided greater firepower and mobility. Furthermore, guided missiles and shaped charges began to appear, offering new means to combat the armored threats on the battlefield. Understanding the evolution and utility of anti-tank weapons in this historical context is vital to appreciating the strategies employed by military forces throughout World War II.
Early Development of Anti-Tank Weapons
The period between the First and Second World Wars witnessed significant innovations in military technology, particularly in the design and development of anti-tank weapons. The need for effective solutions to counter the armored vehicles that would define modern warfare became increasingly apparent during this time. Early anti-tank weaponry designs laid the groundwork for more advanced systems used in World War II.
During the interwar years, various nations began experimenting with projectiles specifically designed to penetrate armor. One of the most notable innovations was the development of the armor-piercing shell, which utilized hardened steel or tungsten carbide cores to increase its ability to breach protective materials. These projectiles were initially designed to be fired from existing artillery pieces, enhancing their effectiveness without necessitating a complete overhaul of artillery systems. The advancements made during this period allowed militaries to refine the capabilities of traditional weapons to combat emerging threats posed by tanks.
Explosives also evolved significantly, contributing to the effectiveness of anti-tank tactics. The introduction of shaped charges during the late 1930s marked a significant leap in anti-tank technology. This design allowed for a concentrated explosion that could penetrate armor more efficiently than conventional explosives. The idea that a smaller charge could yield a more focused destructive power changed the landscape of anti-tank warfare, leading to the development of handheld models and larger, vehicle-mounted systems.
Technological advancements, such as the increasing reliability of explosives and improvements in projectile design, played a crucial role in the evolution of anti-tank weaponry. As militaries adapted to the growing prevalence of armored vehicles, the innovations made during this period established a foundation that would inform the strategies and technologies utilized in World War II. These early developments in anti-tank weapons were instrumental in shaping the future of ground warfare and addressing the challenges presented by enemy armor.

Major Anti-Tank Weapons Used by the Allies
During World War II, the Allied forces employed a variety of anti-tank weapons designed to counter the armored divisions of their adversaries.
British
During World War II, Britain fielded several innovative anti-tank weapons to counter increasingly heavy German armor, evolving from kinetic rifles to shaped-charge projectors and powerful towed guns.
The Boys anti-tank rifle, a bolt-action .55-inch (13.9 mm) weapon introduced in 1937, weighed 36 lb (16 kg), measured 5 ft 3 in (1.6 m) long, and fired a 930-grain (60 g) armor-piercing round at 2,470 ft/s (753 m/s), penetrating up to 23 mm of armor at 300 yards—effective against early Panzer I/II but obsolete by 1942.
Replacing it for infantry was the Projector, Infantry, Anti-Tank (PIAT) Mk I, a spigot-mortared launcher entering service in mid-1943; at 34 lb (15 kg) and 3 ft 3 in (1 m) long, it required a two-man crew, launched a 3 lb (1.4 kg) hollow-charge bomb via a 200 lb spring and tail cartridge to an effective anti-tank range of 100–115 yards (91–105 m), penetrating 100 mm (4 in) of armor with no back-blast or muzzle flash, and could lob high-explosive rounds indirectly to 350 yards for bunker-busting.
For divisional artillery, the Ordnance QF 2-pounder (40 mm, 1,850 lb towed) opened the war with a 2 lb AP shot at 2,600 ft/s penetrating 50 mm at 500 yards, but was outclassed by 1941. It gave way to the QF 6-pounder (57 mm, 2,500 lb, crew of 6) from 1942, firing a 6.3 lb APCBC round at 2,700–2,900 ft/s to defeat 80–90 mm at 500 yards (or 140 mm with rare APDS), remaining mobile and potent through 1945.
The pinnacle was the QF 17-pounder (76.2 mm, 6,600 lb towed, crew of 5–6), rushed into service in 1943; its 17 lb APCBC projectile reached 2,900 ft/s to pierce 140 mm at 1,000 yards, while APDS sabots hit 3,950 ft/s for 200+ mm penetration, arming towed platoons, Sherman Fireflies, Archers, and Achilles tank destroyers to reliably knock out Tigers and Panthers at long range.
USA
The Bazooka, officially designated as the M1 rocket launcher, was the primary American anti-tank weapon introduced in 1942 during World War II. This shoulder-fired, portable tube measured 54 inches in length, weighed approximately 13-15 pounds unloaded, and featured a smoothbore 2.36-inch (60mm) diameter steel barrel. It fired the fin-stabilized M6 or M6A1 high-explosive anti-tank (HEAT) rocket, propelled by a solid-fuel M1 rocket motor that achieved a muzzle velocity of about 265 feet per second and an effective range of up to 200 yards.
The shaped-charge warhead could penetrate up to 100mm (4 inches) of homogeneous armor at a 90-degree impact angle, making it capable of defeating German Panzers like the Panzer III and IV, as well as Japanese medium tanks. Operated by a two-man team (gunner and loader), the electrically fired, reusable launcher allowed rapid reloads and provided infantry with a lightweight, man-portable means to counter armored threats on the battlefield.
Soviet
During World War II, the Soviet Union relied heavily on two primary infantry-portable anti-tank rifles—the PTRD-41 (designed by Vasily Degtyaryov) and the PTRS-41 (designed by Sergei Simonov)—both chambered for the powerful 14.5×114mm cartridge and rushed into production in August 1941 to counter the German invasion.
The PTRD-41 was a single-shot, bolt-action weapon weighing 17.5 kg (38.5 lb) unloaded, measuring 2.02 m (79.5 in) long with a 1.23 m barrel, and fired a 64 g armor-piercing bullet at a muzzle velocity of 1,012 m/s (3,320 ft/s); it could penetrate 40 mm of rolled homogeneous armor at 100 m (or 30 mm at 500 m) when striking at a 90° angle, making it lethal against the side and rear armor of early Panzer IIIs and IVs (typically 30 mm thick). Its simple, robust design allowed rapid mass-production (over 280,000 units) and easy breakdown into two loads for transport.
The semi-automatic PTRS-41, by contrast, used gas-operated action with a tilting-bolt lock and fed from a 5-round en-bloc clip (inserted from below), weighing 20.9 kg (46 lb), stretching 2.11 m (83 in) overall with a 1.22 m barrel, and achieving a practical rate of 15 rounds per minute; it delivered identical ballistics and penetration but was more complex, prone to jamming when dirty, and produced in fewer numbers (about 190,000) due to manufacturing demands.
Both rifles were operated by two-man teams (gunner and loader/ammo bearer), featured offset iron sights, a large muzzle brake and shoulder pad to mitigate brutal recoil, and proved most effective at 300–500 m against lighter vehicles, tracks, vision slits, or thinly armored half-tracks, while later-war heavy German tanks (Panther, Tiger) forced their relegation to anti-materiel roles against trucks, bunkers, and low-flying aircraft. Supplementing these were shaped-charge hand grenades like the RPG-43 (1943), which offered 75 mm penetration via a thrown HEAT warhead.

Major Anti-Tank Weapons Used by the Axis Powers
The Axis powers, particularly Germany, developed and employed a variety of anti-tank weapons during World War II, which significantly influenced ground warfare tactics.
Germany
During World War II, Germany fielded a diverse array of anti-tank weapons to counter increasingly heavy Allied and Soviet armor, evolving from early anti-tank rifles to powerful towed guns and innovative shoulder-fired rocket systems.
The Panzerbüchse 39, a single-shot 7.92×94mm Patronen anti-tank rifle introduced in 1939, weighed 12.1 kg with a 1.085 m barrel, achieved a muzzle velocity of 1,265 m/s, and penetrated up to 30 mm of 60°-sloped armor at 100 m or 25 mm at 300 m—effective against light tanks but obsolete by 1941. The 7.5 cm PaK 40 towed anti-tank gun, developed by Rheinmetall, fired a 6.8 kg APCBC round at 792 m/s (or tungsten-cored AP40 at 933 m/s), and delivered devastating penetration: 132 mm at 500 m (30°) or 154 mm point-blank, defeating T-34s and Shermans at combat ranges up to 1,800 m with a 12–14 rounds/min rate of fire; over 23,000 were built.
For infantry, the disposable Panzerfaust series (1943–45) used a 44–50 mm launch tube (3–6.8 kg loaded) to propel a 1.5–3 kg shaped-charge warhead at 30–45 m/s over 30–100 m (depending on model: 30, 60, or 100), penetrating 140–200 mm of vertical armor—cheap, recoilless, and issued by the millions to Volkssturm and regular troops. The reusable Panzerschreck (RPzB 54), a direct scale-up of the captured U.S. Bazooka, featured a 1.64 m, 88 mm steel tube weighing 9.3 kg empty (11 kg loaded), electrically fired an RPzB.Gr. 4322 rocket at 110 m/s to 150–180 m, and its 3.3 kg hollow-charge warhead punched 210–230 mm of armor.
Japan
During World War II, the Imperial Japanese Army relied on a mix of towed anti-tank guns, semi-automatic rifles, and desperate close-assault weapons to counter Allied armor, as Japan faced few tanks early on and prioritized lighter, island-hopping warfare.
The Type 94 37mm anti-tank gun (1934) was the most common, weighing 324 kg combat-ready with a 1.67 m barrel, firing a 0.67 kg AP round at 700 m/s to penetrate 35 mm of armor at 500 m—effective against early light tanks like the M3 Stuart but useless against M4 Shermans. Its improved successor, the Type 1 37mm (1941), added a longer barrel for 800 m/s velocity and 40 mm penetration at 500 m, yet only 2,200 were built, and it remained marginal.
The breakthrough came with the indigenous Type 1 47mm anti-tank gun (1942), a low-silhouette 754 kg weapon on split-trail carriage with 60° traverse, hydro-spring recoil, and semi-automatic horizontal sliding breech; its 2.53 m barrel hurled a 1.4 kg APHE shell at 824 m/s, punching 70 mm at 500 m or 55 mm at 1,000 m—enough to defeat Sherman side armor beyond 1 km or frontal plates under 400 m. For infantry, the monstrous Type 97 20 mm automatic cannon (1939) weighed 52 kg empty (68 kg with shield), fed 7-round top magazines, and semi-automatically fired a 127 g AP round at 750 m/s to pierce 30 mm at 250 m or 20 mm at 700 m.
Late-war desperation birthed suicide tools: the Type 3 anti-tank grenade (a 1.2 kg burlap-wrapped HEAT cone penetrating 70 mm), hand-placed Type 99 magnetic mines (80 mm penetration), and the infamous lunge mine—a 6.5 kg, 2 m wooden pole with 3 kg conical HEAT charge penetrating 100–150 mm, thrust kamikaze-style into tracks or hulls. Shaped-charge rifle grenades and modified mountain-gun HEAT rounds rounded out the arsenal, but chronic shortages meant Japanese defenders often ambushed with field guns, Molotovs, or satchel charges in close jungle terrain.
Italy
During World War II, the Regio Esercito (Royal Italian Army) relied heavily on the Cannone da 47/32 Modello 1935—nicknamed Elefantino (“Little Elephant”)—as its primary anti-tank gun, a licensed copy of the Austrian Böhler 4.7 cm Infanteriegeschütz M.35 produced by Breda and Ansaldo. This compact, dual-purpose infantry-support/anti-tank piece weighed just 275 kg in action (with a 255 kg barrel), measured 1.68 m long (L/32 barrel), and was towed by light trucks or pack mules, making it highly mobile for mountain and desert divisions.
It fired a 1.48 kg AP round at 630 m/s (or 829 m/s in the rare L/40 variant), achieving 58 mm penetration at 500 m (30° impact) or 43 mm at 1,000 m; the Effetto Pronto (EP) HEAT shell boosted this to 70–80 mm at any range, while the German-supplied Granata a codolo (Stielgranate 41 copy) reached 90 mm. Effective range topped 500 m for tanks and 7 km for high-explosive fire, with a crew of 5–7 delivering 8–10 rpm via its semi-automatic sliding breech. Over 3,200 were built by 1943, arming every Italian division in North Africa, Russia, and Sicily.
Secondary options included the Swiss Solothurn S-18/1000 20 mm anti-tank rifle (12 kg, 870 m/s, 35 mm at 100 m, issued in small numbers for close-range ambushes) and captured French 25 mm Hotchkiss guns redesignated Cannone da 25/72 (L/72 barrel, 310 kg, 35 mm at 500 m). Late-war desperation saw the heavy Cannone da 90/53 AA gun pressed into anti-tank service, its 10 kg AP shell punching 140 mm at 500 m—enough for any Allied tank—but only 539 existed, mostly static or truck-mounted.
Despite excellent mobility and early-war parity with the British 2-pounder or German PaK 36, the 47/32’s light construction, lack of a shield, and obsolete AP performance against 1942–43 Matildas, Crusaders, and Shermans forced crews into suicidal close-range flank shots, highlighting Italy’s chronic shortfall in modern anti-tank weaponry.

Case Studies: Battles Highlighting Anti-Tank Weapon Effectiveness
The practical applications and strategic importance of anti-tank weapons during World War II are best understood through specific case studies. One of the most notable battles illustrating their effectiveness is the Battle of Kursk, fought in July and August of 1943. This encounter marked one of the largest tank battles in history and highlighted the significant role of anti-tank weaponry.
The Soviet forces, facing a formidable German offensive, heavily integrated anti-tank mines, artillery, and the infamous 76mm ZIS-3 guns. These weapons created a formidable defensive line, allowing Soviet troops to inflict substantial losses on German tanks, ultimately contributing to a decisive Soviet victory. The battle’s outcome demonstrated not just quantitative factors, such as the number of tanks, but also the qualitative effectiveness of anti-tank strategies deployed by the Red Army.
Another critical case study is the Battle of El Alamein, which took place in the North African campaign in late 1942. Here, British forces utilized a variety of anti-tank gun systems, including the 2-pounder and the more advanced 6-pounder, to counter the formidable Panzer divisions. The British forces employed defensive positions and combined arms tactics to leverage their anti-tank assets effectively. The use of anti-tank weapons was pivotal, enabling the Allied forces to halt the Axis advance, ultimately turning the tide of battle in favor of the Allies.
These case studies exemplify how anti-tank weapons not only facilitated tactical advantages in specific encounters but also influenced the broader strategic dynamics of World War II. By analyzing these battles, it becomes evident that the integration of anti-tank capabilities was essential in countering armored threats and securing territorial gains during the conflict.
Comparative Analysis of Allied vs. Axis Anti-Tank Strategies
The anti-tank strategies implemented by the Allied and Axis forces during World War II showcased distinct philosophies and methodologies aimed at countering armored threats. The Allies approached anti-tank warfare with a multifaceted strategy that emphasized flexibility and collaboration among different military branches.
This was characterized by the use of various weapon systems, including the British PIAT (Projector Infantry Anti-Tank), the American Bazooka, and the tank-mounted anti-tank guns. Each of these weapons was aimed at providing infantry units with effective means to engage enemy armor at varying ranges. Training for Allied troops often included close coordination with air support, enabling swift responses to armor movements.
In contrast, the Axis forces primarily relied on their technologically advanced tanks, such as the German Panzer series, to maintain offensive momentum. While they did develop dedicated anti-tank weapons, such as the Pak 40, their strategy heavily hinged on the application of armored units to outmaneuver and overpower the enemy. The German military placed significant emphasis on the use of combined arms tactics, integrating infantry, artillery, and tanks for a cohesive approach. This allowed them to execute rapid offensives, often leaving little time for enemy forces to organize effective countermeasures.
One notable difference between the two strategies was the emphasis on static versus mobile defense. The Allies generally favored a defensive approach when faced with significant tank assaults, relying on field fortifications and ambush tactics to exploit weaknesses in enemy formations. In contrast, the Axis forces maintained a more aggressive offensive posture, focusing on breaking through enemy lines rather than establishing a stationary defensive setup.
Final Say
Anti-tank weapons played a critical role in World War II, fundamentally altering the dynamics of ground combat. Their emergence was driven by the rapid advances in armored vehicles, which necessitated the development of specialized armaments capable of countering these formidable machines. In the war’s early years, traditional infantry tactics struggled against the onslaught of tanks, leading to significant losses. However, the introduction of effective anti-tank weaponry, such as the grenade launcher, anti-tank rifles, and later, more sophisticated systems like the bazooka and Panzerfaust, allowed infantry units to regain their competitive edge.
The strategic implications of anti-tank weapons cannot be understated. Their deployment influenced not only individual battles but also the broader operational strategies employed by various armies. The ability to halt or slow enemy armor formations enabled smaller, more mobile forces to contest larger ones effectively. Countries invested heavily in anti-tank technology, recognizing it as vital to their defensive and offensive capabilities. The experiences gained from the combat of this era served as critical lessons that shaped future military engagements.
Today, the legacy of World War II anti-tank weaponry remains pertinent. Modern warfare continues to see the adaptation and evolution of these concepts, reflecting the ongoing necessity of counteracting armored threats. As military technology advances, new forms of anti-tank systems—such as guided missiles and drones—have emerged, demonstrating the lasting influence of historical developments. The principles established during WWII still resonate within military strategies, ensuring that the importance of anti-tank capabilities endures in contemporary conflicts.
