Previous part : The War That Changed Everything: WWII Weapons Overview
In the autumn of 1944, a German soldier defending the Eastern Front carried a weapon that would have been entirely familiar to his father who fought in 1914 — a bolt-action Mauser rifle, manually cycled, five rounds in the magazine, capable of perhaps fifteen aimed shots per minute in trained hands. A few hundred meters away, a Soviet soldier advanced carrying a PPSh-41 submachine gun loaded with a 71-round drum magazine, capable of firing 900 rounds per minute. And somewhere behind the German lines, a small number of elite Waffen-SS troops were being issued a weapon that neither man would have recognized — the Sturmgewehr 44, the world's first assault rifle, which made both the bolt-action and the submachine gun simultaneously obsolete.
This was the peculiar character of WWII's infantry weapons revolution: three entire generations of small arms technology existed simultaneously on the same battlefields, in the hands of soldiers fighting within sight of each other. The bolt-action era, the submachine gun era, and the assault rifle era all overlapped within a single conflict — compressed into six years by the extraordinary pressure of total war.
This article examines the weapons that the ordinary WWII infantryman carried into battle — the rifles, submachine guns, machine guns, and pistols that defined ground combat from Poland 1939 to Berlin 1945. We will look at how they worked, how they compared against each other, and how the tactical lessons learned from their use in combat shaped every infantry weapon designed in the eight decades since.
The soldier's war. The weapons that were everywhere.
The State of Infantry Weapons in 1939
When the Second World War began in September 1939, the standard infantry rifle of every major power was a bolt-action weapon. The German Kar98k, the British Lee-Enfield No.4, the Soviet Mosin-Nagant M1891/30, the American Springfield M1903 — all operated on the same fundamental principle that had governed military rifle design since the 1880s: the soldier fires a round, manually works a bolt to eject the spent case and chamber a new round, and fires again. The theoretical maximum rate of aimed fire for a trained soldier was roughly fifteen rounds per minute. In practice, under stress, in cold weather, in mud — it was considerably less.
This was not ignorance or conservatism on the part of military planners. Bolt-action rifles had genuine advantages: they were accurate at long range, mechanically reliable in harsh conditions, and could be manufactured with the relatively modest industrial tooling available in the 1930s. The standard military doctrine of the era also held that aimed, individual fire at distance was more important than volume of fire — a doctrine shaped by WWI experience, where machine guns provided suppression and rifles provided precision.
But WWII combat, particularly in its Eastern Front urban battles and its Pacific jungle fighting, would rapidly expose the limitations of this doctrine. When German and Soviet soldiers were fighting room to room in the ruins of Stalingrad, or American Marines were clearing Japanese bunkers on Iwo Jima, the ability to deliver high volumes of fire at short range became overwhelmingly more important than long-range accuracy. The infantry weapons revolution of WWII was, at its core, a response to the brutal reality of close-quarters combat at industrial scale.
The Great Rifles: Bolt-Action vs Semi-Automatic
M1 Garand — America's War-Winner
The M1 Garand was the first standard-issue semi-automatic rifle adopted by any major military power, and its impact on American infantry combat was profound. Designed by Canadian-American engineer John Garand and adopted by the U.S. Army in 1936, it used a gas-operated mechanism to automatically cycle the action after each shot, allowing the soldier to fire again immediately without any manual bolt operation. Its eight-round en-bloc clip fed from below; when the last round was fired, the empty clip was automatically ejected with a distinctive metallic "ping" — a sound that became one of the iconic audio signatures of the American WWII experience. (Note: A popular myth holds that enemy soldiers could hear this "ping" and attack during the reload pause. Military historians including Ian McCollum have demonstrated this claim is largely unfounded — combat noise made the sound inaudible at any distance, and the Garand could be reloaded in under 3 seconds.)[1]
The practical combat advantage was stark. A trained American rifleman with an M1 Garand could deliver approximately 40–50 aimed rounds per minute. His German counterpart with a Kar98k could manage 15 at best. In a firefight at 200 meters between two equally skilled soldiers, the American had roughly three times the firepower. General George S. Patton famously called the M1 Garand "the greatest battle implement ever devised" — a judgment that, while characteristically hyperbolic, reflected a genuine tactical reality experienced by soldiers on both sides.[2]

Kar98k — Germany's Reliable Workhorse
The Karabiner 98 kurz — "short carbine 98" — was the standard rifle of the Wehrmacht throughout the entire war, and it was, by any objective measure, an excellent bolt-action weapon. Derived from the legendary Mauser Gewehr 98 of WWI fame, the Kar98k was shortened and lightened for easier infantry handling while retaining the parent design's exceptional accuracy and mechanical reliability. Its internal five-round magazine was loaded from stripper clips. Its 7.92×57mm Mauser cartridge had excellent ballistics at long range, and the rifle's action was among the smoothest and most dependable ever produced for a military bolt-action weapon.[3]
The Kar98k's weakness was not its design but its category. A bolt-action rifle, however well made, was a bolt-action rifle — and against an opponent with a semi-automatic weapon, the German infantryman was at a systematic disadvantage in the firefights that characterized WWII's most intense combat. German commanders were acutely aware of this problem by 1941, which is precisely why the development program that would eventually produce the StG44 was initiated with such urgency. The Kar98k was the rifle Germany fought the war with; the StG44 was the rifle Germany wished it had fought the war with.

Standard battlefield rate was typically lower. ** Mosin-Nagant M91/30: its stiff "sticky bolt" handle made cycling noticeably slower than the Kar98k or Lee-Enfield under field conditions.
The Submachine Gun War: Close-Range Dominance
If the bolt-action rifle represented the established order of infantry combat, the submachine gun represented its violent disruption. Firing pistol-caliber ammunition at high cyclic rates from detachable box or drum magazines, submachine guns sacrificed range and penetration for an overwhelming volume of fire at close quarters. In the rubble-filled streets of Stalingrad, the hedgerow-choked fields of Normandy, or the dense jungles of New Guinea, a submachine gun at 50 meters was worth far more than a bolt-action rifle at 500 meters.
Thompson M1928/M1 — The Chicago Typewriter
No WWII weapon carries a more loaded cultural history than the Thompson submachine gun. Designed by General John T. Thompson and commercially introduced in 1919, it had spent the interwar years in the hands of Prohibition-era gangsters before finding its way into military service. The early M1928 model, with its distinctive drum magazine and Cutts compensator, was heavy, expensive, and somewhat unwieldy. But its .45 ACP cartridge delivered devastating stopping power at close range, and the simplified M1 and M1A1 variants — stripped of the drum magazine option and the compensator, with a simpler fixed firing pin — proved to be robust, reliable combat weapons that American troops carried from the beaches of North Africa to the streets of Manila.[4]
MP40 — The Blitzkrieg's Voice
The MP40 — Maschinenpistole 40 — became one of the most visually iconic weapons of the entire war, synonymous in newsreels and photographs with the German soldier advancing across Europe in 1940 and 1941. Designed by Heinrich Vollmer and produced by Erma Werke, it was a sophisticated weapon for its era: its extensive use of stamped metal parts and plastics made it far cheaper and faster to produce than earlier SMG designs. Its folding metal stock made it compact enough for paratroopers and vehicle crews. Chambered for the 9mm Parabellum cartridge, it fired at 500–550 rounds per minute from a 32-round box magazine — controllable and accurate in short bursts.[5]
PPSh-41 — The Soviet Flood
The PPSh-41 — Pistolet-Pulemet Shpagina, or Shpagin Machine Pistol, 1941 — was perhaps the most important single infantry weapon of the Eastern Front. Designed by Georgi Shpagin and introduced in 1941 in direct response to the desperate early losses of Operation Barbarossa, it was a weapon designed first for producibility and second for everything else. Its stamped metal body, simple blowback mechanism, and chrome-lined barrel could be manufactured in small workshops with minimal tooling — over 6 million were produced during the war.[6] Its 71-round drum magazine gave a Soviet soldier nearly ten times the magazine capacity of a German soldier with a Kar98k, and its 900 rounds-per-minute cyclic rate produced a terrifying volume of fire in close-quarters combat. Soviet commanders would sometimes equip entire platoons exclusively with PPSh-41s for urban assault operations — a tactic that proved devastatingly effective in the fighting for Stalingrad and later Berlin.

Did You Know? — The Sten Gun's Radical Economics
The British Sten Mark II submachine gun — often derided for its crude appearance — cost approximately £2 10s to produce in 1941 (roughly £130 today). The Thompson, by comparison, cost $209 per unit for the early M1928 model — but through wartime simplification, the M1A1 variant's cost was reduced to approximately $45, demonstrating how production economics improved dramatically under wartime pressure. Britain produced over 2 million Stens during the war, supplying not only Commonwealth troops but also Resistance fighters across occupied Europe. The Sten's reputation was less for unreliability and more for being outright dangerous to its own user: its weak safety mechanism meant a dropped Sten could discharge on impact. Despite this, its near-zero production cost and the ability to manufacture copies in clandestine workshops made it one of the most strategically important weapons of the entire conflict.
The Machine Guns: Suppression as a Weapon
If the rifle was the queen of WWII infantry weapons, the machine gun was the instrument of terror. Machine guns did not win firefights by killing enemy soldiers directly — though they did that too. They won firefights by suppression: forcing enemy soldiers to keep their heads down, preventing accurate return fire, channeling movement into predictable paths where other weapons could engage. A well-positioned machine gun with adequate ammunition could pin down an entire infantry company almost indefinitely. The tactics of WWII infantry combat were, to a very large degree, the tactics of getting around, over, or through machine gun positions.
MG42 — Hitler's Buzzsaw
No infantry weapon of WWII inspired more fear among Allied soldiers than the MG42. Introduced in 1942 as a replacement for the earlier MG34, it was designed from the outset for mass production using stamped metal components and spot welding — a weapon built by industrial methods for industrial war. Its cyclic rate of fire was extraordinary: 1,200 to 1,500 rounds per minute, producing a distinctive ripping sound that Allied veterans consistently described as unlike any other weapon they had encountered. American training manuals specifically addressed the MG42's psychological impact, noting that its sound "causes involuntary reactions in soldiers" and advising commanders to prepare their men for it in advance.[7] This extreme rate of fire came with one critical tactical consequence: the barrel overheated severely after every 200–250 rounds. German MG42 crews trained intensively to swap barrels in under six seconds using an asbestos glove — a practiced drill that was itself a tactical skill, since a slow barrel change under fire could be fatal.
The MG42 was the definitive implementation of the General Purpose Machine Gun (GPMG) concept — a single weapon that could serve in the light machine gun role (bipod-mounted, carried with the infantry squad) or the heavy machine gun role (tripod-mounted with a sustained-fire mechanism for long-range defensive positions). This versatility meant that a single weapon design could equip the entire infantry fire support spectrum, dramatically simplifying German logistics. Its design was so successful that the postwar Bundeswehr adopted a modernized version — the MG3 — which remains in service with multiple militaries today.

| Total Produced | ~400,000 (1942–1945) |
Browning Automatic Rifle (BAR) — America's Squad Support
The Browning Automatic Rifle occupied an awkward tactical category — too heavy and too limited in magazine capacity (20 rounds) to function effectively as a light machine gun, too large and too automatic to be used comfortably as a rifle. Yet American infantry squads relied on it heavily as their primary automatic fire support, and BAR men — who were specifically targeted by enemy snipers and machine gunners — became among the most respected and most dangerous soldiers in any American unit. Its .30-06 cartridge was powerful and accurate to long range, and its 500-round-per-minute cyclic rate, while low by machine gun standards, was controllable enough for accurate fire in short bursts.[8]
Bren Light Machine Gun — Commonwealth Backbone
The Bren — derived from the Czech ZB vz. 26 and manufactured at the Royal Small Arms Factory in Enfield — was the standard light machine gun of Commonwealth forces throughout WWII, and it earned a reputation for exceptional accuracy and reliability in conditions ranging from the North African desert to the Burmese jungle. Its distinctive curved 30-round magazine fed from above; its relatively low cyclic rate of 500 rounds per minute made it more controllable and accurate in the sustained fire role than many faster-firing competitors. Commonwealth infantry sections were organized around the Bren as the central fire support element, with riflemen acting as protection and ammunition carriers for the gun team — a tactical doctrine that proved highly effective across multiple theaters.
The Revolution: Sturmgewehr 44 — Birth of the Assault Rifle
The Sturmgewehr 44 — "storm rifle," or "assault rifle," 44 — was the most consequential infantry weapons development of the Second World War, and arguably of the entire twentieth century. It did not win the war for Germany — it arrived too late, in too small numbers, and in the context of a military situation already beyond rescue. But it demonstrated, with devastating clarity, that the entire prior framework of infantry weapons design was obsolete. Every bolt-action rifle, every submachine gun, every traditional battle rifle became a transitional artifact the moment the StG44 appeared in meaningful numbers on the Eastern Front.
The fundamental insight behind the StG44 — developed by Hugo Schmeisser at C.G. Haenel — was statistical. German military analysts had studied thousands of infantry combat engagements and found that the overwhelming majority of firefights occurred at ranges under 300 meters. Standard rifle cartridges were designed for accuracy and penetration at 500–800 meters — ranges at which very little actual combat occurred. This meant that every soldier was carrying extra weight in propellant and bullet for capabilities he almost never used in practice.[9]
The solution was the intermediate cartridge: the 7.92×33mm Kurz ("short"), which was smaller and less powerful than the standard 7.92×57mm Mauser rifle round but far more powerful than a pistol cartridge. This intermediate-power round could be accurately fired on full-automatic at the ranges where combat actually happened, in a weapon light enough to be carried and used by a single infantryman. The result combined the range and accuracy advantage of the rifle with the volume-of-fire advantage of the submachine gun — and rendered both categories simultaneously obsolete.

Did You Know? — Hitler's Name Change
The StG44's development was deliberately disguised from Hitler, who had banned development of new rifle calibers in 1940 to simplify logistics. The weapon was initially designated "MP43" and "MP44" — Maschinenpistole, or "machine pistol" — to disguise it as a submachine gun variant and avoid Hitler's prohibition. When front-line commanders in the East reported overwhelming enthusiasm for the weapon, the reports finally reached Hitler directly. According to widely reported accounts, his response was enthusiastic: he reportedly asked why it had not been produced in larger numbers sooner, and personally approved the new designation "Sturmgewehr" — assault rifle — and the name has defined the weapon category ever since.[9]
Legacy: How These Weapons Changed the World
The infantry weapons of WWII did not merely influence postwar weapon design — they defined it. The categories established in that conflict, the tactical lessons learned at enormous human cost across its battlefields, and the technological concepts demonstrated under fire have shaped every infantry weapon developed in the eighty years since.
The assault rifle concept proven by the StG44 was adopted by every major military power within a decade of the war's end. The Soviet AK-47, introduced in 1947, used an intermediate cartridge (7.62×39mm) and selective-fire operation on the same principle — though its internal mechanism used a rotating bolt derived partly from the American M1 Garand, making the relationship to the StG44 more conceptual than mechanical.[10] The American M16, adopted in the 1960s, used an even smaller intermediate cartridge (5.56×45mm NATO). The British SA80, the French FAMAS, the German HK416, the Israeli Tavor — every infantry rifle in active service today is an assault rifle, every one of them a direct descendant of the concept that Hugo Schmeisser proved in the forests of the Eastern Front in 1943 and 1944.
The M1 Garand's semi-automatic principle also survived and spread. The American M14, the Soviet SVT-40's conceptual descendants, the modern designated marksman rifles that give infantry squads precision fire capability at ranges beyond the assault rifle's effective envelope — all reflect the lesson the M1 Garand taught in WWII: the semi-automatic mechanism is categorically superior to the bolt-action for general infantry use.
And the MG42's General Purpose Machine Gun concept became the universal standard for squad-level fire support. The American M60, the Belgian FN MAG, the German MG3, the British L7A2 — all are GPMGs in the tradition the MG42 established. Its 1,200-rounds-per-minute descendant, the MG3, is still in service with the German Bundeswehr and over thirty other militaries today.
The bolt-action rifle never returned as a general infantry weapon. The submachine gun survived in specialized roles — police work, close-protection, special operations — but was gradually displaced from mainstream infantry service by the assault rifle by the 1960s. The weapons that WWII's infantry carried into battle did not merely win that war; they wrote the blueprint for every infantry weapon that has been fielded since, and for every infantry tactic that has been practiced on every battlefield from Korea to Afghanistan.
