Origin of term
The term ''assault rifle'' is generally attributed to
Adolf Hitler
Adolf Hitler (20 April 1889 – 30 April 1945) was an Austrian-born German politician who was the dictator of Nazi Germany from 1933 until Death of Adolf Hitler, his suicide in 1945. Adolf Hitler's rise to power, He rose to power as the lea ...
, who used the German word ''Sturmgewehr'' (which translates to "assault rifle") as the new name for the MP 43 (''
Maschinenpistole)'', subsequently known as the
Sturmgewehr 44.
Allied propaganda suggested that the name was chosen for propaganda purposes, but the main purpose was to differentiate the Sturmgewehr from German submachine guns such as the
MP 40.
It has been suggested, however, that the ''
Heereswaffenamt'' was responsible for the name ''Sturmgewehr'', and Hitler had no input besides signing the
production order.
Furthermore, Hitler was initially opposed to the idea of a new infantry rifle, as Germany lacked the industrial capacity to replace the 12,000,000
Karabiner 98k rifles already in service, only changing his mind once he saw it first-hand.
The StG 44 is generally considered the first selective fire military rifle to popularize the assault rifle concept.
Today, the term ''assault rifle'' is used to define firearms sharing the same basic characteristics as the StG 44.
Definition
The
U.S. Army defines ''assault rifles'' as "short, compact, selective-fire weapons that fire a cartridge intermediate in power between submachine gun and rifle cartridges." In this strict definition, a firearm must have at least the following characteristics to be considered an assault rifle:
* It must be capable of
selective fire.
* It must have an
intermediate-power cartridge: more power than a
pistol but less than a standard
rifle
A rifle is a long gun, long-barreled firearm designed for accurate shooting and higher stopping power, with a gun barrel, barrel that has a helical or spiralling pattern of grooves (rifling) cut into the bore wall. In keeping with their focus o ...

* It must have an effective range of at least .
Rifles that meet most of these criteria, but not all, are not ''assault rifles'' according to the U.S. Army's definition. For example:

,
M14, and
H&K G3 main battle rifles are not assault rifles; they fire full-powered rifle cartridges.
* Semi-automatic-only rifles like the
Colt AR-15 are not assault rifles; they do not have select-fire capabilities.
* Semi-automatic-only rifles with fixed magazines like the
SKS are not assault rifles; they do not have detachable box magazines and are not capable of automatic fire.
Distinction from assault weapons
In the United States, selective-fire rifles are legally defined as "
machine guns", and civilian ownership of those has been tightly regulated since 1934 under the
National Firearms Act and since 1986 under the
Firearm Owners Protection Act.
However, the term "assault rifle" is often conflated with "
assault weapon", a U.S. legal category with varying definitions which includes many semi-automatic weapons. This use has been described as incorrect and a misapplication of the term.

Sturmgewehr 44

The Germans were the first to pioneer the assault rifle concept during World War II, based upon research that showed that most firefights happen within and that contemporary rifles were overpowered for most small arms combat.
[''Jane's Guns Recognition Guide'', Ian Hogg & Terry Gander, HarperCollins Publisher, 2005, p. 287 Sturmgewehr 44 "This is the father of all assault rifles, developed in Germany in 1941–42 a using a new short cartridge. Originally known as the MP 43 (Machine Pistol) for Nazi political reasons, it was renamed the "Sturmgewehr 44" after its successful introduction into battle on the Eastern Front. It introduced the concept of using a short cartridge with limited range in order to permit controllable automatic fire and a compact weapon, and because experience showed that most rifle fire was conducted at ranges under . After the war, it was examined and dissected by almost every major gun-making nation and led, in one way and another, to the present-day 5.56mm assault rifles."]

The result was the Sturmgewehr 44, an improvement of the earlier
Maschinenkarabiner 42(H), and approximately half a million Sturmgewehrs were produced by the war's end.
It fired a new and revolutionary intermediate powered cartridge, the 7.92×33mm Kurz.
M16 Rifle Case Study. Prepared for the President's Blue Ribbon Defense Panel. March 16, 1970. By Richard R. Hallock, Colonel U.S. Army (Retired) This new cartridge was developed by shortening the standard
7.92×57mm Mauser round and giving it a lighter 125-grain bullet, which limited range but allowed for more controllable automatic fire.
A smaller, lighter cartridge also allowed soldiers to carry more ammunition "to support the higher consumption rate of automatic fire".
The Sturmgewehr 44 features an inexpensive, easy-to-make, stamped steel design and a 30-round detachable box magazine. This weapon was the prototype of all successful automatic rifles. Characteristically (and unlike previous rifles) it had a straight stock with the barrel under the gas cylinder to reduce the turning moment of recoil of the rifle in the shoulder and thus help reduce the tendency of shots to climb in automatic fire. The barrel and overall length were shorter than a traditional rifle and it had a
pistol grip to hold the weapon more securely in automatic fire. "The principle of this weapon—the reduction of muzzle impulse to get usable automatic fire within the actual ranges of combat—was probably the most important advance in small arms since the invention of
smokeless powder."
AK-47

Like the Germans, the Soviets were influenced by experience showing that most combat engagements occur within and that their soldiers were consistently outgunned by heavily armed German troops, especially those armed with Sturmgewehr 44 assault rifles.

M16 Rifle Case Study. Prepared for the President's Blue Ribbon Defense Panel. March 16, 1970. By Richard R. Hallock, Colonel U.S. Army (Retired) "Used in quantity against the Soviets at Stalingrad, the German Sturmgewehr made a deep impression on the Russians. They copied the ballistics of the cartridge while improving the configuration and improving the weapon. They standardized the weapon in 1947 as the AK-47 rifle." On July 15, 1943, a Sturmgewehr was demonstrated before the
People's Commissariat of Arms of the USSR.
"The history of the world-known gun started on July 15th, 1943, when a captured complex—an MP-43 gun and a cartridge—were demonstrated at a meeting of the arms committee. Chief designer Nikolay Elizarov and chief engineer Pavel Ryazanov created the Soviet "interim cartridge " within a very short period of time. The technological support was provided by Boris Syomin.

[ Small Arms Identification and Operations Guide-Eurasain Communist Countries. by Harold E. Johnson. September 1973. U.S. Army Foreign Science and Technology Center of the U.S. Army Materiel Command.] Hugo Schmeisser, the designer of the Sturmgewehr, was captured after World War II, and, likely, helped develop the AK-47 assault rifle,
which would quickly replace the SKS and Mosin in Soviet service. The AK-47 was finalized, adopted and entered widespread service in the Soviet army in the early 1950s.
Its firepower, ease of use, low production costs, and reliability were perfectly suited for the Red Army's new
mobile warfare doctrines.
In the 1960s, the Soviets introduced the
RPK light machine gun, itself an AK-47 type weapon with a
bipod, a stronger receiver, and a longer, heavier barrel that would eventually replace the RPD light machine gun.

The AK-47 was widely supplied or sold to nations allied with the USSR, and the blueprints were shared with several friendly nations (the

standing out among these with the

As a result, more AK-type weapons have been produced than all other assault rifles combined.
As of 2004, "of the estimated 500 million firearms worldwide, approximately 100 million belong to the Kalashnikov family, three-quarters of which are AK-47s."
Post-StG battle rifles

The U.S. Army was influenced by combat experience with semi-automatic weapons such as the
M1 Garand
The M1 Garand or M1 rifleOfficially designated as U.S. rifle, caliber .30, M1, later simply called Rifle, Caliber .30, M1, also called US Rifle, Cal. .30, M1 is a semi-automatic rifle that was the service rifle of the United States Army, U.S. ...
and
M1 Carbine, which enjoyed a significant advantage over enemies armed primarily with bolt-action rifles.
Although U.S. Army studies of World War II combat accounts had very similar results to that of the Germans and Soviets, the U.S. Army failed to recognize the importance of the assault rifle concept,
and instead maintained its traditional views and preference for high-powered semi-automatic rifles.
At the time, the U.S. Army believed that the Sturmgewehr 44 was "intended in a general way to serve the same purpose as the U.S. carbine" and was in many ways inferior to the M1 carbine, and was of "little importance".
After World War II, the United States military started looking for a single automatic rifle to replace the M1 Garand, M1/M2 Carbines,
M1918 Browning Automatic Rifle,
M3 "Grease Gun" and
Thompson submachine gun.
Early experiments with select-fire versions of the M1 Garand proved disappointing. During the
Korean War
The Korean War (25 June 1950 – 27 July 1953) was an armed conflict on the Korean Peninsula fought between North Korea (Democratic People's Republic of Korea; DPRK) and South Korea (Republic of Korea; ROK) and their allies. North Korea was s ...
, the select-fire M2 Carbine largely replaced the submachine gun in U.S. service
and became the most widely used Carbine variant. Combat experience suggested that the
.30 Carbine round was under-powered. American weapons designers reached the same conclusion as the German and Soviet ones: an intermediate round was necessary, and recommended a small-caliber, high-velocity cartridge.
Senior American commanders had faced fanatical enemies and experienced major logistical problems during World War II and the Korean War, and insisted that a single powerful .30 caliber cartridge be developed, that could be used by the new automatic rifle, and also by the new
general-purpose machine gun (GPMG) in concurrent development.

The Heckler & Koch G3 is a 7.62×51mm, selective fire, automatic rifle produced by the German armament manufacturer
Heckler & Koch GmbH (H&K) in collaboration with the Spanish state-owned design and development agency
CETME (''Centro de Estudios Técnicos de Materiales Especiales''). The rifle proved successful in the export market, being adopted by the armed forces of over 60 countries. After World War II, German technicians involved in developing the
Sturmgewehr 45, continued their research in France at CEAM. The StG 45 mechanism was modified by Ludwig Vorgrimler and Theodor Löffler at the Mulhouse facility between 1946 and 1949. Vorgrimler later went to work at CETME in Spain and developed the line of CETME automatic rifles based on his improved StG 45 design. Germany eventually purchased the license for the CETME design and manufactured the Heckler & Koch G3 as well as an entire line of weapons built on the same system, one of the most famous being the
MP5 SMG.
M16
The first confrontations between the AK-47 and the M14 ("assault rifle" vs "battle rifle") came in the early part of the
Vietnam War
The Vietnam War (1 November 1955 – 30 April 1975) was an armed conflict in Vietnam, Laos, and Cambodia fought between North Vietnam (Democratic Republic of Vietnam) and South Vietnam (Republic of Vietnam) and their allies. North Vietnam w ...
. Battlefield reports indicated that the M14 was uncontrollable in full-auto and that soldiers could not carry enough ammunition to maintain fire superiority over the AK-47.
And, while the M2 Carbine offered a high rate of fire, it was under-powered and ultimately outclassed by the AK-47. A replacement was needed: A medium between the traditional preference for high-powered rifles such as the M14, and the lightweight firepower of the M2 Carbine.
As a result, the Army was forced to reconsider a 1957 request by General Willard G. Wyman, commander of the U.S. Continental Army Command (CONARC) to develop a .223 caliber (5.56 mm) select-fire rifle weighing when loaded with a 20-round magazine.
The 5.56 mm round had to penetrate a standard U.S.
helmet at and retain a velocity in excess of the speed of sound, while matching or exceeding the wounding ability of the .30 Carbine cartridge.
This request ultimately resulted in the development of a scaled-down version of the
ArmaLite AR-10, called the
ArmaLite AR-15 rifle.

concluded that the AR-15 was the superior weapon system and ordered a halt to M14 production.
At the time, the AR-15 was the only rifle available that could fulfill the requirement of a universal infantry weapon for issue to all services.
After modifications (most notably, the charging handle was re-located from under the carrying handle like it was on AR-10 to the rear of the receiver),
the newly redesigned rifle was subsequently adopted as the M16 Rifle.
[Report of the M16 rifle review panel](_blank)
. Department of the Army. dtic.mil. 1 June 1968 "(The M16) was much lighter compared to the M14 it replaced, ultimately allowing soldiers to carry more ammunition. The air-cooled, gas-operated, magazine-fed assault rifle was made of steel, aluminum alloy and composite plastics, truly cutting-edge for the time. Designed with full and semi-automatic capabilities, the weapon initially did not respond well to wet and dirty conditions, sometimes even jamming in combat. After a few minor modifications, the weapon gained in popularity among troops on the battlefield."
Despite its early failures, the M16 proved to be a revolutionary design and stands as the longest continuously serving rifle in American military history.
It has been adopted by many U.S. allies and the 5.56×45mm NATO cartridge has become not only the NATO standard but "the standard assault-rifle cartridge in much of the world".
[Per G. Arvidsso]

. NATO Army Armaments Group It also led to the development of small-caliber high-velocity service rifles by every major army in the world, including the USSR and People's Republic of China.

HK33
During the 1960s other countries would follow the Americans' lead and begin to develop 5.56×45mm assault rifles, most notably Germany with the
Heckler & Koch HK33. The HK33 was essentially a smaller 5.56mm version of the 7.62×51mm Heckler & Koch G3 rifle. As one of the first 5.56mm assault rifles on the market, it would go on to become one of the most widely distributed assault rifles. The HK33 featured a modular design with a wide range of accessories (telescoping butt-stocks, optics, bi-pods, etc.) that could be easily removed and arranged in a variety of configurations.
5.56mm NATO

The adoption of the M16, the H&K33, and the 5.56×45mm cartridge inspired an international trend towards relatively small-sized, lightweight, high-velocity military service cartridges that allow a soldier to carry more ammunition for the same weight compared to the larger and heavier 7.62×51mm NATO cartridge. The 5.56mm cartridge is also much easier to shoot.
[Assault Rifles and Their Ammunition: History and Prospects by Anthony G. Williams](_blank)
In 1961 marksmanship testing, the U.S. Army found that 43% of AR-15 shooters achieved Expert, while only 22% of M-14 rifle shooters did so. Also, a lower
recoil impulse, allows for more controllable automatic weapons fire.
In March 1970, the U.S. recommended that all NATO forces adopt the 5.56×45mm cartridge.
This shift represented a change in the philosophy of the military's long-held position about caliber size. By the middle of the 1970s, other armies were looking at assault rifle-type weapons. A NATO standardization effort soon started and tests of various rounds were carried out starting in 1977.
The U.S. offered the 5.56×45mm M193 round, but there were concerns about its penetration in the face of the wider introduction of
body armor.
In the end the Belgian 5.56×45mm SS109 round was chosen (
STANAG 4172) in October 1980.
The SS109 round was based on the U.S. cartridge but included a new stronger, heavier, 62-grain bullet design, with better long-range performance and improved penetration (specifically, to consistently penetrate the side of a steel helmet at ).
Also during the 1970s, Finland, Israel, and South Africa introduced AK type assault rifles in 5.56×45mm. Sweden began the transition with trails in 1981 and full adaptation in 1986. During the 1990s, Russia developed the
AK-101 in 5.56×45mm NATO for the world export market.

AK-74

The AK-74 assault rifle was a Soviet answer to the U.S. M16.
The Soviet military realized that the M16 had better range and accuracy over the AKM, and that its lighter cartridge allowed soldiers to carry more ammunition. Therefore, in 1967, the USSR issued an official requirement to replace the AKM and the 7.62×39mm cartridge.
They soon began to develop the AK-74 and the
5.45×39mm cartridge.
AK-74 production began in 1974,
and it was unveiled in 1977, when it was carried by Soviet
parachute troops during the annual
Red Square parade.
[''Military Small Arms Of The 20th Century'', 7th Edition, 2000 by Ian V. Hogg & John S. Weeks, p. 271] It would soon replace the AKM and become the standard Soviet infantry rifle.
In 1979, the AK-74 saw combat for the first time in

, where the lethality of the 5.45mm rounds led to the
Mujahadeen dubbing them "poison bullets".
The adoption of the 5.56mm NATO and the Russian 5.45×39mm cartridges cemented the worldwide trend toward small caliber, high-velocity cartridges.
Compact assault rifles

Following the adoption of the M16, carbine variants were also adopted for close quarters operations. The AR-15 family of weapons served through the Vietnam War. However, these compact assault rifles had design issues, as "the barrel length was halved" to which "upset the ballistics", reducing its range and accuracy and leading "to considerable muzzle flash and blast, so that a large flash suppressor had to be fitted".

Other compact assault rifles, such as the HK53, AK-74#AKS-74U, AKS-74U and the Daewoo K1, have been made and they have also been called submachine guns.
Bullpups

In 1977, Austria introduced the 5.56×45mm
Steyr AUG bullpup rifle, often cited as the first successful
bullpup rifle, finding service with the armed forces of over twenty countries. It was highly advanced for the 1970s, combining in the same weapon the bullpup configuration, a polymer housing, dual vertical grips, an optical sight as standard, and a modular design. Highly reliable, light, and accurate, the Steyr AUG showed clearly the potential of the bullpup layout. In 1978, France introduced the 5.56×45mm
FAMAS bullpup rifle. In 1985, the British introduced the 5.56×45mm
L85 bullpup rifle. In the late 1990s, Israel introduced the 5.56mm NATO
Tavor TAR-21. In 1997, China adopted the
QBZ-95 in the new
5.8×42mm cartridge, which they claim is superior to both the 5.56×45mm and the 5.45×39mm. By the turn of the century, the bullpup assault rifle design had achieved worldwide acceptance.
