A Brief History of the Assault Rifle.
The gun's name may have been coined by Adolf Hitler.
by MICHAEL SHURKIN.
JUN 30, 2016 While immediately after World War II, NATO countries were equipped with battle rifles, the development of the M16 rifle during the Vietnam War prompted the adoption of assault rifles by the rest of NATO.
By the end of the 20th century, assault rifles had become the standard weapon in most of the world's armies, replacing full-powered rifles and sub-machine guns in most roles.
Some of the most successful assault rifles include the AK-47, M16, IMI Galil and Heckler & Koch G36.
Origin of term
The term assault rifle is generally attributed to Adolf Hitler, 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.Musgave, Daniel D., and Thomas B. Nelson, The World's Assault Rifles, vol. II, The Goetz Company, Washington, D.C. (1967)
Myatt, Major Frederic, Modern Small Arms, Crescent Books, New York (1978): 169Hogg, Ivan, and John Weeks, Military Small Arms of the 20th Century, third ed., Hippocrene Books, New York (1977): 159Chris Bishop, The Encyclopedia of Weapons of World War II, Sterling Publishing Company, Inc., 2002, p. 218Military Small Arms of the 20th Century, 7th Edition, Ian V. Hogg, page 243 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.
Characteristics
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 or battle rifle, examples of intermediate cartridges are the 7.92×33mm Kurz, the 7.62x39mm and 5.56×45mm NATO.
Its ammunition must be supplied from a detachable box magazine.
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:
Select-fire M2 Carbines are not assault rifles; their effective range is only .Jane's Gun Recognition Guide.

page 330
Select-fire rifles such as the Fedorov Avtomat, FN FAL, 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.
The more political term assault weapon is often conflated with assault rifle and does not require all of the characteristics above – especially the selective fire capability which is functionally illegal in the U.S. for civilian use.
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 an 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."

2009 They would soon develop a select-fire intermediate powered rifle combining the firepower of a submachine gun with the range and accuracy of a rifle.
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.http://pogoarchives.org/labyrinth/09/02.pdf  M16 Rifle Case Study.

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.Military Small Arms of the 20th Century.

page 242–243 "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."

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.Weapon Of Mass Destruction .

The Guardian, Thursday 9 October 2003 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 has been continually worked upon, and improved.
The AKM, AK-74, and AK-12 were all designed by Mikhail Kalashnikov, and have all been service rifles in the Soviet Union, and the later Russian federation.
The AK-47 was widely supplied or sold to nations allied with the USSR, and the blueprints were shared with several friendly nations (the People's Republic of China standing out among these with the Type 56).
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."
Battle rifles
The U.S. Army was influenced by combat experience with semi-automatic weapons such as the M1 Garand 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.The M16.

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  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, South Africa and Sweden introduced AK type assault rifles in 5.56×45mm.Military Small Arms of the 20th Century.

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".Military Small Arms Of The 20th Century, 7th Edition, 2000 by Ian V. Hogg & John S. Weeks, p. 166 "Nevertheless, as a short-range weapon it is quite adequate and thus, [despite] its caliber, [the Colt Commando] is classed as a submachine gun."
Other compact assault rifles, such as the HK53, AKS-74U and the Daewoo K1, have been made and they have also been called submachine guns.Military Small Arms of the 20th Century.

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.
Heckler & Koch G36
The Heckler & Koch G36 is a 5.56×45mm assault rifle, designed in the early 1990s by Heckler & Koch in Germany as a replacement for the heavier G3.
It was accepted into service with the Bundeswehr in 1997, replacing the G3.Woźniak, Ryszard.

The G36 is gas-operated and feeds from a 30-round detachable box magazine or 100-round C-Mag drum magazine.
The G36 was made with the extensive use of lightweight, corrosion-resistant synthetic materials in its design; the receiver housing, stock, trigger group (including the fire control selector and firing mechanism parts), magazine well, handguard and carrying handle are all made of a carbon fiber-reinforced polyamide.
The receiver has an integrated steel barrel trunnion (with locking recesses) and a nylon 66 steel reinforced receiver.US5513461A - Light-weight automatic rifle.

The standard Bundeswehr versions of the G36 are equipped with a unique ZF 3×4° dual optical sight that combines a 3× magnified telescopic sight and an unmagnified reflex sight mounted on top of the telescopic sight.
Widely distributed, it has been adopted by over 40 countries and prompted other nations to develop similar composite designs, such as the FX-05 Xiuhcoatl.
Distinction from assault weapons
The term "assault rifle" is sometimes used interchangeably with the term "assault weapon", a legislative term used to classify firearms in the United States.
According to the Associated Press Stylebook, "although the terms are often used interchangeably, some make the distinction that assault rifle is a military weapon with a selector switch for firing in either fully automatic or semi-automatic mode from a detachable, 10- to 30-round magazine."
In the U.S., 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.
