1918-1942
Since the “assault rifle” ban in the United
States (1994 to 2004), a lot of public debate in Canada has gone into what an assault
“style” rifle is. Rifles and assaulting
being of professional interest to soldiers, below is an account of some
elements of the evolution of assault style military rifles.
We start with the Browning Automatic Rifle
(M1918). Designed by the legendary John
Moses Browning, it was to be used by American troops in the assault of German trenches
in World War I. Many of the assaulting
troops would carry these things. Upon
leaving the trench, the BAR-man would fire a round from the hip every time his
left foot hit the ground to keep enemy heads down - so-called walking fire -
and in the final assault, the rifle would be switched into automatic mode. The BAR fired the full powered .30-06
Springfield cartridge, and was, of necessity, long and heavy to be controllable
when employed in full auto mode from the hip.
It was fed by a 20 round detachable box magazine, which gave it a lot of
firepower for the day. The BAR was not
designed for clearing trenches, just getting there.
Despite its original purpose, the BAR is
not considered an assault rifle. It’s
too heavy and unwieldy for close-in work - as it had to be because it fires a
full-powered rifle cartridge. The BAR
was never tactically deployed in WWI, and was used as a squad support weapon in
WWII and Korea.
Also developed in WWI was the Bergmann
MP-18 (Maschinenpistole 18), the
first submachine gun. It was issued to German sturmtruppen in 1918. It
fired the 9 mm Parabellum pistol cartridge.
Shorter and handier than a rifle, it was effective in trench
fighting. Submachine guns are not
considered to be assault rifles because the cartridges they fire lack power and
range. Since submachine guns typically
fire from an open bolt, they lack useful accuracy beyond 50 yards, whereas
rifles are accurate beyond 300 yards.
Between the wars, the British developed the
famous Bren light machine gun. It was
purpose built as a squad support weapon, and features a quick detachable,
replaceable barrel; meaning it isn’t a rifle. The Bren could be used in
walking-fire mode. Because it has a
replaceable barrel, the Bren is a step up from the BAR.
The German MP-38/40 submachine guns,
designed by Hugo Schmeisser, are not considered assault rifles: the 9 mm
cartridge lacks power and range, and the weapons simply lack the accuracy of a
rifle. The Machine Pistol idea will be
important later in the war.
The M1 Carbine was developed befor the United
States entered WWII. It fires the .30
Carbine cartridge, which is like a hot .357 Magnum – powerful but still
pistol-ish. The M1 Carbine was developed
to replace the Colt M1911 handgun. The
M2 Carbine is the fully automatic version of the M1. The M2 is on the verge of being considered an
assault rifle because it’s select fire, but the cartridge is a little light for
serious rifle work, and the M2 Carbine is not considered an assault rifle by
the experts.
In WWII, the Germans developed the FG-42, a
rifle for their parachute troops. This
rifle is short, light, and handy for a rifle.
The 20 round detachable box magazine enters the left side of the
receiver above the trigger group. It
fires the full powered 7.92x57mm Mauser cartridge, and is select fire. It was designed to fill the gap when the
squad LMG, the Maschinengewehr (MG)-34,
wasn’t available. (The disastrous
assault on Crete was behind its development.)
Though modern even by today’s standards, the FG-42 is not considered an
assault rifle because that full-powered cartridge makes the rifle hard to
control in full-auto fire unless the bipod is deployed and the rifleman is
prone behind it. It was not designed for
clearing trenches or rooms; it was a paratrooper’s rifle (Fallschirmjagergewehr).

1943-1960
The first “assault rifle” was designed by Hugo
Schmeisser (of MP-38/40 fame) between 1938 and 1943; it represented his vision
of the next generation of military firearm, combining the attributes of a
submachine gun with a rifle. It was
designated the StG-43, succeeded later by the StG-44/MP-44. StG
stands for “Sturmgewehr”, literally
storm rifle, following sturmtruppen.
Storming was something the Nazis thought was grand - the party published a
weekly newspaper called “Der Sturmer.” From sturm
we get storming or “assault.”
Giving it the sexy name “sturmgewehr” (vice the technical designation
maschinenkarabiner machine, or
automatic, carbine) was a way of selling the concept to Hitler, who didn’t buy
it anyway because he wanted semi-automatic sniper rifles developed for mass
production. The program was renamed
MP-44, for Hitler would accept new development in submachine guns. The StG-43/MP-44 was select fire, chambered
the 8 mm Kurz intermediate power cartridge, was short, reasonably light, and
handy. It was fed by a 30 round
detachable box magazine. The 7.92X33 mm
Kurz was created by shortening the parent Mauser case, and using a bullet of
the same diameter but of shorter length, reducing bullet weight from 198 to 125
grains. Recoil from the 8 mm Kurz was
significantly lessened. The MP-44 put a
lot of easy, controllable firepower into the hands of the infantry soldier, and
the rifle could still reach out effectively beyond 300 m. The troops loved it. It was automatic like a submachine gun, and
not as punishing as the Mauser K98k.
During WWII, the Soviets were famous for
their submachine guns and their tank riders.
After the war, the AK-47 was developed based on the example of the
MP-44, and was to replace the submachine gun in Soviet service carried by the
tank riders. The AK-47 was select fire,
and was supplied by a 30 round detachable box magazine. It fired the 7.62x39 mm cartridge, first
developed for the SKS. The AK-47 is
considered an assault rifle even though originally deployed as a submachine gun
replacement; it was, however, carried by assault troops.
The SKS, fielded in 1945, was designed to
be the replacement for the Mosin-Nagant 91/30 in Soviet service. It was semi-automatic only, was fed by a 10
round internal magazine, and chambered the 7.62x39 mm cartridge. The SKS is not considered an assault rifle.
After WWII, the U.S. developed the M-14 to
replace the M1 Garand. The M-14 was
designed to be select fire, but the cartridge it chambered was the full power
7.62x51 mm NATO cartridge, making this light-ish rifle uncontrollable in full
auto mode. Neither the M1 Garand nor the
M-14 are considered assault rifles.
Now we come to another American firearms
genius, Eugene Stoner. His first major
offering was the Armalite AR-10. It
chambered the 7.62X51 mm NATO cartridge and was fed from a 20 round detachable
box magazine. Employing aluminum and
plastic, it was remarkably light and handy; its straight line design made it
more controllable than the M-14 in full auto fire, but you still couldn’t clear
a room with one on full auto like you can with a submachine gun. The AR-10 came too late in trials to be
accepted by the U.S. military, but it was manufactured under license overseas and
sold to a number of militaries of minor countries during the 1960s.
The AR-15 was a miniaturization of the
AR-10. Stoner developed a bullet for the
notably accurate .222 Remington cartridge, so that it would pass a military
test for lethality; and with some tinkering, the .223 Remington was born. The AR-15 chambered it. The USAF was interested in replacing their M1
and M2 Carbines with which their guard troops were equipped, and the AR-15
attracted favourable attention. Colt
also attracted interest in the AR-15 from East Asian countries, whose soldiers
were often 5’2” and 120 lbs. The M1
Garand, which the U.S. offered in military aid, were beasts for soldiers of
that size, and the AR-15 sold itself.
########################################################################
1960-1967
Armalite sold its patents on the AR-10 and
-15 to Colt in 1960. Because of problems
manufacturing the M-14 and of the pressing needs of the war in Vietnam, the
U.S. DoD began, in 1963, ordering AR-15s, designated the XM-16E1, in hundreds
of thousands to fill the gap until something better was developed and in
production.
Well, it turned out that nothing better
came along, and the M-16 and its lineal descendants remain the standard issue
service rifle in the U.S. today.
The AR-15 today now refers to a
semi-automatic only version of the original Stoner rifle and its subsequent
modifications. Colt started selling semi-automatic
rifles branded “Colt AR-15” on the civilian market in 1964, the same time Colt
began filling large US military contracts.
These rifles were made semi-automatic by deleting the auto sear from the
trigger group. Hence, our question is,
“is the M-16 an assault rifle?”
The M-16 fires an intermediate power
cartridge and is select fire. It’s controllable
in full auto mode, can fill the role of a submachine gun but not that of a
light machine gun. By these criteria,
the M-16 is an “assault” rifle, though it was never developed with the
“assault” intention in mind. It was
intended to be the next generation service rifle, superior to the M2 Carbine; and
not to fill a niche role, as the AK-47 was.
Assaulting positions in a human-wave charge like in WWI, while firing
something in full auto mode, simply isn’t in the U.S. infantry manual - anymore. Technically, the M-16 meets all the criteria
of an assault rifle; so, yes, an expert would say that the M-16 qualifies as an
assault rifle, but I put an asterisk next to it because “sturm” nowhere enters this picture.
The non-intentional and technically accurate “automatic carbine” (maschinenkarabiner) is its proper
classification, in my view.
After the AR-15, Eugene Stone came up with
the AR-18 concept. Where the AR-15 uses
a direct impingement gas system, the AR-18 uses a short-stroke piston to cycle
the action. The AR-18 is much like the
AR-15 in design purpose - an automatic carbine - but was intended to be
manufactured in third world countries, required little sophisticated machining
to build, and it got around the direct-gas impingement patent owned then by
Colt. Also chambering the .223
Remington, the AR-18 was made in a few thousands; it’s most famous descendent
is the British SA-80. The SA-80 is a bullpup arrangement, and meets
all the criteria of an assault rifle; but like the M-16, it was developed as
the next-generation, general-issue service rifle and not for a specific niche
role. The AR-180 is the semi-automatic
version of the AR-18, and was sold on the civilian market.
The last Stoner design we’ll consider is
the Stoner 63. This interesting firearm
could be configured in six different ways, including: as a rifle, a carbine, a
Bren style automatic rifle, and a belt-fed light machine gun. It was adopted by the U.S. Navy SEALs in 1967,
and used in Vietnam primarily in the belt-fed LMG configuration. With a 15” barrel, a 100 or 150 round belt in
a box underneath the receiver, the Stoner could be rested on the ground using
the box housing in place of a bipod, and a squad of four SEALs could put out
the firepower of a platoon. It was
remarkably light and controllable, which is why it was so popular in
Vietnam. The Stoner, as configured by
the SEALs, is a world-beater for clearing trenches, rooms, and jungle clearings
as required, and for any other assault purpose; but only in its rifle and
carbine configurations would it be classed as an “assault rifle.” Technically, the
preferred SEAL configuration is an LMG.
The Canadian FN C1 and C2 are not assault
rifles. They are long, and fire the full
power 7.62 NATO cartridge. The C1 was
not intended to fire in full auto, though the sear can be slipped to make it do
so. It is uncontrollable in full
automatic fire, as is the C2 when fired standing. The C2 fills the same role as the BAR: a second-rate
squad support weapon.
The purpose-built “assault rifles” covered
here are the BAR and the AK-47. All the automatic
carbines are, by intention, improved, general issue, next-generation service
rifles, whose principle improvement is the ability to fill the role of a
submachine gun. The expression “assault
rifle” was originally coined to sell the new rifle concept to Adolph Hitler,
the term “sturm” having a cachet
among Nazis. Hitler wasn’t seduced, and
so the concept was continued in development, in spite of him, as a new
submachine gun, the MP-44. After the
war, the sturmgewehr concept was
translated and accepted as “assault rifle” which was a rifle (a carbine,
really) with certain characteristics: select fire, intermediate powered cartridge,
magazine fed, controllable in full auto, and capable of filling the role of a
submachine gun. The experts typically
don’t consider the intended role of the weapon in the classification of a rifle
being an “assault rifle” or not, and perhaps they ought to adopt the non-
intentional, and technically accurate, expression “automatic carbine.” Fully automatic rifles weren’t designed to
“kill as many cabinet members as possible in the shortest time;” they were
designed to win the fire-fight by putting more rounds downrange than the enemy
was.
The public debate over what constitutes an
assault rifle in style amounts to a
discussion of undeclared, unexamined prejudices in disguise, with the
opportunity to employ illicit substitutions in argument. “Style” in this case, means that the things
in question don’t actually possess the offending automatic characteristic: they
only resemble the offending thing stylistically; and “assault” sounds so
terrifying, menacing, and insensitive.
