The Browning Automatic Rifle (BAR) was a family of United States automatic rifles (or machine rifles) and light machine guns used by the United States and numerous other countries during the 20th century. The primary variant of the BAR series was the M1918, chambered for the .30-06 Springfield rifle cartridge and designed by John Browning in 1917 for the U.S. Expeditionary Corps in Europe as a replacement for the French-made Chauchat and M1909 Benet-Mercie machine guns.
The BAR was designed to be carried by advancing infantrymen, slung over the shoulder or fired from the hip, a concept called "walking fire"—thought to be necessary for the individual soldier during trench warfare. However in practice, it was most often used as a light machine gun and fired from a bipod (introduced in later models). A variant of the original M1918 BAR, the Colt Monitor Machine Rifle, remains the lightest production automatic gun to fire the .30-06 Springfield cartridge, though the limited capacity of its standard 20-round magazine tended to hamper its utility in that role.
Although the weapon did see some action in World War I, the BAR did not become standard issue in the U.S. Army until 1938 when it was issued to squads as a portable light machine gun. The BAR saw extensive service in both World War II and the Korean War and saw some service early in the Vietnam War. The U.S. Army began phasing out the BAR in the late 1950s and was without a portable light machine gun until the introduction of the M249 Squad Automatic Weapon in the mid-1980s.

History[edit | edit source]
The U.S. entered World War I with an inadequately small and obsolete assortment of various domestic and foreign machine gun designs, due primarily to bureaucratic indecision and the lack of an established military doctrine for their employment. When the declaration of war on Imperial Germany was announced on 6 April 1917, the military high command was made aware that to fight this machine gun-dominated trench war, they had on hand a mere 670 M1909 Benet-Mercies, 282 M1904 Maxims and 158 Colts, M1895. After much debate, it was finally agreed that a rapid rearmament with domestic weapons would be required, but until that time, U.S. troops would be issued whatever the French and British had to offer. The arms donated by the French were often second-rate or surplus and chambered in 8mm Lebel, further complicating logistics as machine gunners and infantrymen were issued different types of ammunition.
Development[edit | edit source]
In 1917, prior to America's entry to the war, John Browning personally brought to Washington, D.C. two types of automatic weapons for the purposes of demonstration: a water-cooled machine gun (later adopted as the M1917 Browning machine gun) and a shoulder-fired automatic rifle known then as the Browning Machine Rifle or BMR, both chambered for the standard U.S. .30-06 Springfield cartridge. Browning had arranged for a public demonstration of both weapons at a location in southern Washington, D.C. known as Congress Heights. There, on 27 February 1917, in front of a crowd of 300 people (including high-ranking military officials, Congressmen, Senators, foreign dignitaries and the press), Browning staged a live fire demonstration which so impressed the gathered crowd, that he was immediately awarded a contract for the weapon and it was hastily adopted into service (the water-cooled machine gun underwent further testing).
Additional tests were conducted for U.S. Army Ordnance officials at Springfield Armory in May 1917 and both weapons were unanimously recommended for immediate adoption. In order to avoid confusion with the belt-fed M1917 machine gun, the BAR came to be known as the M1918 or Rifle, Caliber .30, Automatic, Browning, M1918 according to official nomenclature. On 16 July 1917, 12,000 BARs were ordered from Colt's Patent Firearms Manufacturing Company who had secured an exclusive concession to manufacture the BAR under Browning's patents (Browning's U.S. Patent 1,293,022 was owned by Colt). However Colt was already producing at peak capacity (contracted to manufacture the Vickers machine gun for the British Army) and requested a delay in production while they expanded their manufacturing output with a new facility in Meriden, Connecticut. Due to the urgent need for the weapon, the request was denied and the Winchester Repeating Arms Company (WRAC) was designated as the prime contractor. Winchester gave valuable assistance in refining the BAR's final design, correcting the drawings in preparation for mass production. Among the changes made, the ejection pattern was modified (spent casings were directed to the right side of the weapon—instead of straight up).
Initial M1918 Production[edit | edit source]
Since work on the gun did not begin until February 1918, so hurried was the schedule at Winchester to bring the BAR into full production that the first production batch of 1,800 guns was delivered out of spec; it was discovered that many components did not interchange between rifles and production was temporarily halted until manufacturing procedures were upgraded to bring the weapon up to specifications. The initial contract with Winchester called for 25,000 BARs. They were in full production by June 1918, delivering 4,000 guns, and starting in July were turning out 9,000 units a month.
Colt and Marlin-Rockwell Corp. also began production shortly after Winchester got into full production. Marlin-Rockwell, burdened by a contract to make rifles for the Belgian government, acquired the Mayo Radiator Co.'s factory and used it exclusively to carry out production of the BAR. The first unit from this source was delivered on 11 June 1918 and the company's peak output reached 200 automatic rifles per day. Colt had only produced 9,000 BARs by the time of the armistice due to the heavy demands of previous orders. These three companies produced a combined daily output of 706 rifles and a total of approximately 52,000 BARs were delivered by all sources by the end of the war. Between 1918 and 1919, 102,125 BARs had been manufactured jointly by Colt (16,000 weapons), Winchester (47,123) and Marlin-Rockwell (39,002 units).
By July 1918, the BAR had begun to arrive in France, and the first unit to receive them was the U.S. Army's 79th Infantry Division, which took them into action for the first time on 13 September 1918. The weapon was personally demonstrated against the enemy by 2nd Lieutenant Val Allen Browning, the inventor's son. Despite being introduced very late in the war, the BAR made an impact disproportionate to its numbers; it was used extensively during the Meuse-Argonne Offensive and made a significant impression on the Allies (France alone requested 15,000 automatic rifles to replace their notoriously unreliable Chauchat machine rifle).
Design details and accessories[edit | edit source]
The M1918 is a selective fire, air-cooled automatic rifle using a gas-operated long-stroke piston rod actuated by propellant gases bled through a vent in the barrel. The bolt is locked by a rising bolt lock. The gun fires from an open bolt. The spring-powered cartridge casing extractor is contained in the bolt and a fixed ejector is installed in the trigger group. The BAR is striker fired (the bolt carrier serves as the striker) and uses a trigger mechanism with a fire selector lever that enables operating in either semi-automatic or fully automatic firing modes. The selector lever is located on the left side of the receiver and is simultaneously the manual safety (selector lever in the "S" position – weapon is "safe", "F" – "Fire", "A" – "Automatic" fire). The "safe" setting blocks the trigger.
The weapon's barrel is screwed into the receiver and is not quickly detachable. The M1918 feeds using double-column 20-round box magazines, although 40-round magazines were also used in an anti-aircraft role; these were withdrawn from use in 1927. The M1918 has a cylindrical flash suppressor fitted to the muzzle end. The original BAR was equipped with a fixed wooden buttstock and closed-type adjustable iron sights, consisting of a forward post and a rear leaf sight with 100 to 1,500 yard range graduations.
As a heavy automatic rifle designed for support fire, the M1918 was not fitted with a bayonet mount and no bayonet was ever issued. Only one experimental bayonet fitting was ever made for the BAR by Winchester. This was a standard, M1917 bayonet fitted at the Winchester factory with a special muzzle ring. The bayonet was attached to a standard M1918 BAR by means of a special experimental flash hider assembly. This prototype bayonet/flash hider assembly came from the Winchester in-house factory museum in New Haven, Connecticut with a tag printed on one side Winchester Repeating Arms Co./New Haven Conn., and handwitten on the other side: Combined Flash Hider, Front Sight and Bayonet Mount for Browing Automatic Rifle Model 1918 with Bayonet and Scabbard and the date - September 7, 1918. There is no evidence whatsoever of military adoption nor a military stock number, name, or classification.
Variants and subsequent models[edit | edit source]
During its lengthy service life, the BAR underwent continuous development, receiving many improvements and modifications. The first major attempt at improving the M1918 resulted in the M1922 light machine gun, adopted by the United States Cavalry in 1922. The weapon used a new heavy profile ribbed barrel, an adjustable spiked bipod (mounted to a swiveling collar on the barrel) with a rear, stock-mounted monopod, a side-mounted sling swivel and a new rear endplate, fixed to the stock retaining sleeve. The handguard was changed, and in 1926, the BAR's sights were redesigned to accommodate the heavy-bullet 172-grain M1 .30-06 ball ammunition then coming into service for machine gun use.
In 1931, the Colt Arms Co. introduced the Colt Monitor Automatic Machine Rifle (R 80), intended primarily for use by prison guards and law enforcement agencies. Intended for use as a shoulder-fired automatic rifle, the Colt Monitor omitted the standard bipod, instead featuring a separate pistol grip and buttstock attached to a lightweight receiver, along with a shortened 458 mm (18.0 in) barrel fitted with a 4-inch (100 mm) Cutts compensator. Weighing 16 lb. 3 oz. empty, the Colt Monitor had a rate of fire of approximately 500 rpm. Around 125 Colt Monitor automatic machine rifles were produced; of these ninety were purchased by the . Eleven rifles went to the U.S. Treasury Department in 1934, while the rest went to various state prisons, banks, security companies, and accredited police departments. Although the Colt Monitor was available for export sale, no examples appear to have been exported to other countries. In 1932, a greatly shortened version of the M1918 BAR designed for 'bush warfare' was developed by USMC Major H.L. Smith, and was the subject of an evaluative report by Capt. Merritt A. Edson, Ordnance officer at the Quartermaster's Depot in Philadelphia, Pennsylvania. The barrel was shortened nine inches (229 mm) at the muzzle, and the gas port and gas cylinder tube were relocated. The modified BAR weighed 13 lb. 12 oz. and was only 34.5 inches (880 mm) long overall. Though it proved superior to the M1918 in accuracy when fired in automatic mode using the prone position, and equal in accuracy to the standard M1918 at ranges of 500-600 yards when fired from a rest, it was less accurate when fired from the shoulder, and had a loud report combined with a fierce muzzle blast. Attaching a Cutts compensator materially reduced the muzzle blast, but this was more than offset by the increase in smoke and dust at the muzzle when fired, obscuring the operator's vision. Nor did it improve control of the weapon when fired in bursts of automatic fire. Though the report recommended building six of these short-barrelled 'jungle' BARs for further evaluation, no further work was done on the project. The M1918A1, featuring a lightweight spiked bipod, with a leg height adjustment feature, attached to the gas cylinder and a hinged steel butt plate, was formally approved on 24 June 1937. The M1918A1 was intended to increase the weapon's effectiveness and controllability firing in bursts. Relatively few M1918s were rebuilt to the new M1918A1 standard.
In April 1938, work was commenced on an improved BAR for the U.S. Army. The latter specified a need for a BAR designed to serve in the role of a light machine gun for squad-level support fire. Early prototypes were fitted with barrel-mounted bipods, as well as pistol grip housings and a unique rate-of-fire reducer mechanism purchased from FN Herstal. The rate reducer mechanism performed well in trials, and the pistol grip housing enabled the operator to fire more comfortably from the prone position. However, in 1939 the Army declared that all modifications to the basic BAR be capable of being retrofitted to earlier M1918 guns with no loss of parts interchangeability. This effectively killed the FN-designed pistol grip and its proven rate reducer mechanism for the new M1918 replacement.
Final development of the M1918A2 was authorized on 30 June 1938. The FN-designed pistol grip and rate-reducer mechanism with two rates of automatic fire was shelved in favor of a rate-reducer mechanism designed by Springfield Armory, and housed in the buttstock. The Springfield Armory rate reducer also provided two selectable rates of fully automatic fire only, activated by engaging the selector toggle. Additionally, a skid-footed bipod was fitted to the muzzle end of the barrel, magazine guides were added to the front of the trigger guard, the handguard was shortened, a heat shield was added to help the cooling process, a small separate stock rest (monopod) was included for attachment to the butt, and the weapon's role was changed to that of a squad light machine gun. The BAR's rear sight scales were also modified to accommodate the newly standardized M2 Ball ammunition with its lighter, flat-base bullet. The M1918A2 walnut buttstock is approximately one inch longer than the M1918 BAR buttstock. The M1918A2 barrel was also fitted with a new flash suppressor, and fully adjustable iron sights. Late in the war, a barrel-mounted carrying handle was added.
Because of budget limitations, initial M1918A2 production consisted of conversions of older M1918 BARs (remaining in surplus) along with a limited number of M1922s and M1918A1s. After the outbreak of war, attempts to ramp up new M1918A2 production were stymied by the discovery that the World War I tooling used to produce the M1918 was either worn out or incompatible with modern production machinery. New production was first undertaken at the New England Small Arms Corp. and International Business Machines Corp. (a total of 168,000 new weapons were manufactured). In 1942, a shortage of black walnut for buttstocks and grips led to the development of a black plastic buttstock for the BAR. Composed of a mixture of Bakelite and Resinox, and impregnated with shredded fabric, the buttstocks were sandblasted to reduce glare. Firestone Rubber and Latex Products Company produced the plastic buttstock for the U.S. Army, which was formally adopted on March 21, 1942. Production rates greatly increased in 1943 after IBM introduced a method of casting BAR receivers from a new type of malleable pig iron developed by the Saginaw division of General Motors, called ArmaSteel. After successfully passing a series of tests at Springfield Armory, the Chief of Ordnance instructed other BAR receiver manufacturers to change over from steel to ArmaSteel castings for this part. During the Korean War, M1918A2 production was resumed, this time contracted to the Royal McBee Typewriter Co., which produced an additional 61,000 M1918A2s.
Contemporary models[edit | edit source]
In 2008, Ohio Ordnance Works introduced a modern, semi-automatic version of the Browning Automatic Rifle known as the 1918 A 3-SLR ("self-loading rifle").
International and Commercial models[edit | edit source]
Export models[edit | edit source]
The BAR also found a ready market overseas and in various forms was widely exported. In 1919, the Colt's company developed and produced a commercial variant called the Automatic Machine Rifle Model 1919 (company designation: Model U), which has a different return mechanism compared to the M1918 (it is installed in the stock rather than the gas tube) and lacks a flash hider. Later the Model 1924 rifle was offered for a short period of time, featuring a pistol grip and a redesigned handguard. These Colt automatic rifles were available in a number of calibers, including .30-06 Springfield (7.62x63mm), 7.65x53mm Belgian Mauser, 7x57mm Mauser, 6.5x55mm, 7.92x57mm Mauser and .303 British (7.7x56mmR). All of the 6.5x55mm-caliber Colt automatic rifles appear to have been sold directly to FN. An improved version of the Model 1924, the Model 1925 (R75) would achieve the highest popularity in export sales. It is based on the Model 1924 but uses a heavy, finned barrel, a lightweight bipod and is equipped with dust covers in the magazine well and ejection port (some of these features were patented: refer to US patents 1548709 and 1533968). The Model 1925 was produced in various calibers, including .30-06 Springfield (7.62x63mm), 7.65x53mm Belgian Mauser, 7x57mm Mauser, 7.92x57mm Mauser, and .303 British (7.7x56mmR) (no Colt-manufactured Model 1925 rifles in 6.5x55mm appear to have been sold). A minor variant of the Model 1925 (R75) was the R75A light machine gun with a quick-change barrel (produced in 1924 in small quantities for the Dutch Army). Between 1921 and 1928, FN Herstal imported over 800 Colt-manufactured examples of the Colt Machine Rifles for sale abroad. All of the Colt automatic machine rifles, including the Colt Monitor, were available for export sale. After 1929, the Model 1925 and the Colt Monitor were available for export sale in Colt's exclusive sales territories per its agreement with FN. These Colt territories included North America, Central America, the West Indies, South America, Great Britain, Russia, Turkey, Siam (Thailand), India, and Australia.
Belgium[edit | edit source]
A variant known as the FN Mle 1930 was developed in 7.65x53mm Belgian Mauser by FN Herstal and adopted by the Belgian Army. The Mle 1930 is basically a licensed copy of the Colt Automatic Machine Rifle, Model 1925 (R 75). The Mle 1930 had a different gas valve and a mechanical rate-reducing fire control mechanism designed by Dieudonne Saive, housed in the trigger guard/pistol grip housing. Some of these FN rate reducer mechanisms and pistol grip housings were later purchased by Springfield Armory for evaluation and possible adoption on a replacement for the M1918. The weapon also had a hinged shoulder plate and was adapted for use on a tripod mount. In 1932, Belgium adopted a new version of the FN Mle 1930 allocated the service designation FN Mle D (D—Demontable or "removable") which had a quick-change barrel, shoulder rest and a simplified take-down method for eased cleaning and maintenance. The Mle D was produced even after World War II in versions adapted for .30-06 Springfield and NATO-standard 7.62x51mm ammunition.
The final variant in Belgian service was the Model DA1 chambered for the 7.62x51mm NATO cartridge and feeding from the 20 round magazines for the FN FAL rifle.
Poland[edit | edit source]
Production of the BAR in Belgium began only after signing an agreement with Poland (on 10 December 1927) involving the procurement of 10,000 wz. 1928 light machine guns chambered in 7.92x57mm Mauser, which are similar to the R75 variant but designed specifically to meet the requirements of the Polish Army. Changes to the base design include a pistol grip, different type of bipod, open-type V-notch rear sight and a slightly longer barrel. Subsequent rifles were assembled locally in Poland under license by the State Rifle Factory (Państwowa Fabryka Karabinów) in Warsaw. The wz. 1928 was accepted into service with the Polish Army in 1927 under the formal name 7,92 mm rkm Browning wz. 1928 ("7.92 mm Browning hand-held machine gun model 1928") and – until the outbreak of World War II – was the primary light support weapon of Polish infantry and cavalry formations (in 1939 Poland had a total of approx. 20,000 wz. 1928 rifles in service). Additional detail modifications were introduced on the production line. Among them was the replacement of the iron sights with a smaller version and reshaping the butt to a fish tail.
In the mid-1930s, Polish small arms designer Wawrzyniec Lewandowski was tasked with developing a flexible aircraft-mounted machine gun based on the Browning wz.1928. This resulted in the wz. 1937. Changes included increasing the weapon's rate of fire to 1,100 rounds/min, eliminating the buttstock, adding a spade-type grip to the rear of receiver, moving the main drive spring under the barrel and most importantly – changing the feed system. Sustained fire was practically impossible with the standard 20-round box magazine thus a new feed mechanism was developed, which was added to the receiver as a module. It contains a spring-loaded bolt-actuated lever, which would feed a round from a 91-round pan magazine located above the receiver and force the round into the feed path during unlocking. The machine gun was accepted in 1937 and ordered by the Polish Air Force as the karabin maszynowy obserwatora wz. 1937 ("observers machine gun model 1937"). 339 machine guns were eventuality acquired and used as armament in the PZL.37 Łoś medium bomber and the LWS-3 Mewa reconnaissance aircraft.
Sweden[edit | edit source]
In 1920, the Belgian arms manufacturer Fabrique Nationale (FN) acquired sales and production rights to the BAR series of firearms in Europe from Colt. The first BAR model sold by FN was the Kg m/21 (Kg—Kulsprutegevär or "machine rifle") chambered for the 6.5x55mm m/94 cartridge. The m/21 is a variant of the Model 1919 designed to Swedish specifications and manufactured initially by Colt's and later under license at the Carl Gustafs Stads Gevärsfaktori in Eskilstuna. Compared to the Model 1919, the Swedish weapon has—apart from the different caliber—a spiked bipod and pistol grip. The m/21 would become one of Sweden's main support weapons in the interwar years together with the water-cooled belt-fed Ksp m/1914 medium machine gun (Swedish adaptation of the Austrian M07/12). Dissatisfied with the rapidly overheating fixed barrel of the m/21, Carl Gustaf began to design a new quick-detach mechanism for the barrel which mates the externally grooved chamber to a series of rotating flanges in the receiver operated by a locking lever. The barrel also received cooling fins along its entire length. These enhancements were incorporated into the fm/1935 prototype which was favorably evaluated during trials in 1935. The final version was the Kg m/37, adopted for service in 1937, which uses a smooth contour, unfinned barrel. Numerous m/21 guns were retrofitted with the screw-on receiver extension and quick-change barrel, and renamed the Kg m/21-37. The m/37 remained in service until being replaced by the FN MAG, but was still in second-line use until 1980. Carl Gustaf also developed a belt-fed prototype; however it was never adopted.
China[edit | edit source]
The Chinese Nationalist Army used the FN M1930 throughout the Second Sino-Japanese War. The Chinese BAR was chambered for the German 7.92x57mm Mauser round, the standard rifle cartridge of the National Revolutionary Army. After the outbreak of the Pacific War, the Chinese Expeditionary Army in Burma was equipped with American BARs. Towards the end of the war, small quantities of American equipment, including the BAR, made their way into mainland China.
Civilian use[edit | edit source]
With the cessation of WWI hostilities, Colt Arms Co. received the Browning patents to produce the BAR that had been withheld from issue during the war. This allowed Colt to make the BAR available for commercial sale, including sale to civilian owners. The Colt Automatic Machine Rifle Model 1919, initially made up of overruns from the M1918 military production contract, was the first of several commercial Colt BARs that would follow. However, the high price of the weapon and its limited utility for most civilian owners resulted in few sales. Ad Topperwien, a famous trick shooter of the early 1920s, purchased one of the first Colt-produced BARs to perform aerial target shooting exhibitions. Occasional BAR sales were made to civilian owners through distributors such as the Ott-Heiskell Hardware Co. In 1931, the new Colt Monitor was made available to civilians during the Depression at $300 each, including spare parts kit, sling, cleaning accessories, and six magazines, but Colt records indicate no domestic sales occurred to individuals. After passage of the National Firearms Act of 1934, civilian BAR ownership was restricted even further. Importation of machine guns for U.S. civilian transfer was banned in 1968, and U.S. production of machine guns for civilian transfer was banned in 1986. However, some transferable civilian-owned BAR models exist in the United States, and occasionally come up for sale to qualified buyers. Some companies are manufacturing semi-automatic copies for sale to civilians. Ohio Ordnance Works, Inc, in Chardon, Ohio holds an exclusive patent for the 1918A3-SLR (Self-Loading Rifle), which is a contemporary semi-automatic variant of the M1918 and is legal for civilians to own. 
Criminal and law enforcement use[edit | edit source]
Although the Colt Monitor version of the BAR failed to interest U.S. civilian buyers in the midst of the Depression, the underworld was a lot more interested: in 1936, the going price for a black-market Colt Monitor was $5,000, with military BARs going for somewhat less. The Army's M1918 was a favorite of gangster Clyde Barrow, who obtained his examples through periodic robberies of Army National Guard armories in the Midwest. Barrow liked to use armor-piercing (AP) .30-06 ammunition he obtained from armory stores, and frequently modified his BARs to suit his own needs. Barrow taught his 90-lb. girlfriend Bonnie Parker to fire the M1918 as well, and by all accounts the latter was an excellent BAR operator. Parker used a M1918 on full-automatic to pin down unsuspecting law officers after the latter confronted the gang at a house in Joplin, Missouri. A Missouri highway patrolman at the scene, forced to dive for cover behind a substantial oak tree after Bonnie Parker opened up on him, would later state: "That little red-headed woman filled my face with splinters on the other side of that tree with one of those damned guns!".
As the use of automatic weapons by gangster elements in the United States became more widespread, FBI director J. Edgar Hoover ordered the FBI to acquire and commence regular training with automatic shoulder weapons, including the Thompson submachine gun and the BAR. For its BARs, the FBI turned to Colt, which sold 90 Colt Monitor automatic machine rifles to the agency. Some of the FBI's Monitors were distributed to FBI field offices for use as support weapons if needed on a particular operation, while the remainder were retained at the FBI Academy in Quantico, Virginia for training purposes. Colt sold an additional 11 Colt Monitors to the U.S. Treasury Department in 1934, while 24 guns were sold to state prisons, banks, security companies, and accredited city, county, and state police departments. Although it has sometimes been alleged that the M1918 or M1918A2 Browning Automatic Rifle was used by members of the Symbionese Liberation Army (SLA) in their wild shootout with Los Angeles police on 17 May 1974, no SLA members ever used such a weapon. The confusion arose out of Browning's decision in the 1970s to also designate its semiautomatic hunting rifle the Browning BAR. The SLA converted a .30-06 Browning BAR hunting rifle and a .243 Remington Model 742 to automatic fire by crudely filing down the sear, and it was these weapons that were used in the shootout.
The BAR in U.S. military service[edit | edit source]
World War I[edit | edit source]
At its inception, the M1918 was intended to be used as a shoulder-fired rifle capable of both semi-automatic and fully automatic fire. First issued in September 1918 to the AEF, it was based on the concept of "walking fire", a French practice in use since 1916 for which the CSRG 1915 (Chauchat) had been used accompanying advancing squads of riflemen toward the enemy trenches, since the machine guns were too heavy to follow the troops during an assault.
In addition to shoulder-fired operation, BAR gunners were issued a belt with magazine pouches for the BAR and sidearm along with a "cup" to support the stock of the rifle when held at the hip. In theory, this allowed the soldier to lay suppressive fire while walking forward, keeping the enemy's head down, a practice known as "marching fire". The idea would resurface in the submachine gun and ultimately the assault rifle.
It is not known if any of the belt-cup devices actually saw combat use. The BAR saw little action in World War I, in part due to the Armistice, and also because the U.S. Army was reluctant to have the BAR fall into enemy hands; the gun saw its first action in September 1918. 85,000 BARs were built by the war's end.
Interwar use[edit | edit source]
During the interwar years, the BAR was standard issue to U.S. naval landing forces. The weapon was a standard item in U.S. ship armories, and each BAR was accompanied by a spare barrel. Large capital ships often had over 200 BARs on board. Many of the U.S. Navy BARs remained in service well into the 1960s. The BAR saw action with U.S. Marine Corps units participating in the Haitian and Nicaraguan interventions, as well as with U.S. Navy shipboard personnel in the course of patrol and gunboat duty along the Yangtze River in China. The First Marine Brigade stationed in Port-au-Prince, Haiti, noted that training a man to use the BAR proficiently took a full two days of range practice and instruction, compared to half a day with the .45 caliber Thompson submachine gun.
World War II[edit | edit source]
When the threat of a new war arose, Ordnance belatedly realized it had no portable squad light machine gun, and attempted to convert the M1918 BAR to that role with the adoption of the M1918A2 by the U.S. Army on 30 June 1938. The BAR was issued as the sole automatic fire support for a twelve man squad, and all men were trained at the basic level how to operate and fire the weapon in case the designated operator(s) were killed or wounded. At the start of the war, most infantry companies designated two- or three-man BAR teams, a gunner and one or two assistant gunners (ammo bearers) who carried extra loaded magazines for the gun. By 1944, some units were using one-man BAR teams, with the other riflemen in the squad detailed to carry additional magazines and/or bandoliers of .30 ammunition. The average combat lifespan of a World War II BAR man was estimated to be 30 minutes. Despite various claims on the subject, the BAR was issued to soldiers of various heights.
As originally conceived, U.S. Army tactical doctrine called for one M1918A2 per squad, using either one or two men to support and carry ammunition for the gun. Fire and movement tactics centered around the M1 riflemen in the squad, while the BAR man was detailed to support the riflemen in the attack and provide mobility to the riflemen with a base of fire. This doctrine received a setback early in the war after U.S. ground forces encountered German troops well-armed with automatic weapons, including fast-firing, portable machine guns. In some cases, particularly in the attack, every fourth German infantryman was equipped with an automatic weapon, either a submachine gun or a full-power machine gun. In an attempt to overcome the BAR's limited continuous-fire capability, U.S. Army combat divisions increasingly began to specify two BAR fire teams per squad, following the practice of the U.S. Marine Corps. One team would typically provide covering fire until a magazine was empty, whereupon the second team would open fire, thus allowing the first team to reload. In the Pacific, the BAR was often employed at the point or tail of a patrol or infantry column, where its firepower could help break contact on a jungle trail in the event of ambush. After combat experience showed the benefits of maximizing portable automatic firepower in squad-size formations, the U.S. Marine Corps began to increase the number of BARs in its combat divisions, from 513 per division in 1943 to 867 per division in 1945. A thirteen-man squad was developed, consisting of three four-man fire teams, with one BAR per fire team, or three BARs per squad. Instead of supporting the M1 riflemen in the attack, Marine tactical doctrine was focused around the BAR, with riflemen supporting and protecting the BAR gunner. Despite the improvements in the M1918A2, the BAR remained a difficult weapon to master with its open bolt and strong recoil spring, requiring additional range practice and training to hit targets accurately without flinching. As a squad light machine gun, the BAR's effectiveness was mixed, since its thin, non-quick-change barrel and small magazine capacity greatly limited its firepower in comparison to genuine light machine guns such as the British Bren or the Japanese Type 96. The weapon's rate-reducer mechanism, a delicately balanced spring-and-weight system described by one Ordnance sergeant as a "Rube Goldberg device", came in for much criticism, often causing malfunctions when not regularly cleaned. The bipod and buttstock rest (monopod), which contributed so much to the M1918A2's accuracy when firing prone on the rifle range, proved far less valuable under actual field combat conditions. The stock rest was dropped from production in 1942, while the M1918A2's bipod and flash hider were often discarded by individual soldiers and Marines to save weight and improve portability, particularly in the Pacific Theatre of war. With these modifications, the BAR effectively reverted to its original role as a portable, shoulder-fired automatic rifle.
Due to production demands, war priorities, subcontractor issues, and material shortages, demand for the M1918A2 frequently exceeded supply, and as late as 1945 some Army units were sent into combat still carrying older, unmodified M1918 weapons. After a period of service, ordnance personnel began to receive BARs with inoperable or malfunctioning recoil buffer mechanisms. This was eventually traced to the soldier's common practice of cleaning the BAR in a vertical position with the butt of the weapon on the ground, allowing cleaning fluid and burned powder to collect in the recoil buffer mechanism. Additionally, unlike the M1 rifle, the BAR's gas cylinder was never changed to stainless steel. Consequently, the gas cylinder frequently rusted solid from the use of corrosive-primered M2 service ammunition in a humid environment when not stripped and cleaned on a daily basis. While not without design flaws (a thin-diameter, fixed barrel that quickly overheated, limited magazine capacity, complex field-strip/cleaning procedure, unreliable recoil buffer mechanism, a gas cylinder assembly made of corrosion-prone metals, and many small internal parts), the BAR proved rugged and reliable enough when regularly field-stripped and cleaned.
During World War II, the BAR saw extensive service, both official and unofficial, with many branches of service. One of the BAR's most unusual uses was as a defensive aircraft weapon. In 1944, Captain Wally A. Gayda, of the USAAF Air Transport Command, reportedly used a BAR to return fire against a Japanese Army Nakajima fighter that had attacked his C-46 cargo plane over the Hump in Burma. Gayda shoved the rifle out his forward cabin window, emptying the magazine and apparently killing the Japanese pilot.
Korean War[edit | edit source]
The BAR continued in service in the Korean War. The last military contract for the manufacture of the M1918A2 was awarded to the Royal Typewriter Co. of Hartford, Connecticut, which manufactured a total of 61,000 M1918A2s during the conflict, using ArmaSteel cast receivers and trigger housings. In his study of infantry weapons in Korea, historian S.L.A. Marshall interviewed hundreds of officers and men in after-action reports on the effectiveness of various U.S. small arms in the conflict. General Marshall's report noted that an overwhelming majority of respondents praised the BAR and the utility of automatic fire delivered by a lightweight, portable small arm in both day and night engagements. A typical BAR gunner of the Korean War, one of which was named "Charles Phenix", carried the twelve-magazine belt and combat suspenders, with three or four extra magazines in pockets. Extra canteens, .45 pistol, grenades, and a flak vest added still more weight. As in World War II, many BAR gunners disposed of the heavy bipod and other accoutrements of the M1918A2, but unlike the prior conflict the flash hider was always retained because of its utility in night fighting.
The large amounts of ammunition expended by BAR teams in Korea placed additional demands on the assistant gunner to stay in close contact with the BAR at all times, particularly on patrols. While the BAR magazines themselves always seemed to be in short supply, Gen. Marshall reported that "riflemen in the squad were markedly willing to carry extra ammunition for the BAR man."
In combat, the M1918A2 frequently decided the outcome of frenzied attacks by North Korean and Chinese Communist forces. Communist tactical doctrine centered around the mortar and machine gun, with attacks designed to envelop and cut off United Nations forces from supply and reinforcement. Communist machine gun teams were the best-trained men in any given North Korean or Chinese infantry unit, skilled at placing their heavily camouflaged and protected weapons as close to U.N. forces as possible. Once concealed, they often surprised U.N. forces by opening fire at very short ranges, covering any exposed ground with a hail of accurately sighted machine gun fire. Under these conditions it was frequently impossible for U.S. machine gun crews to move up their Browning M1919A4 and M1919A6 guns in response without taking heavy casualties; when they were able to do so, their position was carefully noted by the enemy, who would frequently kill the exposed gun crews with mortar or machine gun fire while they were still emplacing their guns. The BAR gunner, who could stealthily approach the enemy gun position alone (and on his stomach if need be), proved invaluable in this type of combat.
During the height of combat, the BAR gunner was often used as the 'fire brigade' weapon, helping to bolster weak areas of the perimeter under heavy pressure by Communist forces. In the defense, it was often used to strengthen the firepower of a forward outpost. Another role for the BAR was to deter or eliminate enemy sniper fire. In the absence of a trained sniper, the BAR proved more effective than the random response of five or six M1 riflemen. Compared to World War II, U.S. infantry forces saw a huge increase in the number of night engagements. The added firepower of the BAR rifleman and his ability to redeploy to 'hot spots' around the unit perimeter proved indispensable in deterring night infiltration by skirmishers as well as repelling large-scale night infantry assaults. While new-production M1918A2 guns were almost universally praised for faultless performance in combat, a number of malfunctions in combat were reported with armory-reconditioned M1918A2s, particularly weapons that had been reconditioned by Ordnance in Japan, which did not replace operating (recoil) springs as a requirement of the reconditioning program. After decades of complaints Ordnance addressed the problem of maintaining the problematic gas piston on the BAR by issuing disposable nylon gas valves. When the nylon valve became caked over with carbon, it could be discarded and replaced with a fresh unit, eliminating the tedious task of cleaning and polishing the valve with wire brush and G.I. solvent (frequently in short supply to line units).
Vietnam War[edit | edit source]
The M1918A2 was used in the early stages of the Vietnam War, when the U.S. delivered a quantity of 'obsolete', second-line small arms to the South Vietnamese Army and associated allies, including the Montagnard hill tribespeople of South Vietnam. U.S. Special Forces advisors frequently chose the BAR over currently available infantry weapons. As one Special Forces sergeant declared, "Many times since my three tours of duty in Vietnam I have thanked God for . . . having a BAR that actually worked, as opposed to the jamming M16. . . We had a lot of Viet Cong infiltrators in all our [Special Forces] camps, who would steal weapons every chance they got. Needless to say, the most popular weapon to steal was the venerable old BAR."
Post-Vietnam use[edit | edit source]
Quantities of the BAR remained in use by the Army National Guard up until the mid-1970s. Many nations in NATO and recipients of U.S. foreign aid adopted the BAR and used it into the 1990s.
