The Browning Automatic Rifle was designed by the famous American arms designer John Moses Browning late in the First World War, on the request from USExpeditionary corps in Europe. Initially it was just like that - the Automatic Rifle, a selective fire weapon, intended for use by infantry men to fire from the shoulder or from the hip when advancing onto the enemy positions, and to provide mobile firepower to every squad, since the standard machine guns were heavy and much less maneuverable. But the BAR M1918 was way too heavy for a shoulder fired weapon, being more that 2 times heavier than a bolt-action SpringfieldM1903 rifle and exactly 2 times heavier than a latter M1Garand semiautomatic rifle. On the other hand, it was too light to be controllable in full automatic mode, especially when firing such a powerful round from a shouldered unsupported position. Anyway, the M1918, made by theColt Firearms co. were issued to some US troops by the end of the war. After the war, the development of the BAR continued. In 1922, US Cavalry adopted the M1922light machine gun, which featured a folding bipod under the partially ribbed barrel, a removable monopod ("third leg") under the butt, and a M1917machine gun sights. The Colt company also produced a lightened semi-automatic version of the BAR, called a Colt model 75 "Monitor" rifle. This wasintended mostly for police use, but also found its way into the hands of outlaws, too.
During the 1930s, next version of the BAR, designated as M1918A1, was briefly manufactured. This gun featured skid-footed folding bipods, attached to the gasblock. The butt was fitted with hinged steel buttplate.
In 1939, the final American version of the BAR appeared, under the designation of M1918A2. This version, manufactured by Colt, Marlin-Rockwell, and Winchester,served in the Squad Automatic Weapon role with US troops during the 2nd World War and latter Korea War. Many of earlier M1918A1 guns were converted to the M1918A2 configuration, which featured skid-footed adjustable bipod under the flash hider,M1917 sights, smaller forend and metal heat shield between barrel and cylinder/spring, single shots replaced bytwo selectable full auto modes, with fast (~650 rpm) and slow (~450 rpm) ratesof fire. The bipod, however, was somewhat awkward, uncomfortable and heavy, somany M1918A2 were used with bipod removed.
Technical description.
The BAR M1918 is a gas operated, magazine fed, air cooled weapon. It used the gas piston, located under the barrel, and the bolt with tilting locking lug,that was raised to lock into the roof of the receiver. This lug was linked to the operating rod via the swinging link, much like in the earlier Berthiersystem. The BAR always fired from the open bolt to avoid cook-offs. The return spring was located around the gas piston under the barrel, so it was prone tooverheating and lost its temper during the prolonged fire sessions, resulting in jams and stoppages. This issue was somewhat cured in M1918A1 with introductionof the heat shield between the barrel and the spring, located inside the for end.
The receiver was a machined piece of steel, and the un was fed from the detachable 20 rounds box magazines. Barrel was fitted with flash hiders of different types, and, since the M1818A1, the wooden buttstock was also fitted with the hinged buttplate. The latter production models of M1918A2 were alsofitted with carrying handle.
The buttstocks and for ends were mostly made from wood, but on late production M1918A2's sometimes were also made from plastics.
The BAR was the core weapon of the Marine rifle squad. Marine Corps doctrine stressed that fire team leaders should keep direct control of their BAR men. The squad leader was charged with designating BAR positions on the defense, and organizing the other fighting positions around them. Marines respected the firepower of the BAR, and it earned a reputation as a reliable weapon that could not be broken. There was no sound that reassured Marines more than the steady hammer of the BAR firing in a tight spot.
Of course, the BAR had its drawbacks too. First, it was downright heavy–the weapon with its 12 loaded magazines weighed almost 40 pounds. That was a lot to carry for a kid who might only weigh 140 pounds himself.
There was no provision to change the barrel after rapid firing, so the BAR got really hot. After firing a few hundred rounds in a short period, the barrel would glow red, and the heat scorched the wooden fore end beneath the barrel. And it flat out burned through ammo. Marines learned to fire in 3 to 5 round bursts, but that was still only four trigger pulls for a magazine. It took much longer to load a BAR magazine than to fire it.
Among the many heroic Marines of World War II was Pfc Paul Witek, of Chicago, Ill. Pfc Witek was a BAR man in 1st Battalion, 9th Marines, 3rd Marine Division during the campaign for Guam. During the battle for Finegayan on 3 August 1944, his platoon was pinned down by heavy fire. Pfc Witek covered his fellow Marines by firing a full magazine from his BAR while standing erect.
While his platoon withdrew to reconsolidate, Pfc Witek remained to cover one of his wounded buddies waiting for evacuation. Hit by enemy machine gun fire again and pinned down, the platoon took cover and Pfc Witek unhesitatingly moved forward, throwing hand grenades and firing bursts from his BAR. He closed to within 5 to 10 yards of the enemy position, destroying the emplacement and killing eight Japanese soldiers. He was struck and killed by enemy rifle fire. For his heroic and sacrificial actions, Pfc Witek was awarded a posthumous Medal of Honor.
Even with its drawbacks, the BAR was one of the best squad automatic weapons in World War II. By war's end, there were 27 BARs in every Marine rifle company.
