context_page_description: The Bren gun is a series of light machine guns made by Britain in the 1930s and used in various roles until 1992. While best known for its role as the British and Commonwealth forces' primary infantry LMG in World War II, it was also used in the Korean War and saw service throughout the latter half of the 20th century, including the 1982 Falklands War. Although fitted with a bipod, it could also be mounted on a tripod or be vehicle-mounted.
  The Bren gun was a licensed version of the Czechoslovak ZGB 33 light machine gun which, in turn, was a modified version of the ZB vz. 26, which British Army officials had tested during a firearms service competition in the 1930s. The later Bren gun featured a distinctive top-mounted curved box magazine, conical flash hider, and quick change barrel. The name Bren was derived from Brno, the Czechoslovak city in Moravia, where the Zb vz. 26 was designed and Enfield, site of the British Royal Small Arms Factory. The designer was Václav Holek, a gun inventor and design engineer.
  In the 1950s, many Bren guns were re-barrelled to accept the 7.62×51mm NATO cartridge and modified to feed from the magazine for the L1 rifle as the L4 light machine gun.
context_section_description: In the British and Commonwealth armies, the Bren was generally issued on a scale of one per rifle section. An infantry battalion also had a "carrier" platoon, equipped with Universal Carriers, each of which carried a Bren gun. Parachute battalions from 1944 had an extra Bren in the AT platoon. The 66-man "Assault Troop" of British Commandos had a nominal establishment of four Bren guns. Realising the need for additional section-level firepower, the British Army endeavoured to issue the Bren in great numbers, with a stated goal of one Bren to every four private soldiers. The Bren was operated by a two-man crew, sometimes commanded by a Lance Corporal as an infantry section's "gun group", the remainder of the section forming the "rifle group". The gunner or "Number 1" carried and fired the Bren, and a loader or "Number 2" carried extra magazines, a spare barrel and a tool kit. Number 2 helped reload the gun and replace the barrel when it overheated, and spotted targets for Number 1.
  Generally, the Bren was fired from the prone position using the attached bipod. On occasion, a Bren gunner would use his weapon on the move supported by a sling, much like an automatic rifle, and from standing or kneeling positions. Using the sling, Australian soldiers regularly fired the Bren from the hip, for instance in the marching fire tactic, a form of suppressive fire moving forward in assault. A Victoria Cross was awarded to Private Bruce Kingsbury for such use at Isurava, New Guinea, in 1942, during the Australians' fighting retreat from Kokoda.
  Each British soldier's equipment normally included two magazines for his section's Bren gun. The large ammunition pouches on the 1937 Pattern Web Equipment were designed around the Bren magazine. Every soldier would be trained to fire the Bren in case of an emergency, though these soldiers did not receive a Bren proficiency badge.
  The Bren had an effective range of around 600 yards (550 m) when fired from a prone position with a bipod.
  For a light machine gun of the interwar and early World War II era, the Bren was about average in weight. On long marches in non-operational areas it was often partially disassembled and its parts were carried by two soldiers. The top-mounted magazine vibrated and moved during fire, making the weapon more visible in combat, and many Bren gunners used paint or improvised canvas covers to disguise the prominent magazine.
  The 30-round magazine was in practice usually filled with 27 or 28 rounds to prevent jams and avoid wearing out the magazine spring. Care needed to be taken when loading the magazine to ensure that each round went ahead of the previous round, so that the .303 cartridge rims did not overlap the wrong way, which would cause a jam. The spent cartridge cases were ejected downwards, which was an improvement on the Lewis gun, which ejected sideways, since the glint of them flying through the air could compromise a concealed firing position.
  In general, the Bren was considered a reliable and effective light machine gun, though in North Africa it was reported to jam regularly unless kept very clean and free of sand or dirt. It was popular with British troops, who respected its reliability and combat effectiveness. The quality of the materials used would generally ensure minimal jamming. When the gun did jam through fouling caused by prolonged firing, the operator could adjust the four-position gas regulator to feed more gas to the piston increasing the power to operate the mechanism. The barrel needed to be unlocked and slid forward slightly to allow the regulator to be turned. It was even said that all problems with the Bren could simply be cleared by hitting the gun, turning the regulator or doing both. It was "by general consent the finest light machine gun in the world of its period, and the most useful weapon provided to the (French) "maquis" ... accurate up to 1,000 meters, and (it) could withstand immense maltreatment and unskilled use. "Resistants" were constantly pleading for maximum drops of Brens".
