Heavy Machine-gun
A heavy machine gun (HMG) is significantly larger than light, medium or general-purpose machine guns. HMGs are typically too heavy to be man-portable (carried by one person) and require mounting onto a weapons platform to be operably stable or tactically mobile, have more formidable firepower, and generally require a team of personnel for operation and maintenance. There are two generally recognized classes of weapons identified as HMGs. The first are weapons from World War I identified as "heavy" due to the weight and cumbersomeness of the weapons themselves, which prevents infantrymen from transporting on foot, such as the M1917 Browning machine gun. The second are large-caliber (12.7×99mm, 12.7×108mm, 14.5×114mm, or larger) machine guns, pioneered by John Browning with the M2 machine gun, designed to provide increased effective range, penetration and destructive power against covers, vehicles, aircraft and light buildings/fortifications beyond the standard-caliber rif ...

M2 Machine Gun
The M2 machine gun or Browning .50 caliber machine gun (informally, "Ma Deuce") is a heavy machine gun that was designed towards the end of World War I by John Browning. Its design is similar to Browning's earlier M1919 Browning machine gun, which was chambered for the .30-06 cartridge. The M2 uses Browning's larger and more powerful .50 BMG (12.7 mm) cartridge. The design has had many designations; the official U.S. military designation for the current infantry type is Browning Machine Gun, Cal. .50, M2, HB, Flexible. It is effective against infantry, unarmored or lightly armored vehicles and boats, light fortifications, and low-flying aircraft. The gun has been used extensively as a vehicle weapon and for aircraft armament by the United States since the 1930s. It was heavily used during World War II, the Korean War, the Vietnam War, the Falklands War, the Soviet–Afghan War, the Gulf War, the Iraq War, and the War in Afghanistan. It is the primary heavy machine gun of NATO ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Fortification
A fortification is a military construction or building designed for the defense of territories in warfare, and is also used to establish rule in a region during peacetime. The term is derived from Latin ''fortis'' ("strong") and ''facere'' ("to make"). From very early history to modern times, defensive walls have often been necessary for cities to survive in an ever-changing world of invasion and conquest. Some settlements in the Indus Valley civilization were the first small cities to be fortified. In ancient Greece, large stone walls had been built in Mycenaean Greece, such as the ancient site of Mycenae (famous for the huge stone blocks of its 'cyclopean' walls). A Greek '' phrourion'' was a fortified collection of buildings used as a military garrison, and is the equivalent of the Roman castellum or English fortress. These constructions mainly served the purpose of a watch tower, to guard certain roads, passes, and borders. Though smaller than a real fortress, they act ...

A Soldier With The Ukrainian Land Forces Fires A Degtyaryov-Shpagin Large-Caliber Heavy Machine Gun
A, or a, is the first letter and the first vowel of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version can be written in two forms: the double-storey a and single-storey ɑ. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English grammar, " a", and its variant " an", are indefinite articles. History The earliest certain ancestor of "A" is aleph (also written 'aleph), the first letter of the Phoenician alphabet, which consisted entirely of consonants (for that reason, it is also called an abjad to distinguish it fr ...

Russian M1910 Maxim
The Pulemyot Maxima PM1910 (PM M1910) (Russian: Пулемёт Максима образца 1910 года, ''Pulemyot Maxima obraztsa 1910 goda'' – "Maxim's machine gun Model 1910") is a Heavy machine gun that was used by the Imperial Russian Army during World War I and the Red Army during the Russian Civil War and World War II. Later the gun saw service in the Korean War, the Vietnam War and the 2022 Russian invasion of Ukraine. History It was adopted in August 1910 and was derived from Hiram Maxim's Maxim gun, chambered for the standard Russian 7.62×54mmR rifle cartridge. The M1910 was mounted on a wheeled mount with a gun shield. In 1918–1920, the industry of Soviet Russia produced 21 thousand new Maxim 1910 machine guns for the Red Army.Пулемёты // Гражданская война и военная интервенция в СССР.

Vickers Machine Gun
The Vickers machine gun or Vickers gun is a Water cooling, water-cooled .303 British (7.7 mm) machine gun produced by Vickers Limited, originally for the British Army. The gun was operated by a three-man crew but typically required more men to move and operate it: one fired, one fed the ammunition, the others helped to carry the weapon, its ammunition, and spare parts. It was in service from before the First World War until the 1960s, with air-cooled versions of it on many Allies of World War I, Allied World War I fighter aircraft. The weapon had a reputation for great solidity and reliability. Ian V. Hogg, in ''Weapons & War Machines'', describes an action that took place in August 1916, during which the British 100th Company of the Machine Gun Corps fired their ten Vickers guns to deliver sustained fire for twelve hours. Using 100 barrels, they fired a million rounds without breakdowns. "It was this absolute foolproof reliability which endeared the Vickers to every Britis ...

MG 08
The ''Maschinengewehr'' 08, or MG 08, was the German Army's standard machine gun in World War I and is an adaptation of Hiram S. Maxim's original 1884 Maxim gun. It was produced in a number of variants during the war. The MG 08 served during World War II as a heavy machine gun in many German infantry divisions, although by the end of the war it had mostly been relegated to second-rate fortress units. The ''Maschinengewehr'' 08 (or MG 08)—so-named after 1908, its year of adoption—was a development of the license made ''Maschinengewehr'' 01. The firing rate depends on the lock assembly used and averages 500 rounds per minute for the Schloss 08 and 600 rounds per minute for the Schloss 16. The gun used 250-round fabric belts of 7.92×57mm ammunition. It was water-cooled, using a jacket around the barrel that held approximately of water. Using a separate attachment sight with range calculator for indirect fire, the MG 08 could be operated from cover. Additional telescopic sigh ...

Hiram Maxim
Sir Hiram Stevens Maxim (5 February 1840 – 24 November 1916) was an American-British inventor best known as the creator of the first automatic machine gun, the Maxim gun. Maxim held patents on numerous mechanical devices such as hair-curling irons, a mousetrap, and steam pumps. Maxim laid claim to inventing the lightbulb. Maxim experimented with powered flight; his large aircraft designs were never successful. He designed a highly successful amusement ride called the "Captive Flying Machine" to fund his research while generating public interest in flight. Maxim moved from the United States to the United Kingdom at the age of 41, and remained an American citizen until he became a naturalised British subject in 1899, and received a knighthood in 1901. Birth and early life Maxim was born in Sangerville, Maine on 5 February 1840. He became an apprentice coachbuilder at the age of 14 and ten years later, took up a job at the machine works of his uncle, Levi Stephens, at ...

Maxim Gun
The Maxim gun is a recoil-operated machine gun invented in 1884 by Hiram Stevens Maxim. It was the first fully automatic machine gun in the world. The Maxim gun has been called "the weapon most associated with imperial conquest" by historian Martin Gilbert, and was heavily used by colonial powers during the "Scramble for Africa". Afterwards, Maxim guns also saw extensive usage by different armies during the Russo-Japanese War, the First and Second World Wars, as well as by insurgent groups in contemporary conflicts. The Maxim gun was greatly influential in the development of machine guns, and it has multiple variants and derivatives. Design The Maxim gun featured one of the earliest recoil-operated firing systems in history. Energy from recoil acting on the breech block is used to eject each spent cartridge and insert the next one. Maxim's earliest designs used a 360-degree rotating cam to reverse the movement of the block, but this was later simplified to a toggle lock. T ...

303 British
The .303 British (designated as the 303 British by the C.I.P. and SAAMI) or 7.7×56mmR, is a calibre rimmed rifle cartridge. The .303 inch bore diameter is measured between rifling lands as is the common practice in Europe which follows the traditional black powder convention. It was first manufactured in Britain as a stop-gap black powder round put into service in December 1888 for the Lee–Metford rifle. From 1891 the cartridge used smokeless powder which had been the intention from the outset, but the decision on which smokeless powder to adopt had been delayed. It was the standard British and Commonwealth military cartridge for rifles and machine guns from 1889 until the 1950s when it was replaced by the 7.62×51mm NATO. Cartridge specifications The .303 British has 3.64 ml (56 grains H2O) cartridge case capacity. The pronounced tapering exterior shape of the case was designed to promote reliable case feeding and extraction in bolt-action rifles and machine guns a ...

Recoil
Recoil (often called knockback, kickback or simply kick) is the rearward thrust generated when a gun is being discharged. In technical terms, the recoil is a result of conservation of momentum, as according to Newton's third law the force required to accelerate something will evoke an equal but opposite reactional force, which means the forward momentum gained by the projectile and exhaust gases (ejectae) will be mathematically balanced out by an equal and opposite momentum exerted back upon the gun. In hand-held small arms, the recoil momentum will be eventually transferred to the ground, but will do so through the body of the shooter hence resulting in a noticeable impulse commonly referred to as a "kick". In heavier mounted guns, such as heavy machine guns or artillery pieces, recoil momentum is transferred to the Earth's surface through the platform on which the weapon is mounted. In order to bring the rearward moving gun to a halt, the momentum acquired by the gun is di ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Squad Automatic Weapon
A squad automatic weapon (SAW), also known as a section automatic weapon or light support weapon (LSW), is a man-portable automatic firearm attached to infantry squads or sections as a source of rapid direct firepower. Weapons fulfilling this role can be light machine guns, or modified selective-fire rifles fitted with a heavier barrel, bipod and a belt/drum-fed design. Squad automatic weapons usually fire the same cartridge (though heavier-bullet variants are preferred) as the assault rifles or battle rifles carried by other members of the unit. This reduces logistical requirements by making it only necessary to supply one type of service ammunition to a unit. These weapons are light enough to be carried and operated by one infantryman, unlike medium machine guns (such as the M1919 Browning) that require a crew to operate at full effectiveness; or heavy machine guns (such as the M2 Browning or the DShK) which fire more powerful cartridges but are also crew-served and typica ...
