M101 Howitzer
The M101A1 (previously designated Howitzer M2A2 on Carriage M2A2) howitzer is an artillery piece developed and used by the United States. It was the standard U.S. light field howitzer in World War II and saw action in both the European and Pacific theaters and during the Korean War. Entering production in 1941, it quickly gained a reputation for accuracy and a powerful punch. The M101A1 fires 105 mm high explosive (HE) semi-fixed ammunition and has a range of or 7 miles, making it suitable for supporting infantry. History Development and designation After World War I, the U.S. Army Ordnance Department studied various captured German 105 mm-caliber howitzers and developed the 105 mm Howitzer M1920 by using the Carriage M1920. A box trail carriage design (the M1925E carriage) and two other split trail designs (the T1 and T2) were also developed, but the original split trail design was found superior after testing. After being selected, the piece was standardized i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Howitzer
The howitzer () is an artillery weapon that falls between a cannon (or field gun) and a mortar. It is capable of both low angle fire like a field gun and high angle fire like a mortar, given the distinction between low and high angle fire breaks at 45 degrees or 800 mils (NATO). With their long-range capabilities, howitzers can be used to great effect in a battery formation with other artillery pieces, such as long-barreled guns, mortars, and rocket artillery. Howitzers were valued for their ability to fire explosive shells and incendiary materials into fortifications. Unlike mortars, which had fixed firing angles, howitzers could be fired at various angles, providing greater flexibility in combat. Throughout the 18th and 19th centuries, howitzers evolved to become more mobile and versatile. The introduction of rifling in the mid-19th century led to significant changes in howitzer design and usage. By the early 20th century, howitzers were classified into different categor ...

Russo-Ukrainian War
The Russo-Ukrainian War began in February 2014 and is ongoing. Following Ukraine's Revolution of Dignity, Russia Russian occupation of Crimea, occupied and Annexation of Crimea by the Russian Federation, annexed Crimea from Ukraine. It then supported Russian separatist forces in Ukraine, Russian paramilitaries who began a War in Donbas, war in the eastern Donbas region against Ukraine's military. In 2018, Ukraine declared the region to be Russian-occupied territories of Ukraine, occupied by Russia. These first eight years of conflict also included List of Black Sea incidents involving Russia and Ukraine, naval incidents and Russo-Ukrainian cyberwarfare, cyberwarfare. In February 2022, Russia launched a Russian invasion of Ukraine, full-scale invasion of Ukraine and began occupying more of the country, starting the biggest conflict in Europe since World War II. The war has resulted in a Ukrainian refugee crisis, refugee crisis and hundreds of thousands of deaths. In early 201 ...

Canon De 75 Modèle 1897
The French 75 mm field gun is a Quick-firing gun, quick-firing field artillery piece adopted in March 1898. Its official French designation was: Matériel de 75 mm Mle 1897. It was commonly known as the French 75, simply the 75 and Soixante-Quinze (French for "seventy-five"). The French 75 was designed as an anti-personnel weapon system for delivering large volumes of time-fused shrapnel shells on enemy troops advancing in the open. After 1915 and the onset of trench warfare, impact-detonated high-explosive shells prevailed. By 1918 the 75s became the main agents of delivery for Chemical warfare#Dispersion, toxic gas shells. The 75s also became widely used as truck mounted anti-aircraft artillery. They were the main armament of the Saint-Chamond (tank), Saint-Chamond tank in 1918 and the Char 2C. The French 75 is widely regarded as the first modern artillery piece.Priscilla Mary Roberts"French 75 gun" World War One, pg. 726 It was the first field gun to include a hyd ...

Infantry
Infantry, or infantryman are a type of soldier who specialize in ground combat, typically fighting dismounted. Historically the term was used to describe foot soldiers, i.e. those who march and fight on foot. In modern usage, the term broadly encompasses a wide variety of subspecialties, including light infantry, irregular infantry, heavy infantry, mountain infantry, motorized infantry, mechanized infantry, Airborne forces, airborne infantry, Air assault, air assault infantry, and Marines, naval infantry. Other subtypes of infantry, such as line infantry and mounted infantry, were once commonplace but fell out of favor in the 1800s with the invention of more accurate and powerful weapons. Etymology and terminology In English, use of the term ''infantry'' began about the 1570s, describing soldiers who march and fight on foot. The word derives from Middle French , from older Italian (also Spanish) ''infanteria'' (foot soldiers too inexperienced for cavalry), from Latin '' ...

Shell (projectile)
A shell, in a modern military context, is a projectile whose payload contains an explosive, incendiary device, incendiary, or other chemical filling. Originally it was called a bombshell, but "shell" has come to be unambiguous in a military context. A shell can hold a tracer ammunition, tracer. All explosive- and incendiary-filled projectiles, particularly for mortar (weapon), mortars, were originally called ''grenades'', derived from the French language, French word for pomegranate, so called because of the similarity of shape and that the multi-seeded fruit resembles the powder-filled, fragmentizing bomb. Words cognate with ''grenade'' are still used for an artillery or mortar projectile in some European languages. Shells are usually large-caliber projectiles fired by artillery, armored fighting vehicle, armoured fighting vehicles (e.g. tanks, assault guns, and mortar carriers), warships, and autocannons. The shape is usually a cylinder (geometry), cylinder topped by an o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Explosive Material
An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. The potential energy stored in an explosive material may, for example, be: * chemical energy, such as nitroglycerin or grain dust * pressurized gas, such as a gas cylinder, aerosol can, or boiling liquid expanding vapor explosion * nuclear energy, such as in the fissile isotopes uranium-235 and plutonium-239 Explosive materials may be categorized by the speed at which they expand. Materials that detonate (the front of the chemical reaction moves faster through the material than the speed of sound) are said to be "high explosives" and materials that deflagrate are sai ...

105 Mm
105 mm (4.1 in) is a common NATO-standard artillery and tank gun calibre. The rifled tank round is defined by STANAG 4458. The artillery round is defined by AOP-29 part 3 with reference to STANAG 4425. Artillery Since the early 21st century, most NATO armies have settled on 155 mm (6.1 in) weapons as having a good compromise between range and destructive power whilst having a single calibre, which simplifies logistics; however some military forces have retained 105 mm (4.1 in) towed howitzers for their lighter weight and greater portability, including their rapid airlift and airdrop capabilities. The lower power and shorter range of 105 mm (4.1 in) ammunition has led to its obsolescence in full-sized self-propelled guns, such as the American M108 howitzer and British FV433 Abbot SPG. China, North Korea, Russia, and other former Soviet bloc countries use 122 mm (4.8 in) and 130 mm (5.1 in) calibre weapons in similar roles. 105 mm artillery guns *FV433 Abbot SPG () *G7 howitzer ( ...

Pacific Ocean Theater Of World War II
The Pacific Ocean theater of World War II was a major theater of the Pacific War, the war between the Allies and the Empire of Japan. It included the U.S. Pacific Ocean Areas (command). which included most of the Pacific Ocean and its islands. The Philippines, the Dutch East Indies, Borneo, Australia, most of the Territory of New Guinea, and the western part of the Solomon Islands were under a different Allied command. History On March 30, 1942, US Admiral Chester Nimitz was appointed Commander-in-Chief, Pacific Ocean Areas. In the other major theater in the Pacific region, known as the South West Pacific theater, Allied forces were commanded by US General Douglas MacArthur. Both Nimitz and MacArthur were overseen by the US Joint Chiefs, and indirectly by the British-American Combined Chiefs of Staff. Most Japanese forces in the theater were part of the of the Imperial Japanese Navy (IJN), which was responsible for all Japanese warships, naval aircraft, and mar ...

European Theatre Of World War II
The European theatre of World War II was one of the two main theatres of combat during World War II, taking place from September 1939 to May 1945. The Allied powers (including the United Kingdom, the United States, the Soviet Union and France) fought the Axis powers (including Nazi Germany and Fascist Italy) on both sides of the continent in the Western and Eastern fronts. There was also conflict in the Scandinavian, Mediterranean and Balkan regions. It was an intense conflict that led to at least 39 million deaths and a dramatic change in the balance of power in the continent. During the 1930s, Adolf Hitler, the leader of Nazi Germany, expanded German territory by annexing all of Austria and the Sudetenland region of Czechoslovakia in 1938. This was motivated in part by Germany's racial policy that believed the country needed to expand for the pseudoscientific "Aryan race" to survive. They were aided by Italy, another fascist state which was led by Benito Mussolini. Wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Split Trail
A gun carriage is a frame or a mount that supports the gun barrel of an artillery piece, allowing it to be maneuvered and fired. These platforms often had wheels so that the artillery pieces could be moved more easily. Gun carriages are also used on ships to facilitate the movement and aiming of large cannons and guns. These are also used in the funeral procession of any higher authority of any state and country. Early guns The earliest guns were laid directly onto the ground, with earth being piled up under the muzzle end of the barrel to increase the elevation. As the size of guns increased, they began to be attached to heavy wooden frames or beds that were held down by stakes. These began to be replaced by wheeled carriages in the early 16th century. Smoothbore gun carriages From the 16th to the mid-19th century, the main form of artillery remained the smoothbore cannon. By this time, the trunnion (a short axle protruding from either side of the gun barrel) had been develo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Hydraulic Recoil Mechanism
A hydraulic recoil mechanism is a way of limiting the effects of recoil and adding to the accuracy and firepower of an artillery piece. Description The idea of using a water brake to counteract the recoil of naval cannons was first suggested to the British Admiralty by Carl Wilhelm Siemens in the early 1870s, but it took about a decade for the idea to be commercialized, primarily by Josiah Vavasseur. The usual recoil system in modern quick-firing guns is the ''hydro-pneumatic recoil system''. In this system, the barrel is mounted on rails on which it can recoil to the rear, and the recoil is taken up by a cylinder which is similar in operation to an automotive gas-charged shock absorber. It is commonly mounted parallel to the barrel, but is shorter and smaller. The cylinder is charged with compressed air, as well as hydraulic oil; in operation, the barrel's energy is taken up in compressing the air as the barrel recoils backward, then is dissipated via hydraulic da ...

Rifled Breech Loader
A rifled breech loader (RBL) is an artillery piece which, unlike the smoothbore cannon and rifled muzzle loader which preceded it, has rifling in the barrel and is loaded from the breech-loading weapon, breech at the rear of the gun. The spin imparted by the gun's rifling gives projectiles directional stability and increased range. Loading from the rear of the gun leaves the crew less exposed to enemy fire, allows smaller gun emplacements or turrets, and allows a faster rate of fire. These rapidly improving breech systems and the powerful new guns they facilitated led to an arms race in fortification and ironclad warship design that led to the battleship class of HMS Dreadnought (1906), HMS ''Dreadnought'' and continued until the start of World War I. Overview The major problem to be solved with breechloading artillery was obturation: the sealing of the breech after firing to ensure that none of the gases generated by the burning of the propellant (initially gunpowder) escaped r ...
