Mills Grenade
"Mills bomb" is the popular name for a series of British hand grenades which were designed by William Mills (inventor), William Mills. They were the first modern fragmentation grenades used by the British Army and saw widespread use in the First World War, First and Second World Wars. Development William Mills (inventor), William Mills, a hand grenade designer from Sunderland, Tyne and Wear, Sunderland, patented, developed and manufactured the "Mills bomb" at the Mills Munitions Factory in Birmingham, England, in 1915. The Mills bomb was inspired by an earlier design by Belgian captain Leon Roland, who later engaged in a patent lawsuit. Col. Arthur Morrow, a New Zealand Wars officer, also believed aspects of his patent were incorporated into the Mills Bomb. The Mills bomb was adopted by the British Army as its standard hand grenade in 1915 as the No. 5. The Mills bomb underwent numerous modifications. The No. 23 was a No. 5 with a rodded base plug which allowed it to be fired ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hand Grenade
A grenade is a small explosive weapon typically thrown by hand (also called hand grenade), but can also refer to a Shell (projectile), shell (explosive projectile) shot from the muzzle of a rifle (as a rifle grenade) or a grenade launcher. A modern hand grenade generally consists of an explosive charge ("filler"), a detonator mechanism, an internal Firing pin, striker to trigger the detonator, an arming safety secured by a transport safety. The user removes the transport safety before throwing, and once the grenade leaves the hand the arming safety gets released, allowing the striker to trigger a Percussion cap, primer that ignites a fuze (sometimes called the delay element), which burns down to the detonator and explodes the main charge. Grenades work by dispersing fragments (fragmentation grenades), shockwaves (High explosive, high-explosive, Anti-tank grenade, anti-tank and stun grenades), chemical aerosols (Smoke grenade, smoke, Grenade#Chemical and gas, gas and Grenade#Chemi ...

Blast Injury
A blast injury is a complex type of physical trauma resulting from direct or indirect exposure to an explosion. Blast injuries occur with the detonation of high-order explosives as well as the deflagration of low order explosives. These injuries are compounded when the explosion occurs in a confined space. Classification Blast injuries are divided into four classes: primary, secondary, tertiary, and quaternary. Primary injuries Primary injuries are caused by blast overpressure waves, or shock waves. Total body disruption is the most severe and invariably fatal primary injury. Primary injuries are especially likely when a person is close to an exploding munition, such as a land mine. The ears are most often affected by the overpressure, followed by the lungs and the hollow organs of the gastrointestinal tract. Gastrointestinal injuries may present after a delay of hours or even days. Injury from blast overpressure is a pressure and time dependent function. By increasing the p ...

Lee–Enfield
The Lee–Enfield is a bolt-action, magazine-fed repeating rifle that served as the main firearm of the military forces of the British Empire and Commonwealth during the first half of the 20th century, and was the standard service rifle of the British Armed Forces from its official adoption in 1895 until 1957. A redesign of the Lee–Metford (adopted by the British Army in 1888), the Lee–Enfield superseded it and the earlier Martini–Henry and Martini–Enfield rifles. It featured a ten-round box magazine which was loaded with the .303 British cartridge manually from the top, either one round at a time or by means of five-round chargers. The Lee–Enfield was the standard-issue weapon to rifle companies of the British Army, colonial armies (such as India and parts of Africa), and other Commonwealth nations in both the First and Second World Wars (such as Australia, New Zealand, South Africa, and Canada). Although officially replaced in the United Kingdom with the L1A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rifle Grenade
A rifle grenade is a grenade that uses a rifle-based launcher to permit a longer effective range than would be possible if the grenade were thrown by hand. The practice of projecting grenades with rifle-mounted launchers was first widely used during World War I and World War II and continues to the present, with the term "rifle grenade" now encompassing many different types of payloads including high explosive, fragmentation, anti-tank warheads, concussion, smoke, incendiary, and flare missiles. Rifle grenades have largely been supplanted in the infantry fire support role by a combination of grenade launchers (typically affixed to rifles) and disposable anti-armor rockets. History Early use Adaptation of grenades for use in rifles began around the 18th century, when cup-shaped dischargers were fitted to the barrels of flintlock muskets, with the grenades propelled by the force of a blank cartridge. During the early 20th century a Japanese Colonel Amazawa experimented w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ammonal
Ammonal is an explosive made up of ammonium nitrate and aluminium powder. TNT is added to create T-ammonal which improves properties such as brisance. The mixture is often referred to as Tannerite, which is a brand of ammonal. The ammonium nitrate functions as an oxidizer and the aluminium as fuel. The use of the relatively cheap ammonium nitrate and aluminium makes it a replacement for pure TNT. The mixture is affected by humidity because ammonium nitrate is highly hygroscopic. Ammonal's ease of detonation depends on fuel and oxidizer ratios, 95:5 ammonium nitrate and aluminium being fairly sensitive, however not very oxygen balanced. Even copper metal traces are known to sensitize bulk amounts of ammonium nitrate and further increase danger of spontaneous detonation during a fire, most likely due to the formation of tetramines. More oxygen balanced mixtures are not easily detonated, requiring a fairly substantial shock, though it remains more sensitive than trinitrotolue ...

Trotyl
Troponin T (shortened TnT or TropT) is a part of the troponin complex, which are proteins integral to the contraction of skeletal and heart muscles. They are expressed in skeletal and cardiac myocytes. Troponin T binds to tropomyosin and helps position it on actin, and together with the rest of the troponin complex, modulates contraction of striated muscle. The cardiac subtype of troponin T is especially useful in the laboratory diagnosis of heart attack because it is released into the blood-stream when damage to heart muscle occurs. It was discovered by the German physician Hugo A. Katus at the University of Heidelberg, who also developed the troponin T assay. Subtypes * Slow skeletal troponin T1, TNNT1 (19q13.4, ) * Cardiac troponin T2, TNNT2 (1q32, ) * Fast skeletal troponin T3, TNNT3 (11p15.5, ) Reference values The 99th percentile cutoff for cardiac troponin T (cTnT) is 0.01 ng/mL. The reference range for the high sensitivity troponin T is a normal 52 ng/L. Backgroun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baratol
Baratol is an explosive made of a mixture of TNT and barium nitrate, with a small quantity (about 1%) of paraffin wax used as a phlegmatizing agent. TNT typically makes up 25% to 33% of the mixture. Because of the high density of barium nitrate, Baratol has a density of at least 2.5 g/cm3. Baratol, which has a detonation velocity of only about 4,900 metres per second, was used as the slow-detonating explosive in the explosive lenses of some early atomic bomb designs, with Composition B often used as the fast-detonating component. Atomic bombs detonated at Trinity in 1945, the Soviet Joe 1 in 1949, and in India in 1972 all used Baratol and Composition B. Baratol was also used in the Mills bomb, a British hand grenade A grenade is a small explosive weapon typically thrown by hand (also called hand grenade), but can also refer to a Shell (projectile), shell (explosive projectile) shot from the muzzle of a rifle (as a rifle grenade) or a grenade launcher.

Amatol
Amatol is a highly explosive material made from a mixture of TNT and ammonium nitrate. The British name originates from the words ammonium and toluene (the precursor of TNT). Similar mixtures (one part dinitronaphthalene and seven parts ammonium nitrate) were known as Schneiderite in France. Amatol was used extensively during World War I and World War II, typically as an explosive in military weapons such as aircraft bombs, shells, depth charges, and naval mines.Brown, G. I. (1998). ''The Big Bang: A History of Explosives''. Sutton Publishing . pp. 158-163. It was eventually replaced with alternative explosives such as Composition B, Torpex, and Tritonal. Invention Following the Shell Crisis of 1915 in which the UK did not have enough ordnance due to a lack of explosives, a team at the Royal Arsenal laboratories produced a mixture of ammonium nitrate and TNT, known as Amatol for short. Special factories were constructed for the manufacture of ammonium nitrate by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mesopotamian Campaign
The Mesopotamian campaign or Mesopotamian front () was a campaign in the Middle Eastern theatre of World War I fought between the British Empire, with troops from United Kingdom of Great Britain and Ireland, Britain, Australia and the vast majority from the British Raj, against the Central Powers, mostly the Ottoman Empire. It started after the British Fao Landing in 1914, which sought to protect Anglo-Persian Oil Company oil fields in Khuzestan province and the Shatt al-Arab waterway. The front later evolved into a larger campaign that sought to capture the city of Baghdad and divert Ottoman forces from other fronts. It ended with the Armistice of Mudros in 1918, leading to the cession of Iraq (then Mesopotamia) and further partition of the Ottoman Empire. The British advanced from Al-Faw to the city of Basra to secure British oil fields in nearby Qajar Iran, Iran. Following the landings, British forces won a string of victories along the Tigris and Euphrates rivers, including t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jason Dunham
Jason Lee Dunham (November 10, 1981 – April 22, 2004) was a corporal in the United States Marine Corps who was posthumously awarded the Medal of Honor for his actions while serving with 3rd Battalion 7th Marines during the Iraq War. While on a patrol in Husaybah, his unit was attacked. In the course of the fighting, Dunham deliberately used his helmet and body to cover a live grenade and save nearby Marines. When it exploded Dunham was gravely injured and died eight days later. Early life and education Jason Dunham was born on November 10, 1981, in Scio, New York, and resided there with his parents, Dan and Deb, and his three siblings, two brothers and a sister.

M61 Grenade
The M26 is a fragmentation hand grenade developed by the United States military. It entered service in 1952 and was first used in combat during the Korean War, replacing the Mk 2 of World War II. The M26 series was the primary fragmentation grenade used by American forces in the Vietnam War. It was replaced by the M33 series grenade. Its distinct lemon shape led it to being nicknamed the "lemon grenade" (compare the Russian F1 and American Mk 2 "pineapple" grenades). History The M26 series was created after World War II to meet criticisms of the Mk 2. Rather than relying on a cast body to produce fragments like the Mk 2 the M26 had a thin sheet-metal body and the fragments were instead created by a notched wire coiled up inside which produced smaller fragments but a greater number traveling at a higher velocity and distributed them more evenly than the Mk 2, giving it a larger effective casualty producing radius. The fragments were also more consistently sized posing less o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
