United States Hand Grenades
The military of the United States has used many different types of hand grenades since its foundation. High explosive, fragmentation, and blast Mk I The Mk 1 grenade was introduced in 1917 during World War I. A multistep arming process on the device resulted in many failures, and as a result it was replaced in 1918 by the Mk II. Mk II and Mk IIA1 More commonly known as the ''Pineapple'', the Mk II series (also written Mk 2) was the most commonly used US fragmentation grenade of the Second World War. The Mk II had a grooved exterior originally intended to aid fragmentation of the grenade. However, later studies showed that this design has no effect on fragmentation, though it does provide a non-slip surface that improves grip. The filling was either EC blank fire powder (approximately . smokeless small arms powder) or flaked TNT (approx. ). TNT became the common filler from 1942 onwards.Vilinsky, Alan.

Vietnam War
The Vietnam War (1 November 1955 – 30 April 1975) was an armed conflict in Vietnam, Laos, and Cambodia fought between North Vietnam (Democratic Republic of Vietnam) and South Vietnam (Republic of Vietnam) and their allies. North Vietnam was supported by the Soviet Union and China, while South Vietnam was supported by the United States and other anti-communist nations. The conflict was the second of the Indochina wars and a proxy war of the Cold War between the Soviet Union and US. The Vietnam War was one of the postcolonial wars of national liberation, a theater in the Cold War, and a civil war, with civil warfare a defining feature from the outset. Direct United States in the Vietnam War, US military involvement escalated from 1965 until its withdrawal in 1973. The fighting spilled into the Laotian Civil War, Laotian and Cambodian Civil Wars, which ended with all three countries becoming Communism, communist in 1975.

North Vietnam w ... and was also used during the First Gulf War. The M34 WP Grenade replaced the World War II M15 WP grenade. The M34 could be fired from a rifle grenade launcher using M2-series grenade launching adapters due to the groove around the tapered base, which allowed the adapter arms to grasp it. In contrast, the M15 could not be fired as a rifle grenade. The M34 had a segmented body to allow for a better hand grip and to identify it as a casualty-producing grenade, even though fragmentation was not its primary damage mechanism. The smooth-bodied ...

White Phosphorus
White phosphorus, yellow phosphorus, or simply tetraphosphorus (P4) is an allotrope of phosphorus. It is a translucent waxy solid that quickly yellows in light (due to its photochemical conversion into red phosphorus), and impure white phosphorus is for this reason called yellow phosphorus. White phosphorus is the first allotrope of phosphorus, and in fact the first elementary substance to be discovered that was not known since ancient times. It glows greenish in the dark (when exposed to oxygen) and is highly flammable and pyrophoric (self-igniting) upon contact with air. It is toxic, causing severe liver damage on ingestion and phossy jaw from chronic ingestion or inhalation. The odour of combustion of this form has a characteristic garlic odor, and samples are commonly coated with white " diphosphorus pentoxide", which consists of tetrahedra with oxygen inserted between the phosphorus atoms and at their vertices. White phosphorus is only slightly soluble in water and can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Navy SEALs
The United States Navy Sea, Air, and Land (SEAL) Teams, commonly known as Navy SEALs, are the United States Navy's primary special operations force and a component of the United States Naval Special Warfare Command. Among the SEALs' main functions are conducting small-unit special operation missions in maritime, jungle, urban, arctic, mountainous, and desert environments. SEALs are typically ordered to capture or kill high-level targets, or to gather intelligence behind enemy lines. SEAL team personnel are hand-selected, highly trained, and highly proficient in unconventional warfare (UW), direct action (DA), and special reconnaissance (SR), among other tasks like sabotage, demolition, intelligence gathering, and hydrographic reconnaissance, training, and advising friendly militaries or other forces. All active SEALs are members of the U.S. Navy. History Origins Although not formally founded until 1962, the modern-day U.S. Navy SEALs trace their roots to World War II. The U ...

Terephthalic Acid
Terephthalic acid is an organic compound with formula C6H4(CO2H)2. This white solid is a commodity chemical, used principally as a precursor to the polyester PET, used to make clothing and plastic bottles. Several million tons are produced annually. The common name is derived from the turpentine-producing tree ''Pistacia terebinthus'' and phthalic acid. Terephthalic acid is also used in the production of PBT plastic (polybutylene terephthalate). History Terephthalic acid was first isolated (from turpentine) by the French chemist Amédée Cailliot (1805–1884) in 1846. Terephthalic acid became industrially important after World War II. Terephthalic acid was produced by oxidation of ''p''-xylene with 30-40% nitric acid. Air oxidation of ''p''-xylene gives ''p''-toluic acid, which resists further air-oxidation. Esterification of ''p''-toluic acid to methyl p-toluate (CH3C6H4CO2CH3) opens the way for further oxidation to monomethyl terephthalate. In the Dynamit−Nobel process t ...

Hexachloroethane
Hexachloroethane (perchloroethane) is an organochlorine compound with the chemical formula . Its structure is . It is a white or colorless solid at room temperature with a camphor-like odor. It has been used by the military in smoke compositions, such as base-eject smoke munitions ( smoke grenades). Hexachloroethane was discovered along with carbon tetrachloride by Michael Faraday in 1820. Faraday obtained it by chlorinating ethylene. Manufacture Chlorination of tetrachloroethylene at 100–140 °C with the presence of iron(III) chloride is the most commonly used commercial production method, however several other methods exist. A high purity form can be produced in a small scale by reacting chlorine together with barium carbide. In September 1997, it was reported as no longer being produced in the United States for commercial distribution, but was produced as a by-product of industrial chlorination process. : Applications Hexachloroethane has been used in the formulation ...

AN M8
The AN-M8 HC Smoke Grenade designated as the Army/Navy Model 8 HC Smoke Grenade (AN-M8 Smoke HC) is a US military grenade used as a ground-to-ground obscuring or screening device or a ground-to-air signaling or target-marking device. History Developed in the 1940s, using a sheet-steel cylinder body that can emit a dense cloud of white smoke that would last from 105 to 150 seconds. The AN-M8 was used extensively by American or other allied forces throughout World War II to the 1990s. As of the September 2000 version of FM 3-23.30 ''Grenades and Pyrotechnic Signals'', the AN/M8 was listed as obsolete. Details It is used for smoke screening, target marking, and signalling, although the M18 colored smoke grenades are mainly used for the latter. Warning #The AN-M8 hand grenade produces harmful hydrochloric fumes that irritate the eyes, throat, and lungs. It should not be used in closed-in areas unless the users are wearing protective masks. #Both the AN-M8 and the M18 risk st ...
