M202A1
The M202 FLASH ("Flame Assault Shoulder") is an American rocket launcher manufactured by Northrop Corporation, designed to replace the World War II–vintage flamethrowers (such as the M1 and the M2) that remained the military's standard incendiary devices well into the 1980s. The XM202 prototype launcher was tested in the Vietnam War, as part of the XM191 system. Description The M202A1 features four tubes that can load 66 mm incendiary rockets. The M-74 rockets are equipped with M235 warheads, containing approximately 1.34 pounds (610 g) of an incendiary agent. The substance, often mistaken for napalm , is in fact TPA (thickened pyrophoric agent). TPA is triethylaluminum (TEA) thickened with polyisobutylene, in the presence of n-hexane, preventing spontaneous combustion after the warhead rupture. TEA, an organometallic compound, is pyrophoric and burns spontaneously at temperatures of 1600 °C (2912 °F) when exposed to air. It burns "white hot" becaus ...

Triethylaluminum
Triethylaluminium is one of the simplest examples of an organoaluminium compound. Despite its name it has the formula Al2( C2H5)6 (abbreviated as Al2Et6 or TEA), as it exists as a dimer. This colorless liquid is pyrophoric. It is an industrially important compound, closely related to trimethylaluminium. Structure and bonding The structure and bonding in Al2R6 and diborane are analogous (R = alkyl). Referring to Al2Me6, the Al-C(terminal) and Al-C(bridging) distances are 1.97 and 2.14 Å, respectively. The Al center is tetrahedral. The carbon atoms of the bridging ethyl groups are each surrounded by five neighbors: carbon, two hydrogen atoms and two aluminium atoms. The ethyl groups interchange readily intramolecularly. At higher temperatures, the dimer cracks into monomeric AlEt3. Synthesis and reactions Triethylaluminium can be formed via several routes. The discovery of an efficient route was a significant technological achievement. The multistep process uses alumini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flamethrower
A flamethrower is a ranged incendiary device designed to project a controllable jet of fire. First deployed by the Byzantine Empire in the 7th century AD, flamethrowers saw use in modern times during World War I, and more widely in World War II as a tactical siege weapon against fortifications. Most military flamethrowers use liquid fuel, typically either gasoline or diesel, but commercial flamethrowers are generally blowtorches using gaseous fuels such as propane; gases are safer in peacetime applications, because their flames have less mass flow rate and dissipate faster, and often are easier to extinguish when necessary. The military use of flamethrowers is restricted through the Protocol on Incendiary Weapons. Apart from the military applications, flamethrowers have peacetime applications where there is a need for controlled burning, such as in sugarcane harvesting and other land-management tasks. Various forms are designed for an operator to carry, while others ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M2 Flamethrower
The M2 flamethrower was an American, man-portable, backpack flamethrower that was used in World War II, the Korean War, and the Vietnam War. The M2 was the successor to the M1 and M1A1 flamethrowers. Although its burn time was around 7 seconds long, and the flames were effective around 20–40 meters, it was still a useful weapon. With the arrival of flamethrower tanks, the need for flamethrower-carrying infantrymen to expose themselves to enemy fire had been greatly reduced. Though some M2s were sold off, the majority were scrapped. Combat use Second World War The M2 flamethrower saw combat use in the Pacific theater, being deployed to combat strongly fortified and entrenched Japanese positions. Following the success with the M1 flamethrower, the M2 was developed and put into combat use in 1943. Towards the end of the conflict, later models of the M2 were equipped with the fuel-thickening agent known as napalm. Variants of the M2 The M2, which was the WWII model, had hexagon ...

Shoulder-launched Missile Weapon
A shoulder-fired missile, shoulder-launched missile, man-portable rocket launcher, or man-portable missile is a rocket-propelled explosive projectile small enough to be carried by a single person and fired while held on one's shoulder. The word "''missile''" in this context is used in its original broad sense of a heavy projectile, and encompasses all guided missiles and unguided rockets. In many instances, although not technically defining all shoulder-fired missiles, the name ''bazooka'' is regularly used as an informal name, although the actual Bazooka is a type of unguided rocket launcher in its own right. Types There are two kinds of shoulder-launched weapons. The first is the recoilless gun, which is essentially an open- breech cannon. When fired, the propellant gases are expelled out of the back of the weapon to alleviate the reactional force exerted from the projectile moving forward. The other type is the rocket-propelled grenade; these typically also use a sma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Marine Corps
The United States Marine Corps (USMC), also referred to as the United States Marines, is the maritime land force service branch of the United States Armed Forces responsible for conducting expeditionary and amphibious operations through combined arms, implementing its own infantry, artillery, aerial, and special operations forces. The U.S. Marine Corps is one of the eight uniformed services of the United States. The Marine Corps has been part of the U.S. Department of the Navy since 30 June 1834 with its sister service, the United States Navy. The USMC operates installations on land and aboard sea-going amphibious warfare ships around the world. Additionally, several of the Marines' tactical aviation squadrons, primarily Marine Fighter Attack squadrons, are also embedded in Navy carrier air wings and operate from the aircraft carriers. The history of the Marine Corps began when two battalions of Continental Marines were formed on 10 November 1775 in Philadelphia ...

Bunker
A bunker is a defensive military fortification designed to protect people and valued materials from falling bombs, artillery, or other attacks. Bunkers are almost always underground, in contrast to blockhouses which are mostly above ground. They were used extensively in World War I, World War II, and the Cold War for weapons facilities, command and control centers, and storage facilities. Bunkers can also be used as protection from tornadoes. Trench bunkers are small concrete structures, partly dug into the ground. Many artillery installations, especially for coastal artillery, have historically been protected by extensive bunker systems. Typical industrial bunkers include mining sites, food storage areas, dumps for materials, data storage, and sometimes living quarters. When a house is purpose-built with a bunker, the normal location is a reinforced below-ground bathroom with fiber-reinforced plastic shells. Bunkers deflect the blast wave from nearby explosions to prevent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rifle Platoon
A platoon is a military unit typically composed of two or more squads, sections, or patrols. Platoon organization varies depending on the country and the branch, but a platoon can be composed of 50 people, although specific platoons may range from 10 to 100 people. A platoon is typically the smallest military unit led by a commissioned officer. The platoon leader is usually a junior officer—a second or first lieutenant or an equivalent rank. The officer is usually assisted by a platoon sergeant. Rifle platoons normally consist of a small platoon headquarters and three or four sections (Commonwealth) or squads (United States). In some armies, platoon is used throughout the branches of the army. In a few armies, such as the French Army, a platoon is specifically a cavalry unit, and the infantry use "section" as the equivalent unit. A unit consisting of several platoons is called a company or a battery. Etymology According to Merriam-Webster, "The term was first use ...

United States Department Of The Navy
The United States Department of the Navy (DoN) is one of the three military departments within the Department of Defense of the United States of America. It was established by an Act of Congress on 30 April 1798, at the urging of Secretary of War James McHenry, to provide a government organizational structure to the United States Navy (USN);Bernard C. Steiner and James McHenry, The life and correspondence of James McHenry' (Cleveland: Burrows Brothers Co., 1907). since 1834, it has exercised jurisdiction over the U.S. Marine Corps (USMC) and, during wartime, the U.S. Coast Guard (USCG), though each remains an independent service branch. It is led by the Secretary of the Navy (SECNAV), a statutory civilian officer. The Department of the Navy was an executive department, whose secretary served on the president's cabinet, until 1949, when amendments to the National Security Act of 1947 established the Department of Defense as a unified department for all military servic ...

List Of United States Marine Corps MOS
The United States Marine Corps Military Occupational Specialty (MOS) is a system of categorizing career fields. All enlisted and officer Marines are assigned a four-digit code denoting their primary occupational field and specialty. Additional MOSs may be assigned through a combination of training and/or experience, which may or may not include completion of a formal school and assignment of a formal school code. Occupational Fields (OccFlds) are identified in the first two digits and represents a grouping of related MOSs. Job codes are identified in the last two digits and represent a specific job within that OccFld. The USMC now publishes an annual Navy/Marine Corps joint publication (NAVMC) directive in the 1200 Standard Subject Identification Code (SSIC) series to capture changes to the MOS system. Previous versions of MCO 1200.17_ series directives are cancelled, including MCO 1200.17E, the last in the series before beginning the annual NAVMC-type directive series. On 3 ...
