M50 Joint Service General Purpose Mask
The M50 series protective mask consisting of the M50 and M51 variants, officially known as the Joint Service General Purpose (JSGPM) is a lightweight, protective mask system consisting of the mask, a mask carrier, and additional accessories. It was adopted by the U.S. military in 2006 and is manufactured by Avon Rubber. The mask was designed/made to incorporate the state-of-the-art technologies to protect United States Armed Forces and the allied forces from current and anticipated threats from all types of weapons of mass destruction. It is an above-the-neck, chemical-biological (CB) respirator that protects against battlefield concentrations of CB agents, toxins, toxic industrial materials and radioactive particulate matter. The M50/51 masks replace the M40 field protective mask and M42, MCU-2/P series masks and the M45 of the Land Warrior Program. There are two mask variants: M50 (ground and shipboard use) and M51 (ground vehicle use). History The M50 series mask entered ser ...

Protective Mask
A mask is an object normally worn on the face, typically for protection, disguise, performance, or entertainment and often they have been employed for rituals and rights. Masks have been used since antiquity for both ceremonial and practical purposes, as well as in the performing arts and for entertainment. They are usually worn on the face, although they may also be positioned for effect elsewhere on the wearer's body. More generally in art history, especially sculpture, "mask" is the term for a face without a body that is not modelled in the round (which would make it a "head"), but for example appears in low relief. Etymology The word "mask" appeared in English in the 1530s, from Middle French ''masque'' "covering to hide or guard the face", derived in turn from Italian ''maschera'', from Medieval Latin ''masca'' "mask, specter, nightmare". This word is of uncertain origin, perhaps from Arabic ''maskharah'' مَسْخَرَۃٌ "buffoon", from the verb ''sakhira'' "t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Weapons Of Mass Destruction
A weapon of mass destruction (WMD) is a chemical, biological, radiological, nuclear, or any other weapon that can kill and bring significant harm to numerous individuals or cause great damage to artificial structures (e.g., buildings), natural structures (e.g., mountains), or the biosphere. The scope and usage of the term has evolved and been disputed, often signifying more politically than technically. Originally coined in reference to aerial bombing with chemical explosives during World War II, it has later come to refer to large-scale weaponry of warfare-related technologies, such as chemical, biological, radiological, or nuclear warfare. Early uses of this term The first use of the term "weapon of mass destruction" on record is by Cosmo Gordon Lang, Archbishop of Canterbury, in 1937 in reference to the aerial bombing of Guernica, Spain: At the time, nuclear weapons had not been developed. Japan conducted research on biological weapons (see Unit 731), and chemical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M40 Field Protective Mask
The M40 field protective mask was one of various protective masks used by the United States Armed Forces and its allies to protect from field concentrations of chemical and biological agents, along with radiological fallout particles. It is not effective in an Oxygen deficiency, oxygen deficient environment or against ammonia. History The M40 was the result of a program in the 1980s to develop a successor to the M17 gas mask, M17-series protective masks which had been in service with the US armed forces since 1959. The M40 was to be a return to conventional protective mask design with an external side-mounted filter canister, rather than the internal cheek filters of the M17, which were awkward to change, especially in a contaminated environment. The final prototype, the XM40, was approved for service and then designated the M40. The M40 was phased into service with the United States Army, U.S. Army and United States Marine Corps, Marine Corps in the mid-1990s, with another ...

MCU-2/P
The MCU-2/P is a protective mask used by the United States Air Force and United States Navy, originally designed for the US Army as the XM-30 mask. In December 1982, the U.S. Air Force took over the XM-30 mask development. In 1983, the U.S. Navy requested the first masks off the production lines since the Army mask was no longer in production and the Navy had none. The Air Force agreed, except to get 5,000 masks to support a 1985 Technology Demonstration. Production began in 1985 and some active duty Sailors and Airmen had a new protective mask before Operation Desert Storm in 1991. It replaced the earlier M17 gas mask and is itself scheduled to be replaced by the M50 joint service general purpose mask. The MCU-2/P features a single large lens and a side-mounted filter. A clear or tinted visor and protective hood are used in conjunction with the mask. Like the Army and USMC M40 mask, the MCU-2/P's silicon rubber facepiece was found to be susceptible to corrosion from blister ...

Special Operations
Special operations (S.O.) are military activities conducted, according to NATO, by "specially designated, organized, selected, trained, and equipped forces using unconventional techniques and modes of employment". Special operations may include reconnaissance, unconventional warfare, and counter-terrorism actions, and are typically conducted by small groups of highly-trained personnel, emphasizing sufficiency, stealth, speed, and tactical coordination, commonly known as " special forces". History Australia In World War II following advice from the British, Australia began raising special forces. The first units to be formed were independent companies, which began training at Wilson's Promontory in Victoria in early 1941 under the tutelage of British instructors. With an establishment of 17 officers and 256 men, the independent companies were trained as "stay behind" forces, a role that they were later employed in against the Japanese in the South West Pacific Area during 1942†...
