Ground Mobility Vehicle – (US)SOCOM Program
The Ground Mobility Vehicle (GMV) is a U.S. Special Operations Command, (US)SOCOM program, initially modifying Humvees into several variants for use by the United States special operations forces (SOF). Its design is mostly based on lessons learned during Operation Desert Storm in Iraq, after an initial program, post 1985, for specialized HMMWVs for desert strike operations: the Desert Mobility Vehicle (DMV), or "Dumvee". GMV crews like to call them "gun trucks". The GMV program is superseded by the GMV 1.1, based on the General Dynamics Flyer 72. It is understood that under a seven-year indefinite delivery / indefinite-quantity (ID/IQ) contract (August 2013–August 2020), SOCOM wishes to procure 1,297 GMV 1.1s — to replace its 1,072 first generation, Humvee-based GMV units. History The GMV was developed based on U.S. special operation forces Humvees deployed to the Middle East. The program was initially meant to provide equipment related to mountainous deployment. ...

Special Operations
Special operations or special ops 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 counterterrorism, and are typically conducted by small groups of highly trained personnel, emphasizing sufficiency, stealth, speed, and tactical coordination, commonly known as ''special forces'' (SF) or ''special operations forces'' (SOF). 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 Japa ...

United States Special Operations Command
The United States Special Operations Command (USSOCOM or SOCOM) is the unified combatant command charged with overseeing the various special operations component commands of the Army, Marine Corps, Navy, and Air Force of the United States Armed Forces. The command is part of the Department of Defense and is the only unified combatant command created by an Act of Congress. USSOCOM is headquartered at MacDill Air Force Base in Tampa, Florida. The idea of an American unified special operations command had its origins in the aftermath of Operation Eagle Claw, the disastrous attempted rescue of hostages at the American embassy in Iran in 1980. The ensuing investigation, chaired by Admiral James L. Holloway III, the retired Chief of Naval Operations, cited lack of command and control and inter-service coordination as significant factors in the failure of the mission. Since its activation on 16 April 1987, U.S. Special Operations Command has participated in many operations, fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbocharger
In an internal combustion engine, a turbocharger (also known as a turbo or a turbosupercharger) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake air, forcing more air into the engine in order to produce more power for a given displacement. Turbochargers are distinguished from superchargers in that a turbocharger is powered by the kinetic energy of the exhaust gases, whereas a is mechanically powered (usually by a belt from the engine's crankshaft). However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger.

V8 Engine
A V8 engine is an eight- cylinder piston engine in which two banks of four cylinders share a common crankshaft and are arranged in a V configuration. Origins The first known V8 was the Antoinette, designed by Léon Levavasseur, and built in 1904 by the French Antoinette company for use in speedboat racing, cars, and later, airplanes. Also in 1904, V8 engines began small-scale production by Renault and Buchet for use in race cars. Design V-angle Most engines use a V-angle (the angle between the two banks of cylinders) of 90 degrees. This angle results in good engine balance, which results in low vibrations. However, the downside is the greater width of the engine compared to those that use a smaller V-angle. V8 engines with a 60-degree V-angle were used in the 1996–1999 Ford Taurus SHO, the 2005–2011 Volvo XC90, and the 2006–2009 Volvo S80. The Ford engine used a 60-degree V-angle because it was based on a V6 engine with a 60-degree V-angle. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Tire Inflation System
A central tire inflation system (CTIS) is a system to provide control over the air pressure in each of a vehicle's tires as a way to improve performance on different surfaces. Uses Lowering the air pressure in a tire creates a larger contact patch between the tire and the ground, and makes driving on softer ground much easier. It also does less damage to the tire surface. This is important on work sites and in agricultural fields; by giving the driver direct control over the air pressure in each tire, maneuverability is greatly improved. Softer tires also cushion against rough terrain and road damage, such as washboarding, more effectively. Reducing tire pressure also reduces the extent to which the tires grind against loose surfaces, significantly reducing dust and silt. Another function of CTIS is to maintain tire pressure if there is a slow leak or puncture. In this case, the system controls inflation automatically based on the selected pressure the driver has set. CTIS als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain Warfare
Mountain warfare or alpine warfare is warfare in mountains or similarly rough terrain. The term encompasses military operations affected by the terrain, hazards, and factors of combat and movement through rough terrain, as well as the strategies and tactics used by military forces in these situations and environments. Mountain ranges are of strategic importance since they often act as a natural border and may also be the origin of a water source such as the Golan Heights. Attacking a prepared enemy position in mountain terrain generally requires a greater ratio of attacking soldiers to defending soldiers than a war conducted on level ground. Mountains present natural hazards such as lightning, strong gusts of wind, rockfalls, avalanches, snowpacks, ice, extreme cold, and glaciers with their crevasses; in these ways, it can be similar to cold-weather warfare. The generally uneven terrain and the slow pace of troop and material movements are additional threats to combatants. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Middle East
The Middle East (term originally coined in English language) is a geopolitical region encompassing the Arabian Peninsula, the Levant, Turkey, Egypt, Iran, and Iraq. The term came into widespread usage by the United Kingdom and western European nations in the early 20th century as a replacement of the term Near East (both were in contrast to the Far East). The term "Middle East" has led to some confusion over its changing definitions. Since the late 20th century, it has been criticized as being too Eurocentrism, Eurocentric. The region includes the vast majority of the territories included in the closely associated definition of West Asia, but without the South Caucasus. It also includes all of Egypt (not just the Sinai Peninsula, Sinai) and all of Turkey (including East Thrace). Most Middle Eastern countries (13 out of 18) are part of the Arab world. The list of Middle Eastern countries by population, most populous countries in the region are Egypt, Turkey, and Iran, whil ...

Indefinite Delivery/indefinite Quantity
In U.S. Federal government contracting, IDIQ is an abbreviation of the term indefinite delivery/indefinite quantity. This is a type of contract that provides for an indefinite quantity of supplies or services during a fixed period of time. The legal origin of IDIQ contracts is the Federal Acquisition Regulation (FAR) section 16.504(a) (). IDIQs are also sometimes called "Task Orders" or "Delivery Order Contracts." IDIQ contracts are a subtype of Indefinite Delivery Contract (IDC), which is a "vehicle that has been awarded to one or more vendors to facilitate the delivery of supply and service orders." Usage IDIQ contracts are most often used for on-call service contracts, Architect-Engineering (A-E) services, and job order contracting. Awards are usually for a specified number of base years with renewal options for additional years. These contracts typically do not exceed a total of five years in duration. The government places delivery orders (for supplies) or task orders (for s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Desert Warfare
Desert warfare is warfare in deserts or similar arid or semi-arid environments. The term encompasses military operations affected by the terrain, climate, and resource availability of these areas, as well as the strategies and tactics used by military forces in these situations and environments. Desert warfare is distinct from other types of warfare in other environments and terrains, in that the desert is generally considered very inhospitable. The hot temperatures in the day and the cold temperatures in the night, the scarcity of food, water, and plant life, and the lack of cover and concealment, affect how military forces operate in desert environments. The heat and lack of water can sometimes be more dangerous than the enemy. Properties and tactics The barrenness of the desert makes the capture of key cities essential to ensure the ability to maintain control over important resources, primarily clean water, and being able to keep a military well supplied. As such, that mak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Desert
A desert is a landscape where little precipitation occurs and, consequently, living conditions create unique biomes and ecosystems. The lack of vegetation exposes the unprotected surface of the ground to denudation. About one-third of the land surface of the Earth is arid or Semi-arid climate, semi-arid. This includes much of the Polar regions of Earth, polar regions, where little precipitation occurs, and which are sometimes called polar deserts or "cold deserts". Deserts can be classified by the amount of precipitation that falls, by the temperature that prevails, by the causes of desertification or by their geographical location. Deserts are formed by weathering processes as large variations in temperature between day and night strain the Rock (geology), rocks, which consequently break in pieces. Although rain seldom occurs in deserts, there are occasional downpours that can result in flash floods. Rain falling on hot rocks can cause them to shatter, and the resulting frag ...
