M9 Armored Combat Earthmover
The M9 Armored Combat Earthmover (ACE) is a highly mobile armored tracked vehicle that provides combat engineer support to front-line forces. Fielded by the United States Army, its tasks include eliminating enemy obstacles, maintenance and repair of roads and supply routes, and construction of fighting positions. History The M9 grew out of the Universal Engineer Tractor- "UET", a follow-on to 1958's All-purpose Ballastable Crawler (tractor) or "ABC". By making a small tractor/scraper, it was possible to create a lightweight vehicle that could use local material as ballast. The weight was kept low enough to allow transportation in smaller cargo aircraft, to be air-droppable, and to allow the vehicle to float and swim. Initial development was between the Engineer Laboratory at Fort Belvoir, with International Harvester and Caterpillar. Successful in testing, and exciting a good deal of interest for civilian spin-off, the concept languished after a demonstration, where key decisi ...

Combat Engineering Vehicle
A military engineering vehicle is a vehicle built for construction work or for the transportation of combat engineering, combat engineers on the battlefield. These vehicles may be modified civilian equipment (such as the Armored bulldozer, armoured bulldozers that many nations field) or purpose-built military vehicles (such as the AVRE). The first appearance of such vehicles coincided with the appearance of the first tanks, these vehicles were modified Mark I tank, Mark V tanks for bridging and mine clearance. Modern ''military engineering vehicles'' are expected to fulfill numerous roles, as such they undertake numerous forms, examples of roles include; bulldozers, crane (machine), cranes, graders, excavators, dump trucks, breaching vehicles, bridging vehicles, military ferries, amphibious crossing vehicles, and combat engineer section carriers. History World War One A Heavy RE tank was developed shortly after World War I by Major Giffard LeQuesne Martel RE. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suspension (vehicle)
Suspension is the system of tires, tire air, springs, shock absorbers and linkages that connects a vehicle to its wheels and allows relative motion between the two. Suspension systems must support both road holding/ handling and ride quality, which are at odds with each other. The tuning of suspensions involves finding the right compromise. It is important for the suspension to keep the road wheel in contact with the road surface as much as possible, because all the road or ground forces acting on the vehicle do so through the contact patches of the tires. The suspension also protects the vehicle itself and any cargo or luggage from damage and wear. The design of front and rear suspension of a car may be different. History An early form of suspension on ox-drawn carts had the platform swing on iron chains attached to the wheeled frame of the carriage. This system remained the basis for most suspension systems until the turn of the 19th century, although the iron cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Periscope
A periscope is an instrument for observation over, around or through an object, obstacle or condition that prevents direct line-of-sight observation from an observer's current position. In its simplest form, it consists of an outer case with mirrors at each end set parallel to each other at a 45° angle. This form of periscope, with the addition of two simple lenses, served for observation purposes in the trenches during World War I. Military personnel also use periscopes in some gun turrets and in armoured vehicles. More complex periscopes using prisms or advanced fiber optics instead of mirrors and providing magnification operate on submarines and in various fields of science. The overall design of the classical submarine periscope is very simple: two telescopes pointed into each other. If the two telescopes have different individual magnification, the difference between them causes an overall magnification or reduction. Early examples Johannes Hevelius described an early ...

Telescope
A telescope is a device used to observe distant objects by their emission, absorption, or reflection of electromagnetic radiation. Originally meaning only an optical instrument using lenses, curved mirrors, or a combination of both to observe distant objects, the word ''telescope'' now refers to a wide range of instruments capable of detecting different regions of the electromagnetic spectrum, and in some cases other types of detectors. The first known practical telescopes were refracting telescopes with glass lenses and were invented in the Netherlands at the beginning of the 17th century. They were used for both terrestrial applications and astronomy. The reflecting telescope, which uses mirrors to collect and focus light, was invented within a few decades of the first refracting telescope. In the 20th century, many new types of telescopes were invented, including radio telescopes in the 1930s and infrared telescopes in the 1960s. Etymology The word ''telescope'' was coin ...

Gulf War
The Gulf War was a 1990–1991 armed campaign waged by a 35-country military coalition in response to the Iraqi invasion of Kuwait. Spearheaded by the United States, the coalition's efforts against Iraq were carried out in two key phases: Operation Desert Shield, which marked the military buildup from August 1990 to January 1991; and Operation Desert Storm, which began with the aerial bombing campaign against Iraq on 17 January 1991 and came to a close with the American-led Liberation of Kuwait on 28 February 1991. On 2 August 1990, Iraq invaded the neighbouring State of Kuwait and had fully occupied the country within two days. Initially, Iraq ran the occupied territory under a puppet government known as the "Republic of Kuwait" before proceeding with an outright annexation in which Kuwaiti sovereign territory was split, with the "Saddamiyat al-Mitla' District" being carved out of the country's northern portion and the "Kuwait Governorate" covering the rest.

Mobility (military)
Mobility in military terms refers to the ability of a weapon system, combat unit or armed force to move toward a military objective. Combat forces with a higher mobility are able to move more quickly, and/or across more hostile terrain, than forces with lower mobility. Mobility is regarded as a vital component of the modern battlefield, as the ability to deliver weapon systems or combat units to their objective quickly can often mean the difference between victory and defeat. Armies around the world have massively increased their mobility over the last 100 years. In World War I, for example, most combat units could move on the battlefield only as fast as a soldier could walk. In the face of overwhelming firepower presented by machine guns and artillery, that resulted in stalemate and an inability to outmaneuver the enemy. By World War II, battlefield mobility had greatly improved with the development of the tank, and with tracked and other mechanized vehicles, to move forces to, f ...

Company (military Unit)
A company is a military unit, typically consisting of 80–250 soldiers and usually commanded by a major or a captain. Most companies are formed of three to seven platoons, although the exact number may vary by country, unit type, and structure. Usually several companies are grouped as a battalion or regiment, the latter of which is sometimes formed by several battalions. Occasionally, ''independent'' or ''separate'' companies are organized for special purposes, such as the 1st Air Naval Gunfire Liaison Company or the 3rd Force Reconnaissance Company. These companies are not organic to a battalion or regiment, but rather report directly to a higher level organization such as a Marine Expeditionary Force headquarters (i.e., a corps-level command). Historical background The modern military company became popularized during the reorganization of the Swedish Army in 1631 under King Gustav II Adolph. For administrative purposes, the infantry was divided into companies consist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battalion
A battalion is a military unit, typically consisting of 300 to 1,200 soldiers commanded by a lieutenant colonel, and subdivided into a number of companies (usually each commanded by a major or a captain). In some countries, battalions are exclusively infantry, while in others battalions are unit-level organizations. The word battalion came into the English language in the 16th century from the French language ( French: ''bataillon'' meaning "battle squadron"; Italian: ''battaglione'' meaning the same thing; derived from the Vulgar Latin word ''battalia'' meaning "battle" and from the Latin word ''bauttere'' meaning "to beat" or "to strike"). The first use of the word in English was in the 1580s. Description A battalion comprises two or more primary mission companies which are often of a common type (e.g., infantry, tank, or maintenance), although there are exceptions such as combined arms battalions in the U.S. Army. In addition to the primary mission companies, a battal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Actuators
An actuator is a component of a machine that is responsible for moving and controlling a mechanism or system, for example by opening a valve. In simple terms, it is a "mover". An actuator requires a control device (controlled by control signal) and a source of energy. The control signal is relatively low energy and may be electric voltage or current, pneumatic, or hydraulic fluid pressure, or even human power. Its main energy source may be an electric current, hydraulic pressure, or pneumatic pressure. The Control device is usually a valve. When it receives a control signal, an actuator responds by converting the source's energy into mechanical motion. In the ''electric'', ''hydraulic'', and ''pneumatic'' sense, it is a form of automation or automatic control. History The history of the pneumatic actuation system and the hydraulic actuation system dates to around the time of World War II (1938). It was first created by Xhiter Anckeleman who used his knowledge of engines and brake ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydropneumatic
Hydropneumatic suspension is a type of motor vehicle suspension system, designed by Paul Magès, invented by Citroën, and fitted to Citroën cars, as well as being used under licence by other car manufacturers, notably Rolls-Royce ( Silver Shadow), Bmw 5-Series e34 Touring, Maserati (Quattroporte II) and Peugeot. It was also used on Berliet trucks and has more recently been used on Mercedes-Benz cars, where it is known as ''Active Body Control.'' The Toyota Soarer UZZ32 "Limited" was fitted with a fully integrated four-wheel steering and a complex, computer-controlled hydraulic ''Toyota Active Control Suspension'' in 1991. Similar systems are also widely used on modern tanks and other large military vehicles. The suspension was referred to as ''oléopneumatique'' in early literature, pointing to oil and air as its main components. The purpose of this system is to provide a sensitive, dynamic and high-capacity suspension that offers superior ride quality on a variety of surface ...

Ballast
Ballast is material that is used to provide stability to a vehicle or structure. Ballast, other than cargo, may be placed in a vehicle, often a ship or the gondola of a balloon or airship, to provide stability. A compartment within a boat, ship, submarine, or other floating structure that holds water is called a ballast tank. Water should move in and out from the ballast tank to balance the ship. In a vessel that travels on the water, the ballast will remain below the water level, to counteract the effects of weight above the water level. The ballast may be redistributed in the vessel or disposed of altogether to change its effects on the movement of the vessel. History The basic concept behind the ballast tank can be seen in many forms of aquatic life, such as the blowfish or members of the argonaut group of octopus. The concept has been invented and reinvented many times by humans to serve a variety of purposes. In the fifteenth and sixteenth century, the ballast "did not cons ...
