M270 Multiple Launch Rocket System
The M270 Multiple Launch Rocket System (M270 MLRS) is an American-developed armored, self-propelled, multiple rocket launcher. The U.S. Army variant of the MLRS vehicle is based on the chassis of the Bradley Fighting Vehicle. The first M270s were delivered in 1983. The MLRS were subsequently adopted by several NATO countries and other countries. The MLRS first saw service with the United States in the 1991 Gulf War. The MLRS has been upgraded to fire guided missiles, and has been used by Ukraine in the 2022 Russian invasion of Ukraine. Description Background In the early 1970s, the Soviet Union had a clear advantage over U.S. and NATO forces in terms of rocket artillery. Soviet tactics of bombardment by large numbers of truck-mounted multiple rocket launchers (MRLs), such as the BM-21, would saturate a target area with thousands of rockets, ensuring some would hit specific targets while delivering a psychological impact. By contrast, U.S. artillerists favored cannon artiller ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1973 Yom Kippur War
The Yom Kippur War, also known as the Ramadan War, the October War, the 1973 Arab–Israeli War, or the Fourth Arab–Israeli War, was an armed conflict fought from October 6 to 25, 1973 between Israel and a coalition of Arab states led by Egypt and Syria. The majority of combat between the two sides took place in the Sinai Peninsula and the Golan Heights—both of which were occupied by Israel in 1967—with some fighting in African Egypt and northern Israel. Egypt's initial objective in the war was to seize a foothold on the eastern bank of the Suez Canal and subsequently leverage these gains to negotiate the return of the rest of the Israeli-occupied Sinai Peninsula. The war began on October 6, 1973, when the Arab coalition jointly launched a surprise attack against Israel on the Jewish holy day of Yom Kippur, which had occurred during the 10th of the Islamic holy month of Ramadan in that year. Following the outbreak of hostilities, both the United States and the Sovie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BM-21
The BM-21 "Grad" (russian: БМ-21 "Град", lit= hail) is a self-propelled 122 mm multiple rocket launcher designed in the Soviet Union. The system and the M-21OF rocket were first developed in the early 1960s, and saw their first combat use in March 1969 during the Sino-Soviet border conflict. ''BM'' stands for ''boyevaya mashina'' ( ru , боевая машина – combat vehicle), and the nickname means "hail". The complete system with the BM-21 launch vehicle and the M-21OF rocket is designated as the M-21 field-rocket system. The complete system is more commonly known as a Grad multiple rocket launcher system. In NATO countries the system, either the complete system or the launch vehicle only, was initially known as the M1964. Several other countries have copied the Grad or have developed similar systems. In Russian service its intended replacement is the 9A52-4 Tornado. Many similar 122 mm MLRS systems are made by different countries based on the BM-21 Grad. ...

Member States Of NATO
NATO (North Atlantic Treaty Organization) is an international military alliance that consists of 30 member states from Europe and North America. It was established at the signing of the North Atlantic Treaty on 4 April 1949. Article 5 of the treaty states that if an armed attack occurs against one of the member states, it shall be considered an attack against all members, and other members shall assist the attacked member, with armed forces if necessary. Article 6 of the treaty limits the scope of Article 5 to the islands north of the Tropic of Cancer, the North American and European mainlands, the entirety of Turkey, and French Algeria. As such, an attack on Hawaii, Puerto Rico, French Guiana, Ceuta, or Melilla, among other places, would not trigger an Article 5 response. Of the 30 member countries, 28 are in Europe and two in North America. Between 1994 and 1997, wider forums for regional cooperation between NATO and its neighbours were set up, including the Partnership fo ...

Bradley Fighting Vehicle
The Bradley Fighting Vehicle (BFV) is a tracked armoured fighting vehicle platform of the United States developed by FMC Corporation and manufactured by BAE Systems Land & Armaments, formerly United Defense. It is named after U.S. General Omar Bradley. The Bradley is designed to transport infantry or scouts with armor protection, while providing covering fire to suppress enemy troops and armored vehicles. The several Bradley variants include the M2 Bradley infantry fighting vehicle and the M3 Bradley reconnaissance and infantry fighting vehicle. The M2 holds a crew of three (a commander, a gunner, and a driver) along with six fully equipped soldiers. The M3 mainly conducts scout missions and carries two scout troopers in addition to the regular crew of three, with space for additional BGM-71 TOW missiles. In 2014, the U.S. Army selected BAE Systems Armored Multi-Purpose Vehicle (AMPV) proposal of a turretless variant of the BFV to replace over 2800 M113s in service. Design ...

Multiple Rocket Launcher
A multiple rocket launcher (MRL) or multiple launch rocket system (MLRS) is a type of rocket artillery system that contains multiple launchers which are fixed to a single platform, and shoots its rocket ordnance in a fashion similar to a volley gun. Rockets are self-propelled in flight and have different capabilities than conventional artillery shells, such as longer effective range, lower recoil, typically considerably higher payload than a similarly sized gun artillery platform, or even carrying multiple warheads. Unguided rocket artillery is notoriously inaccurate and slow to reload compared to gun artillery. A multiple rocket launcher helps compensate for this with its ability to launch multiple rockets in rapid succession, which, coupled with the large kill zone of each warhead, can easily deliver saturation fire over a target area. However, modern rockets can use GPS or inertial guidance to combine the advantages of rockets with the higher accuracy of precision-guided mu ...

Self-propelled Artillery
Self-propelled artillery (also called locomotive artillery) is artillery equipped with its own propulsion system to move toward its firing position. Within the terminology are the self-propelled gun, self-propelled howitzer, self-propelled mortar, and rocket artillery. They are high mobility vehicles, usually based on continuous tracks carrying either a large field gun, howitzer, mortar, or some form of rocket/missile launcher. They are usually used for long-range indirect bombardment support on the battlefield. In the past, self-propelled artillery has included direct-fire vehicles, such as assault guns and anti-tank guns ( tank destroyers). These have been armoured vehicles, the former providing close fire-support for infantry and the latter acting as specialized anti-tank vehicles. Modern self-propelled artillery vehicles often mount their main gun in a turret on a tracked chassis so they superficially resemble tanks. However they are generally lightly armoured which ...

Armoured Fighting Vehicle
An armoured fighting vehicle (AFV) is an armed combat vehicle protected by armour, generally combining operational mobility with offensive and defensive capabilities. AFVs can be wheeled or tracked. Examples of AFVs are tanks, armoured cars, assault guns, self-propelled guns, infantry fighting vehicles, and armoured personnel carriers. Armoured fighting vehicles are classified according to their characteristics and intended role on the battlefield. The classifications are not absolute; two countries may classify the same vehicle differently, and the criteria change over time. For example, relatively lightly armed armoured personnel carriers were largely superseded by infantry fighting vehicles with much heavier armament in a similar role. Successful designs are often adapted to a wide variety of applications. For example, the MOWAG Piranha, originally designed as an APC, has been adapted to fill numerous roles such as a mortar carrier, infantry fighting vehicle, and ...

Torsion Bar
A torsion bar suspension, also known as a torsion spring suspension, is any vehicle suspension that uses a torsion bar as its main weight-bearing spring. One end of a long metal bar is attached firmly to the vehicle chassis; the opposite end terminates in a lever, the torsion key, mounted perpendicular to the bar, that is attached to a suspension arm, a spindle, or the axle. Vertical motion of the wheel causes the bar to twist around its axis and is resisted by the bar's torsion resistance. The effective spring rate of the bar is determined by its length, cross section, shape, material, and manufacturing process. Usage Torsion bar suspensions are used on combat vehicles and tanks like the T-72, Leopard 1, Leopard 2, M26 Pershing, M18 Hellcat, M48 Patton, M60 Patton and the M1 Abrams (many tanks from World War II used this suspension), and on modern trucks and SUVs from Ford, Chrysler, GM, Mitsubishi, Mazda, Nissan, Isuzu, LuAZ, and Toyota.

Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
