M20 Recoilless Rifle
The M20 recoilless rifle is a U.S. 75 mm caliber recoilless rifle T21E12 that was used during the last months of the Second World War and extensively during the Korean War. It could be fired from an M1917A1 .30 caliber machine gun tripod, or from a vehicle mount, typically a Jeep. Its shaped charge warhead, also known as HEAT, was capable of penetrating 100 mm of armor. Although the weapon proved ineffective against the T-34 tank during the Korean War and most other tanks, it was used primarily as a close infantry support weapon to engage all types of targets including infantry and lightly armored vehicles. The M20 proved useful against pillboxes and other types of field fortifications. History During World War II, the U.S. military recognized that, due to advancements in armor technology by enemy forces, a powerful lightweight weapon was needed to defend infantry and light armor units. The Ordnance Department Small Arms Division commenced development of a recoilless ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Recoilless Rifle
A recoilless rifle, recoilless launcher or recoilless gun, sometimes abbreviated "RR" or "RCL" (for ReCoilLess) is a type of lightweight artillery system or man-portable launcher that is designed to eject some form of countermass such as propellant gas from the rear of the weapon at the moment of firing, creating forward thrust that counteracts most of the weapon's recoil. This allows for the elimination of much of the heavy and bulky recoil-counteracting equipment of a conventional cannon as well as a thinner-walled barrel, and thus the launch of a relatively large projectile from a platform that would not be capable of handling the weight or recoil of a conventional gun of the same size. Technically, only devices that use spin-stabilized projectiles fired from a rifled barrel are recoilless rifles, while smoothbore variants (which can be fin-stabilized or unstabilized) are recoilless guns. This distinction is often lost, and both are often called recoilless rifles. Though sim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Lebanese Resistance Regiments
The Lebanese Resistance Regiments ( ar, أفواج المقاومة اللبنانية , ''ʾAfwāj al-Muqāwama al-Lubnāniyya'', ʾAMAL), also designated Lebanese Resistance Battalions, Lebanese Resistance Detachments, Lebanese Resistance Legions and Battalions de la Resistance Libanaise (BRL) or Légions de la Resistance Libanaise (LRL) in French, but simply known by its Arabic acronym ʾAmal which means "Hope", were the military wing of the Movement of the Dispossessed or Movement of the Deprived, a political organization representing the Muslim Shia community of Lebanon. The movement's political wing was officially founded in February 1973 from a previous organization bearing the same name and its military wing was formed in January 1975. The Amal militia was a major player in the Lebanese Civil War from 1975 to 1991. The militia has now been disarmed, though the movement itself, now known as the Amal Movement (Arabic: ''Harakat Amal''), is a notable Shia political par ...

Guerrillas
Guerrilla warfare is a form of irregular warfare in which small groups of combatants, such as paramilitary personnel, armed civilians, or irregulars, use military tactics including ambushes, sabotage, raids, petty warfare, hit-and-run tactics, and mobility, to fight a larger and less-mobile traditional military. Although the term "guerrilla warfare" was coined in the context of the Peninsular War in the 19th century, the tactical methods of guerrilla warfare have long been in use. In the 6th century BC, Sun Tzu proposed the use of guerrilla-style tactics in ''The Art of War''. The 3rd century BC Roman general Quintus Fabius Maximus Verrucosus is also credited with inventing many of the tactics of guerrilla warfare through what is today called the Fabian strategy. Guerrilla warfare has been used by various factions throughout history and is particularly associated with revolutionary movements and popular resistance against invading or occupying armies. Guerrilla tactics focus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The cards proved popular, and the artist Dick Ward proposed the idea of publishing illustrated books about military aircraft. The idea was approved and a small subsidiary company called Osprey was formed in 1968. The company’s first book, ''North American P-51D Mustang in USAAF-USAF Ser ...

The Polisario Front, Frente Polisario, Frelisario or simply Polisario, from the Spanish abbreviation of (Popular Front for the Liberation of Saguia el-Hamra and Río de Oro), (in ar, rtl=yes, الجبهة الشعبية لتحرير الساقية الحمراء ووادي الذهب, al-Jabhah al-Shaʿbiyah Li-Taḥrīr as-Sāqiyah al-Ḥamrāʾ wa Wādī al-Dhahab), is a rebel Sahrawi nationalist liberation movement claiming Western Sahara.

The Polisario Front waged a war to drive out the two armies. It forced Mauritania to relinquish its claim over Western Sahara in 1979 and continu ...

National Park Service
The National Park Service (NPS) is an agency of the United States federal government within the U.S. Department of the Interior that manages all national parks, most national monuments, and other natural, historical, and recreational properties with various title designations. The U.S. Congress created the agency on August 25, 1916, through the National Park Service Organic Act. It is headquartered in Washington, D.C., within the main headquarters of the Department of the Interior.

Avalanche
An avalanche is a rapid flow of snow down a slope, such as a hill or mountain. Avalanches can be set off spontaneously, by such factors as increased precipitation or snowpack weakening, or by external means such as humans, animals, and earthquakes. Primarily composed of flowing snow and air, large avalanches have the capability to capture and move ice, rocks, and trees. Avalanches occur in two general forms, or combinations thereof: slab avalanches made of tightly packed snow, triggered by a collapse of an underlying weak snow layer, and loose snow avalanches made of looser snow. After being set off, avalanches usually accelerate rapidly and grow in mass and volume as they capture more snow. If an avalanche moves fast enough, some of the snow may mix with the air, forming a powder snow avalanche. Though they appear to share similarities, avalanches are distinct from slush flows, mudslides, rock slides, and serac collapses. They are also different from large scale movement ...
