82-PM-37
The M-37 or 82-BM-37 (батальонный миномёт, battalion mortar) is a Soviet 82 millimeter calibre mortar designed by B.I. Szayrin and accepted into service in 1937. The design of the M-37 is based on the earlier French Brandt mle 27/31 mortar with Russian modifications. The main difference between the 82-PM-37 and the earlier 82-PM-36 was the adoption of a round base-plate, revised traverse/elevation controls, simplified sights and spring-loaded shock absorbers on the bi-pod to reduce the amount of relaying needed between shots. It was designed to be able to fire western 81 mm captured ammunition whilst not permitting the enemy the same advantage The German designation for captured M-37 mortars was ''8.2 cm GrW 274/2(r)''. The M-37M is an improved version with lighter base plate and a device to prevent double loading. It was produced in China by Norinco as the Type 53, in Egypt by the Helwan Machine Tools Company as the Model 69 and in Bulgaria by Arsenal ...

Infantry Mortar
A mortar is usually a simple, lightweight, man-portable, muzzle-loaded weapon, consisting of a smooth-bore (although some models use a rifled barrel) metal tube fixed to a base plate (to spread out the recoil) with a lightweight bipod mount and a sight. They launch explosive shells (technically called bombs) in high-arcing ballistic trajectories. Mortars are typically used as indirect fire weapons for close fire support with a variety of ammunition. History Mortars have been used for hundreds of years. The earliest mortars were used in Korea in a 1413 naval battle when Korean gunsmiths developed the ''wan'gu'' (gourd-shaped mortar) (완구, 碗口). The earliest version of the ''wan'gu'' dates back to 1407. Choi Hae-san (최해산, 崔海山) (1380–1443), the son of Choe Mu-seon (최무선, 崔茂宣) (1325–1395), is generally credited with inventing the ''wan'gu''. In the Ming dynasty, general Qi Jiguang recorded the use of a mini cannon called the Hu dun pao that was simi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

8 (eight) is the natural number following 7 and preceding 9. In mathematics 8 is: * a composite number, its proper divisors being , , and . It is twice 4 or four times 2. * a power of two, being 2 (two cubed), and is the first number of the form , being an integer greater than 1. * the first number which is neither prime nor semiprime. * the base of the octal number system, which is mostly used with computers. In octal, one digit represents three bits. In modern computers, a byte is a grouping of eight bits, also called an octet. * a Fibonacci number, being plus . The next Fibonacci number is . 8 is the only positive Fibonacci number, aside from 1, that is a perfect cube. * the only nonzero perfect power that is one less than another perfect power, by Mihăilescu's Theorem. * the order of the smallest non-abelian group all of whose subgroups are normal. * the dimension of the octonions and is the highest possible dimension of a normed division algebra. * the first number ...

World War II Infantry Mortars Of The Soviet Union
In its most general sense, the term "world" refers to the totality of entities, to the whole of reality or to everything that is. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique while others talk of a "plurality of worlds". Some treat the world as one simple object while others analyze the world as a complex made up of many parts. In ''scientific cosmology'' the world or universe is commonly defined as " e totality of all space and time; all that is, has been, and will be". '' Theories of modality'', on the other hand, talk of possible worlds as complete and consistent ways how things could have been. ''Phenomenology'', starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon or the "horizon of all horizons". In ''philosophy of mind'', the world is commonly contrasted with the mind as that which is represented by the mind. ''Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cold War Weapons Of The Soviet Union
Cold is the presence of low temperature, especially in the atmosphere. In common usage, cold is often a subjective perception. A lower bound to temperature is absolute zero, defined as 0.00K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to on the Celsius scale, on the Fahrenheit scale, and on the Rankine scale. Since temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in the classical physics, classical sense. The object could be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy even at absol ...

Battle Of Khe Sanh
The Battle of Khe Sanh (21 January – 9 July 1968) was conducted in the Khe Sanh area of northwestern Quảng Trị Province, Republic of Vietnam (South Vietnam), during the Vietnam War. The main US forces defending Khe Sanh Combat Base (KSCB) were two regiments of the United States Marine Corps supported by elements from the United States Army and the United States Air Force (USAF), as well as a small number of Army of the Republic of Vietnam (ARVN) troops. These were pitted against two to three divisional-size elements of the North Vietnamese People's Army of Vietnam (PAVN). The US command in Saigon initially believed that combat operations around KSCB during 1967 were part of a series of minor PAVN offensives in the border regions. That appraisal was later altered when the PAVN was found to be moving major forces into the area. In response, US forces were built up before the PAVN isolated the Marine base. Once the base came under siege, a series of actions were fought over ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armed Forces Of Malta
The Armed Forces of Malta ( mt, Forzi Armati ta' Malta) is the name given to the combined armed services of Malta. The AFM is a brigade sized organisation consisting of a headquarters and three separate battalions, with minimal air and naval forces. Since Malta is the guardian of the European Union's most southerly border, the AFM has an active role in border control. History In April 1800, while the blockade of Valletta was underway, Thomas Graham raised the first official Maltese Troops in the British Army, which became known as the Maltese Light Infantry. This battalion was disbanded in 1802 and succeeded by the Maltese Provincial Battalions, the Malta Coast Artillery and the Maltese Veterans. In 1815, Lieutenant Colonel Count Francis Rivarola was entrusted with the task of raising the Royal Malta Fencible Regiment following the disbandment of the Provincials, Veterans and Coast Artillery. The Royal Malta Fencible Regiment was converted to an artillery regiment in 186 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

People's Republic Of Kampuchea
The People's Republic of Kampuchea (PRK), UNGEGN: , ALA-LC: ; vi, Cộng hòa Nhân dân Campuchia was a partially recognised state in Southeast Asia supported by Vietnam which existed from 1979 to 1989. It was founded in Cambodia by the Kampuchean United Front for National Salvation, a group of Cambodian communists who were dissatisfied with the Khmer Rouge due to its oppressive rule of Cambodia and defected from it after the overthrow of Democratic Kampuchea, Pol Pot's government. Brought about by an invasion from Vietnam, which routed the Khmer Rouge armies, it had Vietnam and the Soviet Union as its main allies. The PRK failed to secure United Nations endorsement due to the diplomatic intervention of China, the United Kingdom, the United States and the ASEAN countries. The Cambodian seat at the United Nations was held by the Coalition Government of Democratic Kampuchea, which was the Khmer Rouge in coalition with two non-communist guerrilla factions. However, the PRK w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
