Warhead
A warhead is the forward section of a device that contains the explosive agent or toxic (biological, chemical, or nuclear) material that is delivered by a missile, rocket, torpedo, or bomb. Classification Types of warheads include: * Explosive: An explosive charge is used to disintegrate the target, and damage surrounding areas with a blast wave. ** Conventional: Chemicals such as gunpowder and high explosives store significant energy within their molecular bonds. This energy can be released quickly by a trigger, such as an electric spark. Thermobaric weapons enhance the blast effect by utilizing the surrounding atmosphere in their explosive reactions. ***Blast: A strong shock wave is provided by the detonation of the explosive. *** Fragmentation: Metal fragments are projected at high velocity to cause damage or injury. *** Continuous rod: Metal bars welded on their ends form a compact cylinder of interconnected rods, which is violently expanded into a contiguous zig-zag-shape ...

South Korean Army
The Republic of Korea Army (ROKA; ko, 대한민국 육군; Hanja: 大韓民國 陸軍; RR: ''Daehanminguk Yuk-gun''), also known as the ROK Army or South Korean Army, is the army of South Korea, responsible for ground-based warfare. It is the largest of the military branches of the Republic of Korea Armed Forces with 420,000 members . This size is maintained through conscription; South Korean men must complete military service (18 months for army, auxiliary police and marine, 20 months for navy and conscripted firefighter, 21 months for air force and social service, 36 months for alternative service) between the age of 18 and 35. History The modern South Korean army traces its lineage back to the Gwangmu Reform, when the Byeolgigun was established by Emperor Gojong in 1881. The 1st of every October is celebrated in South Korea as Armed Forces Day. It commemorates the day during the Korean War when units of the ROK Army first crossed the 38th Parallel, thus leading the U ...

M270 MLRS
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] |
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 ...

Rocket Artillery
Rocket artillery is artillery that uses rocket explosives as the projectile. The use of rocket artillery dates back to medieval China where devices such as fire arrows were used (albeit mostly as a psychological weapon). Fire arrows were also used in multiple launch systems and transported via carts. First true rocket artillery was developed in India by the Kingdom of Mysore. In the late nineteenth century, due to improvements in the power and range of conventional artillery, the use of early military rockets declined; they were finally used on a small scale by both sides during the American Civil War. Modern rocket artillery was first employed during World War II, in the form of the German Nebelwerfer family of rocket ordnance designs, Soviet Katyusha-series and numerous other systems employed on a smaller scale by the Western allies and Japan. In modern use, the rockets are often guided by an internal guiding system or GPS in order to maintain accuracy. History Early history ...

Hanja
Hanja (Hangul: ; Hanja: , ), alternatively known as Hancha, are Chinese characters () used in the writing of Korean. Hanja was used as early as the Gojoseon period, the first ever Korean kingdom. (, ) refers to Sino-Korean vocabulary, which can be written with Hanja, and (, ) refers to Classical Chinese writing, although "Hanja" is also sometimes used to encompass both concepts. Because Hanja never underwent any major reforms, they are mostly resemble to ''kyūjitai'' and traditional Chinese characters, although the stroke orders for some characters are slightly different. For example, the characters and as well as and . Only a small number of Hanja characters were modified or are unique to Korean, with the rest being identical to the traditional Chinese characters. By contrast, many of the Chinese characters currently in use in mainland China, Malaysia and Singapore have been simplified, and contain fewer strokes than the corresponding Hanja characters.
