Bombs
A bomb is an explosive weapon that uses the Exothermic process, exothermic reaction of an explosive material to provide an extremely sudden and violent release of energy. Detonations inflict damage principally through ground- and atmosphere-transmitted stress (mechanics), mechanical stress, the impact and penetration of pressure-driven projectiles, pressure damage, and explosion-generated effects. Bombs have been utilized since the 11th century starting in East Asia. The term ''bomb'' is not usually applied to explosive devices used for civilian purposes such as construction or mining, although the people using the devices may sometimes refer to them as a "bomb". The military use of the term "bomb", or more specifically aerial bomb action, typically refers to airdropped, unpowered explosive weapons most commonly used by air forces and naval aviation. Other military explosive weapons not classified as "bombs" include shell (projectile), shells, depth charges (used in water), or l ...

Improvised Explosive Device
An improvised explosive device (IED) is a bomb constructed and deployed in ways other than in conventional warfare, conventional military action. It may be constructed of conventional military explosives, such as an artillery shell, attached to a detonating mechanism. IEDs are commonly used as roadside bombs, or homemade bombs. The term "IED" was coined by the British Army during the Northern Ireland conflict to refer to booby traps made by the Provisional Irish Republican Army, IRA, and entered common use in the U.S. during the Iraq War. IEDs are generally utilized in terrorist operations or in asymmetric warfare, asymmetric unconventional warfare or urban warfare by insurgent guerrilla warfare, guerrillas or commando forces in a theater (warfare), theatre of operations. In the Iraq War (2003–2011), Iraqi insurgency (2003–2011), insurgents used IEDs extensively against U.S.-led forces, and by the end of 2007, IEDs were responsible for approximately 63% of Multi-National ...

Aerial Bomb
An aerial bomb is a type of Explosive weapon, explosive or Incendiary device, incendiary weapon intended to travel through the Atmosphere of Earth, air on a predictable trajectory. Engineers usually develop such bombs to be dropped from an aircraft. The use of aerial bombs is termed aerial bombing. Bomb types Aerial bombs include a vast range and complexity of designs. These include unguided Unguided bomb, gravity bombs, guided bombs, bombs hand-tossed from a vehicle, bombs needing a large specially-built delivery-vehicle, bombs integrated with the vehicle itself (such as a glide bomb), instant-detonation bombs, or delay-action bombs. As with other types of explosive weapons, aerial bombs aim to kill and injure people or to destroy materiel through the projection of one or more of blast, fragmentation, radiation or fire outwards from the point of detonation. Early bombs The first bombs delivered to their targets by air were single bombs carried on unmanned Incendiary ballo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thunder Crash Bomb
The thunder crash bomb (), also known as the heaven-shaking-thunder bomb, was one of the first bombs or hand grenades in the history of gunpowder warfare. It was developed in the 12th-13th century Song and Jin dynasties. Its shell was made of cast iron and filled with gunpowder. The length of the fuse could be adjusted according to the intended throwing distance. History Thunderclap bomb (''pilipao'') The ''zhentianlei'' (thunder-crash/heaven-shaking-thunder) bomb was not the first bomb. Gunpowder bombs had been mentioned since the 11th century. In 1000 AD, a soldier by the name of Tang Fu (唐福) demonstrated a design of gunpowder pots (a proto-bomb which spews fire) and gunpowder caltrops, for which he was richly rewarded. In the military text '' Wujing Zongyao'' of 1044, bombs such as the "ten-thousand fire flying sand magic bomb", "burning heaven fierce fire unstoppable bomb", and "thunderclap bomb" (''pilipao'') were mentioned. However these were soft-shell bombs and did ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Unconventional Warfare
Unconventional warfare (UW) is broadly defined as "military and quasi-military operations other than conventional warfare" and may use covert forces or actions such as subversion, diversion, sabotage, espionage, biowarfare, sanctions, propaganda or guerrilla warfare. This is typically done to avoid escalation into conventional warfare as well as international conventions. Description Aside from the earlier definition of warfare that is not conventional, unconventional warfare has also been described as: There is another type of warfare— new in its intensity, ancient in its origin—war by guerrillas, subversives, insurgents, assassins; war by ambush instead of by combat, by infiltration instead of aggression, seeking victory by eroding and exhausting the enemy instead of engaging him. It preys on unrest. Methods and organization Unconventional warfare targets the civilian population psychologically to win hearts and minds, and only targets military and political bo ...

Wind And Dust Bomb
Wind is the natural movement of atmosphere of Earth, air or other gases relative to a planetary surface, planet's surface. Winds occur on a range of scales, from thunderstorm flows lasting tens of minutes, to local breezes generated by heating of land surfaces and lasting a few hours, to global winds resulting from the difference in absorption (electromagnetic radiation), absorption of solar energy between the climate zones on Earth. The study of wind is called anemology. The two main causes of large-scale atmospheric circulation are the differential heating between the equator and the poles, and the rotation of the planet (Coriolis effect). Within the tropics and subtropics, thermal low circulations over terrain and high plateaus can drive monsoon circulations. In coastal areas the sea breeze/land breeze cycle can define local winds; in areas that have variable terrain, mountain and valley breezes can prevail. Winds are commonly classified by their scale (spatial), spatial ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Onomatopoeia
Onomatopoeia (or rarely echoism) is a type of word, or the process of creating a word, that phonetics, phonetically imitates, resembles, or suggests the sound that it describes. Common onomatopoeias in English include animal noises such as Oink (sound), ''oink'', ''meow'', ''roar'', and ''Bird vocalization, chirp'', among other sounds such as ''Beep (sound), beep'' or ''hiccup''. Onomatopoeia can differ by language: it conforms to some extent to the broader natural language, linguistic system. Hence, the sound of a clock may be expressed variously across languages: as ' in English language, English, in Spanish language, Spanish and Italian language, Italian (see photo), in Standard Chinese, Mandarin, in Japanese language, Japanese, or in Hindi, Urdu, and Bengali language, Bengali. Etymology and terminology The word ''onomatopoeia'', with rarer spelling variants like ''onomatopeia'' and ''onomatopœia'', is an English word from the Ancient Greek language, Ancient Greek com ...

Romanized
In linguistics, romanization is the conversion of text from a different writing system to the Roman (Latin) script, or a system for doing so. Methods of romanization include transliteration, for representing written text, and transcription, for representing the spoken word, and combinations of both. Transcription methods can be subdivided into '' phonemic transcription'', which records the phonemes or units of semantic meaning in speech, and more strict ''phonetic transcription'', which records speech sounds with precision. Methods There are many consistent or standardized romanization systems. They can be classified by their characteristics. A particular system's characteristics may make it better-suited for various, sometimes contradictory applications, including document retrieval, linguistic analysis, easy readability, faithful representation of pronunciation. * Source, or donor language – A system may be tailored to romanize text from a particular language, or a seri ...
