Dispersal (military)
Dispersal is a military practice of dispersing or spreading out potentially vulnerable military assets, such as soldiers, aircraft, ships, tanks, weapons, vehicles, and similar equipment of an army, navy, or air force. Its primary objective is to minimise any potential effects of collateral damage, from incoming munitions such as artillery, bombs and missiles. Dispersal increases the number of artillery rounds needed to neutralise or destroy a military unit in proportion to the dispersal of the said unit. If a division doubles the area it takes up, it will double the number of artillery rounds needed to do the same damage to it. As more targets are spread out or dispersed, more artillery and / or bombs are required to hit all the individual targets. It can also used on a squad level, notably in counter-insurgency, to minimise the effects of grenades, land mines, improvised explosive devices (IEDs), explosive booby traps, and to a lesser extent, automatic gunfire.

A tropical cyclone is a rapidly rotating storm, storm system characterized by a Low-pressure area, low-pressure center, a closed low-level atmospheric circulation, Beaufort scale, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls. Depending on its location and strength, a tropical cyclone is referred to by #Nomenclature and intensity classifications, different names, including hurricane (), typhoon (), tropical storm, cyclonic storm, tropical depression, or simply cyclone. A Atlantic hurricane, hurricane is a strong tropical cyclone that occurs in the Atlantic Ocean or northeastern Pacific Ocean, and a typhoon occurs in the northwestern Pacific Ocean. In the Indian Ocean, South Pacific, or (rarely) South Atlantic, comparable storms are referred to simply as "tropical cyclones", and such storms in the Indian Ocean can also be called "severe cyclonic storms". "Tropical" refers to the geographical origin of these systems, which form al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Covert Cell
A clandestine cell system is a method for organizing a group of people (such as resistance fighters, sleeper agents, mobsters, or terrorists) such that such people can more effectively resist penetration by an opposing organization (such as law enforcement or military units). In a cell structure, each of the small groups of people in the cell know the identities of the people only in their own cell. Thus any cell member who is apprehended and interrogated (or who is a mole) will not likely know the identities of the higher-ranking individuals in the organization. The structure of a clandestine cell system can range from a strict hierarchy to an extremely distributed organization, depending on the group's ideology, its operational area, the communications technologies available, and the nature of the mission. Criminal organizations, undercover operations, and unconventional warfare units led by special forces may also use this sort of organizational structure. Covert op ...

Military Intelligence
Military intelligence is a military discipline that uses information collection and analysis approaches to provide guidance and direction to assist commanders in their decisions. This aim is achieved by providing an assessment of data from a range of sources, directed towards the commanders' mission requirements or responding to questions as part of operational or campaign planning. To provide an analysis, the commander's information requirements are first identified, which are then incorporated into intelligence collection, analysis, and dissemination. Areas of study may include the operational environment, hostile, friendly and neutral forces, the civilian population in an area of combat operations, and other broader areas of interest. Intelligence activities are conducted at all levels, from tactical to strategic, in peacetime, the period of transition to war, and during a war itself. Most governments maintain a military intelligence capability to provide analytical and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Militia
A militia () is generally an army or some other fighting organization of non-professional soldiers, citizens of a country, or subjects of a state, who may perform military service during a time of need, as opposed to a professional force of regular, full-time military personnel; or, historically, to members of a warrior-nobility class (e.g. knights or samurai). Generally unable to hold ground against regular forces, militias commonly support regular troops by skirmishing, holding fortifications, or conducting irregular warfare, instead of undertaking offensive campaigns by themselves. Local civilian laws often limit militias to serve only in their home region, and to serve only for a limited time; this further reduces their use in long military campaigns. Beginning in the late 20th century, some militias (in particular officially recognized and sanctioned militias of a government) act as professional forces, while still being "part-time" or "on-call" organizations.

Guerrilla Warfare
Guerrilla warfare is a form of irregular warfare in which small groups of combatants, such as paramilitary personnel, armed civilians, or Irregular military, irregulars, use military tactics including ambushes, sabotage, Raid (military), raids, petty warfare, hit-and-run tactics, and Mobility (military), 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 agains ...

Booby Trap
A booby trap is a device or setup that is intended to kill, harm or surprise a human or another animal. It is triggered by the presence or actions of the victim and sometimes has some form of bait designed to lure the victim towards it. The trap may be set to act upon trespassers that enter restricted areas, and it can be triggered when the victim performs an action (e.g., opening a door, picking something up, or switching something on). It can also be triggered by vehicles driving along a road, as in the case of improvised explosive devices (IEDs). Booby traps should not be confused with mantraps which are designed to catch a person. Lethal booby traps are often used in warfare, particularly guerrilla warfare, and traps designed to cause injury or pain are also sometimes used by criminals wanting to protect drugs or other illicit property, and by some owners of legal property who wish to protect it from theft. Booby traps which merely cause discomfort or embarrassment are a popul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Improvised Explosive Device
An improvised explosive device (IED) is a bomb constructed and deployed in ways other than in 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. IEDs are generally done in these terrorism operations or in asymmetric unconventional warfare by insurgent guerrillas or commando forces in a theatre of operations. In the Iraq War (2003–2011), insurgents used IEDs extensively against U.S.-led forces and, by the end of 2007, IEDs were responsible for approximately 63% of coalition deaths in Iraq. They were also used in Afghanistan by insurgent groups, and caused over 66% of coalition casualties in the 2001–2021 Afghanistan War. IEDs were also used frequently by the Liberation Tigers of Tamil Eelam (LTTE) in Sri Lanka during the Sri Lankan Civil War. Background An IED is a bomb fabricated in an improvised manner ...

Land Mine
A land mine is an explosive device concealed under or on the ground and designed to destroy or disable enemy targets, ranging from combatants to vehicles and tanks, as they pass over or near it. Such a device is typically detonated automatically by way of pressure when a target steps on it or drives over it, although other detonation mechanisms are also sometimes used. A land mine may cause damage by direct blast effect, by fragments that are thrown by the blast, or by both. Landmines are typically laid throughout an area, creating a ''minefield'' which is dangerous to cross. The use of land mines is controversial because of their potential as indiscriminate weapons. They can remain dangerous many years after a conflict has ended, harming civilians and the economy. Seventy-eight countries are contaminated with land mines and 15,000–20,000 people are killed every year while many more are injured. Approximately 80% of land mine casualties are civilians, with children as the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
