Urban Terrain
Urban terrain is a military term for the representation of the urban environment within the context of urban warfare. Urban terrain includes buildings, roads, highways, ports, rails, airports, subways, and sewage lines. Mouse-holing is one military technique used to overcome some of the physical barriers within the urban environment.

Rapid Transit
Rapid transit or mass rapid transit (MRT), also known as heavy rail or metro, is a type of high-capacity public transport generally found in urban areas. A rapid transit system that primarily or traditionally runs below the surface may be called a subway, tube, or underground. Unlike buses or trams, rapid transit systems are railways (usually electric railway, electric) that operate on an exclusive right-of-way (transportation), right-of-way, which cannot be accessed by pedestrians or other vehicles, and which is often grade-separated in tunnels or on elevated railways. Modern services on rapid transit systems are provided on designated lines between rapid transit station, stations typically using electric multiple units on rail tracks, although some systems use guided rubber tires, magnetic levitation (''maglev''), or monorail. The stations typically have high platforms, without steps inside the trains, requiring custom-made trains in order to minimize gaps between train a ...

Military Terminology
Military terminology refers to the terms and language of military organizations and personnel as belonging to a discrete category. As distinguishable by their usage in military doctrine, they serve to depoliticise, dehumanise, or otherwise abstract discussion about its operations from an actual description thereof. Common understanding The operational pressure for uniform understanding has developed since the early 20th century with the importance of joint operations between different services (army, navy, air force) of the same country. International alliances and operations, including peacekeeping, have added additional complexity. For example, the NATO alliance now maintains a large dictionary of common terms for use by member countries. Development work is also taking place between NATO and Russia on common terminology for extended air defence, in English, French and Russian. Criticism Some claim military terms serve to depoliticise, dehumanize, or otherwise abstract d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subterranean Warfare
Subterranean warfare is warfare carried out under the ground surface. Overview Underground military facilities play a key role in many nations, there are more than 10,000 underground military facilities worldwide, as such underground warfare is a nearly inevitable component of modern conflicts. Actors often go underground to counteract overmatch such as that faced when taking on a superpower. History Subterranean warfare was occasionally carried out during World War II. Examples are the defense of the Adzhimushkay quarry, or the use of Odessa Catacombs during guerilla warfare by Soviet partisans. In 21st century the issue of readiness to subterranean warfare was raised before the U.S. military in view of the tunnel tactic of Hamas. A December 11, 2013 RFI (request for information) titled "Technologies to enhance warfighter capabilities in subterranean environments" states in part: In an effort to defeat United States (US) intelligence and weapons technologies and to gain tacti ...

Manhole Cover
A manhole cover or maintenance hole cover is a removable plate forming the lid over the opening of a manhole, an opening large enough for a person to pass through that is used as an access point for an underground vault or pipe. It is designed to prevent anyone or anything from falling in, and to keep out unauthorized persons and material. Manhole covers date back at least to the era of ancient Rome, which had sewer grates made from stone. Description Manhole covers are often made out of cast iron, concrete or a combination of the two. This makes them inexpensive, strong, and heavy, usually weighing more than . The weight helps to keep them in place when traffic passes over them, and makes it difficult for unauthorized people without suitable tools to remove them. Manhole covers may also be made from glass-reinforced plastic or other composite material (especially in Europe, or where cover theft is of concern). Because of law restricting acceptable manual handling weights, Eu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urban Warfare
Urban warfare is combat conducted in urban areas such as towns and cities. Urban combat differs from combat in the open at both the operational and the tactical levels. Complicating factors in urban warfare include the presence of civilians and the complexity of the urban terrain. Urban combat operations may be conducted to capitalize on strategic or tactical advantages associated with the possession or the control of a particular urban area or to deny these advantages to the enemy. Fighting in urban areas negates the advantages that one side may have over the other in armor, heavy artillery, or air support. Ambushes laid down by small groups of soldiers with handheld anti-tank weapons can destroy entire columns of modern armor (as in the First Battle of Grozny), while artillery and air support can be severely reduced if the "superior" party wants to limit civilian casualties as much as possible, but the defending party does not (or even uses civilians as human shields). Some civ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mouse-holing
Mouse-holing is a tactic used in urban warfare in which soldiers create access to adjoining rooms or buildings by blasting or tunneling through a wall. The tactic is used to avoid open streets since advancing infantry, caught in enfilade, are easily targeted by machine-gun and sniper fire. Another purpose is to reach enemy troops hidden within a structure. Use The tactic was used by British soldiers in Dublin during the 1916 Easter Rising. Mouse-holing began to appear in military tactical manuals during World War II. The tactic allows combatants to move around an urban battlefield under cover without needing to expose themselves to enemy fire or observation. A typical passage is large enough for a single file of soldiers. Large unrestricted holes can compromise the structural integrity of the building and offer little cover from opposing forces. During the Battle of Ortona in 1943, the Canadian Army, which gave the tactic its name, used it to great effect, breaching the walls of ...

Sewage
Sewage (or domestic sewage, domestic wastewater, municipal wastewater) is a type of wastewater that is produced by a community of people. It is typically transported through a sewer system. Sewage consists of wastewater discharged from residences and from commercial, institutional and public facilities that exist in the locality. Sub-types of sewage are greywater (from sinks, bathtubs, showers, dishwashers, and clothes washers) and blackwater (the water used to flush toilets, combined with the human waste that it flushes away). Sewage also contains soaps and detergents. Food waste may be present from dishwashing, and food quantities may be increased where garbage disposal units are used. In regions where toilet paper is used rather than bidets, that paper is also added to the sewage. Sewage contains macro-pollutants and micro-pollutants, and may also incorporate some municipal solid waste and pollutants from industrial wastewater. Sewage usually travels from a building's plum ...

Airport
An airport is an aerodrome with extended facilities, mostly for commercial air transport. Airports usually consists of a landing area, which comprises an aerially accessible open space including at least one operationally active surface such as a runway for a plane to take off and to land or a helipad, and often includes adjacent utility buildings such as control towers, hangars and terminals, to maintain and monitor aircraft. Larger airports may have airport aprons, taxiway bridges, air traffic control centres, passenger facilities such as restaurants and lounges, and emergency services. In some countries, the US in particular, airports also typically have one or more fixed-base operators, serving general aviation. Operating airports is extremely complicated, with a complex system of aircraft support services, passenger services, and aircraft control services contained within the operation. Thus airports can be major employers, as well as important hubs for tourism ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urban Area
An urban area, built-up area or urban agglomeration is a human settlement with a high population density and infrastructure of built environment. Urban areas are created through urbanization and are categorized by urban morphology as cities, towns, conurbations or suburbs. In urbanism, the term contrasts to rural areas such as villages and hamlets; in urban sociology or urban anthropology it contrasts with natural environment. The creation of earlier predecessors of urban areas during the urban revolution led to the creation of human civilization with modern urban planning, which along with other human activities such as exploitation of natural resources led to a human impact on the environment. "Agglomeration effects" are in the list of the main consequences of increased rates of firm creation since. This is due to conditions created by a greater level of industrial activity in a given region. However, a favorable environment for human capital development would also be genera ...

Rail Transport
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles ( rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port
A port is a maritime facility comprising one or more wharves or loading areas, where ships load and discharge cargo and passengers. Although usually situated on a sea coast or estuary, ports can also be found far inland, such as Hamburg, Manchester and Duluth; these access the sea via rivers or canals. Because of their roles as ports of entry for immigrants as well as soldiers in wartime, many port cities have experienced dramatic multi-ethnic and multicultural changes throughout their histories. Ports are extremely important to the global economy; 70% of global merchandise trade by value passes through a port. For this reason, ports are also often densely populated settlements that provide the labor for processing and handling goods and related services for the ports. Today by far the greatest growth in port development is in Asia, the continent with some of the world's largest and busiest ports, such as Singapore and the Chinese ports of Shanghai and Ningbo-Zhou ...
