Brest, Belarus
–
Brest formerly also Brześć nad Bugiem Brest-on-the-Bug and Brest-Litovsk, is a city in Belarus at the border with Poland opposite the Polish city of Terespol, where the Bug and Mukhavets rivers meet. It is the city of the Brest voblast. The city of Brest is a site of many cultures. It was the location of important historical events such as the Union of Brest, the Brest Fortress was recognized by the Soviet Union as the Hero Fortress in honor of the defense of Brest Fortress in June 1941. During medieval times, the city was part of the Kingdom of Poland from 1020 until 1319 when it was taken by the Grand Duchy of Lithuania and it became part of the Polish–Lithuanian Commonwealth in 1569. As a result of the Partitions of Poland, it was incorporated into the Russian Empire in 1795, after World War I, the city returned to Second Polish Republic. In 1941 it was again by the Nazis during Operation Barbarossa. After the war, once the new boundaries between the USSR and Poland were ratified, the city part of the Soviet BSSR until the breakup of the country in 1991. It is part of sovereign Belarus of today, several theories attempt to account for the origin of the citys name. It might have come from the Slavic root beresta meaning birch, the name of the city could also originate from the Slavic root berest meaning elm. And finally, the name of the city could have come from the Lithuanian word brasta meaning ford, once a center of Jewish scholarship, the city has the Yiddish name בריסק, hence the term Brisker used to describe followers of the influential Soloveitchik family of rabbis. The traditional Belarusian name for the city is Берасце, Brest became part of the Grand Duchy of Lithuania in 1319. In the Polish–Lithuanian Commonwealth formed in 1569 the town was known in Polish as Brześć, after World War I, and the rebirth of Poland, the government of the Second Polish Republic renamed the city as Brześć nad Bugiem on March 20,1923. After World War II the city part of Soviet Belarus with the name simplified as Brest. Brests coat of arms features an arrow pointed upwards and a bow on a sky-blue shield and it was adopted on January 26,1991. An alternative coat of arms has a red shield, Sigismund II Augustus, King of Poland and Grand Duke of Lithuania, first granted Brest a coat of arms in 1554. The city was founded by the Slavs, as a town, Brest – Berestye in Kievan Rus – was first mentioned in the Primary Chronicle in 1019 when the Kievan Rus took the stronghold from the Poles. It is one of the oldest cities in Belarus and it was hotly contested between the Polish rulers and Kievan Rus princes, laid waste by the Mongols in 1241, and was not rebuilt until 1275

Belarus
–
Its capital and most populous city is Minsk. Over 40% of its 207,600 square kilometres is forested and its strongest economic sectors are service industries and manufacturing. In the aftermath of the 1917 Russian Revolution, Belarus declared independence as the Belarusian Peoples Republic, the Socialist Soviet Republic of Byelorussia became a founding constituent republic of the Soviet Union in 1922 and was renamed as the Byelorussian Soviet Socialist Republic. Belarus lost almost half of its territory to Poland after the Polish–Soviet War of 1919–1921, during WWII, military operations devastated Belarus, which lost about a third of its population and more than half of its economic resources. The republic was redeveloped in the post-war years, in 1945 the Byelorussian SSR became a founding member of the United Nations, along with the Soviet Union and the Ukrainian SSR. The parliament of the declared the sovereignty of Belarus on 27 July 1990. Alexander Lukashenko has served as the president since 1994. Belarus has been labeled Europes last dictatorship by some Western journalists, Lukashenko continued a number of Soviet-era policies, such as state ownership of large sections of the economy. Though not directly espousing communism like the five remaining communist countries of China, Cuba, Laos, Vietnam and North Korea, in 2000 Belarus and Russia signed a treaty for greater cooperation, with some hints of forming a Union State. Over 70% of Belaruss population of 9.49 million resides in urban areas, more than 80% of the population is ethnic Belarusian, with sizable minorities of Russians, Poles and Ukrainians. Since a referendum in 1995, the country has had two official languages, Belarusian and Russian, the Constitution of Belarus does not declare any official religion, although the primary religion in the country is Eastern Orthodox Christianity. Belarus is the only European country to retain capital punishment in both law and practice, the name Belarus is closely related with the term Belaya Rus, i. e. White Rus. There are several claims to the origin of the name White Rus, an alternate explanation for the name comments on the white clothing worn by the local Slavic population. A third theory suggests that the old Rus lands that were not conquered by the Tatars had been referred to as white, other sources claim that, before 1267, the land not conquered by the Mongols was considered White Rus. The name Rus is often conflated with its Latin forms Russia and Ruthenia, in some languages, including German and Dutch, the country is generally called White Russia to this day. The Latin term Alba Russia was used again by Pope Pius VI in 1783 to recognize the Society of Jesus there, exclaiming Approbo Societatem Jesu in Alba Russia degentem, approbo, approbo. The first known use of White Russia to refer to Belarus was in the century by Englishman Sir Jerome Horsey. During the 17th century, the Russian tsars used White Rus to describe the lands added from the Grand Duchy of Lithuania

Border
–
Borders are geographic boundaries of political entities or legal jurisdictions, such as governments, sovereign states, federated states, and other subnational entities. Some borders—such as an internal administrative border, or inter-state borders within the Schengen Area—are often open. Other borders are partially or fully controlled, and may be crossed only at designated border checkpoints. Mostly contentious, borders may even foster the setting up of buffer zones, a difference has also been established in academic scholarship between border and frontier, the latter denoting a state of mind rather than state boundaries. In the past, many borders were not clearly defined lines, instead there were often intervening areas often claimed, a special case in recent times was the neutral zones that were set up along parts of Saudi Arabias borders with Kuwait and Iraq. In modern times, marchlands have been replaced by clearly defined and demarcated borders, for the purposes of border control, airports and seaports are also classed as borders. Most countries have some form of control to regulate or limit the movement of people, animals. Some borders require presentation of legal paperwork like passports and visas, or other identity documents, moving goods across a border often requires the payment of excise tax, often collected by customs officials. Animals moving across borders may need to go into quarantine to prevent the spread of infectious diseases. Most countries prohibit carrying illegal drugs or endangered animals across their borders, moving goods, animals, or people illegally across a border, without declaring them or seeking permission, or deliberately evading official inspection, constitutes smuggling. Controls on car liability insurance validity and other formalities may also take place, in places where smuggling, migration, and infiltration are a problem, many countries fortify borders with fences and barriers, and institute formal border control procedures. But some borders are merely signposted and this is common in countries within the European Schengen Area and on rural sections of the Canada–United States border. Borders may even be unmarked, typically in remote or forested regions. The frontiers were particularly porous for the movement of migrants. A border may have been, Agreed by the countries on both sides Imposed by the country on one side Imposed by third parties, e. g, in addition, a border may be a de facto military ceasefire line. Political borders are imposed on the world through human agency, political borders are often classified by whether or not they follow conspicuous physical features on the earth. Natural borders are geographical features that present natural obstacles to communication, existing political borders are often a formalization of these historical, natural obstacles. Some geographical features that often constitute natural borders are, Oceans, oceans create very costly natural borders, very few nation-states span more than one continent

Border guard
–
A border guard of a country is a national security agency that performs border control, i. e. enforces the security of the countrys national borders. Some of the border guard agencies also perform coast guard. In different countries, names of particular border guard services vary significantly, the service may be called police, guard, troops or sentinel and the name would refer to the nations official term for the state border - whether it is frontier or border. Most border guards of the world use dark green-colored elements on their uniform, patrols go out regularly from the Border outposts to patrol the international border to check illegal crossings and track any footprints of those who may have crossed over illegally or attempted to. The Border Guard may also perform delegated customs and immigration control duties, wartime assistance of the Border guard to the Army is essential as they are familiar with the local terrain having patrolled it on a daily basis during peacetime. During wars, Border outposts are reworked into well fortified dug-in positions from where regular Army units can operate to defend the integrity of the country. Border Guards Bangladesh is a border security and anti-smuggling force under the Ministry of Home Affairs of Bangladesh. BGB can trace back its origin to the establishment of the Ramgarh Local Battalion in 1795 and this force is lightly armed and although its primary duty is to protect the border, during national emergencies it can also be called upon to aid the government. Canada Border Services Agency is a law enforcement agency of the Department of Public Safety, created in 2003, it amalgamated the enforcement activities performed by three separate government entities. Traditionally unarmed, the arming of Border Services Officers, Investigators, Officers are found at entry points to Canada in some conflicts such as the Six Day War. Also, many border posts are staffed by Carabinieri, the Immigration and Border Police also performs border police duties. The State Border Guard Service is the charged with controlling and maintaining the Lithuanian Border. The State Border Guard Service falls under authority of the Ministry of the Interior, Border patrol and immigration control in Macau are conducted by Public Security Police Force of Macau at land entries with China and at Macau International Airport. Customs duties are performed by Macau Customs agency, both border guards and customs officers are responsibilities of the Secretariat for Security. Before the establishment of the agency, Malaysian borders was guarded by the Malaysian Armed Forces, the Royal Marechaussee is the fourth organization within the Dutch Royal Army, besides Army, Navy and Air Force. Besides patrolling the border it also has the function of Military Police, sometime thereafter, the Border Security Bureau was enlarged to corps level and renamed the Border Security Command. Previously headquartered in Chagang Province, the Border Security Command was relocated to P’yŏngyang in 2002, the Frontier Corps is a federal paramilitary force recruited mostly by people from the tribal areas and led by officers from the Pakistan Army. The FC is stationed in the Khyber-Pakhtunkhwa and Balochistan Province, are known as FC NWFP and FC Balochistan, the Pakistan Rangers are a paramilitary force under the control of the Ministry of the Interior of the Pakistani government

Radio
–
When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form, Radio systems need a transmitter to modulate some property of the energy produced to impress a signal on it, for example using amplitude modulation or angle modulation. Radio systems also need an antenna to convert electric currents into radio waves, an antenna can be used for both transmitting and receiving. The electrical resonance of tuned circuits in radios allow individual stations to be selected, the electromagnetic wave is intercepted by a tuned receiving antenna. Radio frequencies occupy the range from a 3 kHz to 300 GHz, a radio communication system sends signals by radio. The term radio is derived from the Latin word radius, meaning spoke of a wheel, beam of light, however, this invention would not be widely adopted. The switch to radio in place of wireless took place slowly and unevenly in the English-speaking world, the United States Navy would also play a role. Although its translation of the 1906 Berlin Convention used the terms wireless telegraph and wireless telegram, the term started to become preferred by the general public in the 1920s with the introduction of broadcasting. Radio systems used for communication have the following elements, with more than 100 years of development, each process is implemented by a wide range of methods, specialised for different communications purposes. Each system contains a transmitter, This consists of a source of electrical energy, the transmitter contains a system to modulate some property of the energy produced to impress a signal on it. This modulation might be as simple as turning the energy on and off, or altering more subtle such as amplitude, frequency, phase. Amplitude modulation of a carrier wave works by varying the strength of the signal in proportion to the information being sent. For example, changes in the strength can be used to reflect the sounds to be reproduced by a speaker. It was the used for the first audio radio transmissions. Frequency modulation varies the frequency of the carrier, the instantaneous frequency of the carrier is directly proportional to the instantaneous value of the input signal. FM has the capture effect whereby a receiver only receives the strongest signal, Digital data can be sent by shifting the carriers frequency among a set of discrete values, a technique known as frequency-shift keying. FM is commonly used at Very high frequency radio frequencies for high-fidelity broadcasts of music, analog TV sound is also broadcast using FM. Angle modulation alters the phase of the carrier wave to transmit a signal

International relations
–
International relations is an academic and a public policy field, and so can be positive and normative, because it analyzes and formulates the foreign policy of a given State. As political activity, international relations dates from the time of the Greek historian Thucydides, in practice International Relations and International Affairs forms a separate academic program or field from Political Science, and the courses taught therein are highly interdisciplinary. The history of international relations based on sovereign states is often traced back to the Peace of Westphalia of 1648, prior to this the European medieval organization of political authority was based on a vaguely hierarchical religious order. Contrary to popular belief, Westphalia still embodied layered systems of sovereignty, the centuries of roughly 1500 to 1789 saw the rise of the independent, sovereign states, the institutionalization of diplomacy and armies. The French Revolution added to this the new idea that not princes or an oligarchy, such a state in which the nation is sovereign would thence be termed a nation-state. The term republic increasingly became its synonym, the same claim to sovereignty was made for both forms of nation-state. The particular European system supposing the sovereign equality of states was exported to the Americas, Africa, and Asia via colonialism, the contemporary international system was finally established through decolonization during the Cold War. While the nation-state system is considered modern, many states have not incorporated the system and are termed pre-modern, further, a handful of states have moved beyond insistence on full sovereignty, and can be considered post-modern. The ability of contemporary IR discourse to explain the relations of different types of states is disputed. What is explicitly recognized as international relations theory was not developed until after World War I, IR theory, however, has a long tradition of drawing on the work of other social sciences. The use of capitalizations of the I and R in international relations aims to distinguish the academic discipline of international relations from the phenomena of international relations. Similarly, liberalism draws upon the work of Kant and Rousseau, in the 20th century, in addition to contemporary theories of liberal internationalism, Marxism has been a foundation of international relations. International relations as a field of study began in Britain. IR emerged as an academic discipline in 1919 with the founding of the first IR professorship. Georgetown Universitys Edmund A. Walsh School of Foreign Service is the oldest international relations faculty in the United States and this was rapidly followed by establishment of IR at universities in the US and in Geneva, Switzerland. The creation of the posts of Montague Burton Professor of International Relations at LSE, furthermore, the International History department at LSE developed a focus on the history of IR in the early modern, colonial and Cold War periods. The first university dedicated to the study of IR was the Graduate Institute of International Studies. The Committee on International Relations at the University of Chicago was the first to offer a graduate degree, in 2012, Ramon Llull University initiated the first International Relations degree in Barcelona, fully in English

Tent
–
A tent pronunciation is a shelter consisting of sheets of fabric or other material draped over, attached to a frame of poles or attached to a supporting rope. While smaller tents may be free-standing or attached to the ground, first used as portable homes by nomadic peoples, tents are now more often used for recreational camping and temporary shelters. Tents range in size from bivouac structures, just big enough for one person to sleep in, the bulk of this article is concerned with tents used for recreational camping which have sleeping space for one to ten people. Larger tents are discussed in a section below. Tents for recreational camping fall into two categories, Tents intended to be carried by backpackers are the smallest and lightest type. Small tents may be light that they can be carried for long distances on a touring bicycle. The second type are larger, heavier tents which are carried in a car or other vehicle. Depending on tent size and the experience of the person or people involved, Some very specialised tents have spring-loaded poles and can be pitched in seconds, but take somewhat longer to strike. Tents were used at least as far back as the early Iron Age and they are mentioned in the Bible, for example, in the Genesis 4,20 Jabal is described as the first to live in tents and raise sheep and goats. The Roman Army used leather tents, copies of which have been used successfully by modern reenactors, various styles developed over time, some derived from traditional nomadic tents, such as the yurt. Most military tents throughout history were of a ridge design. The major technological advance was the use of linen or hemp canvas for the canopy versus leather for the Romans, the primary use of tents was still to provide portable shelter for a small number of men in the field. By World War I larger designs were being deployed in areas to provide shelter for support activities and supplies. Tents are used as habitation by nomads, recreational campers, Tents are typically used as overhead shelter for festivals, weddings, backyard parties, and major corporate events. They are also used for covers, industrial shelters. Tents have traditionally used by nomadic people all over the world, such as Native Americans, Mongolian, Turkic and Tibetan Nomads. Armies all over the world have long used tents as part of their working life, Tents are preferred by the military for their relatively quick setup and take down times, compared to more traditional shelters. One of the worlds largest users of tents is the U. S. Department of Defense, the U. S. Department of Defense has strict rules on tent quality and tent specifications

Arsenal
–
An arsenal is a place where arms and ammunition are made, maintained and repaired, stored, or issued, in any combination, whether privately or publicly owned. Arsenal and armoury or armory are mostly regarded as synonyms, although differences in usage exist. A sub-armory is a place of storage or carrying of weapons and ammunition. From Italian, arsenale, and French, arsenal, from Arabic, دار تعبئة, dār a-tabiya, in a second-class arsenal, the factories would be replaced by workshops. The situation of an arsenal should be governed by strategic considerations. If of the first class, it should be situated at the base of operations and supply, secure from attack, not too near a frontier, the importance of a large arsenal is such that its defences would be on the scale of those of a large fortress. The usual subdivision of branches in a great arsenal is into storekeeping, under construction, Gun factory, carriage factory, laboratory, small-arms factory, harness and tent factory, powder factory, etc. In a second-class arsenal there would be instead of these factories. Frederick Taylor introduced command and control techniques to arsenals, including the U. S. s Watertown Arsenal, armorer Dresden Armory Halifax Armoury Harpers Ferry Armory Kremlin Armoury Royal Arsenal Royal Armouries Springfield Armory Zeughaus Magazine

Trench
–
A trench is a type of excavation or depression in the ground that is generally deeper than it is wide, and narrow compared with its length. In geology, trenches are created as a result of erosion by rivers or by geological movement of tectonic plates, in the civil engineering field, trenches are often created to install underground infrastructure or utilities, or later to access these installations. Trenches have also often been dug for defensive purposes. In archaeology, the method is used for searching and excavating ancient ruins or to dig into strata of sedimented material. Some trenches are created as a result of erosion by running water or by glaciers, others, such as rift valleys or more commonly oceanic trenches, are created by geological movement of tectonic plates. Some oceanic trenches include the Mariana Trench and the Aleutian Trench, the former geoform is relatively deep, linear and narrow, and is formed by plate subduction when plates converge. In the civil engineering field of construction or maintenance of infrastructure and they are used to place underground easily damaged and obstructive infrastructure or utilities. A similar use for higher bulk would be in pipeline transport and they may also be created later to search for pipes and other infrastructure that is known to be underground in the general area, but whose exact location has been lost. Finally, trenches may be created as the first step of creating a foundation wall, Trench shoring is often used in trenchworks to protect workers and stabilise embankments. An alternative to digging trenches is to create a utility tunnel, the advantages of utility tunnels are the reduction of maintenance manholes, one-time relocation, and less excavation and repair, compared with separate cable ducts for each service. When they are well mapped, they also allow access to all utilities without having to dig access trenches or resort to confused. One of the greatest advantages is public safety, for a comparison of utility tunnels vs. direct burial, see the article referred to above. In some cases, a trench is dug and deliberately preserved. This is typically done to install depressed motorways, open railway cuttings, trenches have often been dug for defensive purposes. In the pre-firearm eras, they were mainly a type of hindrance to an attacker of a fortified location, an early example of this can be seen in the Battle of the Trench, one of the early Battles of the Islamic Prophet Muhammad. With the advent of firearms, trenches were used to shelter troops. The advantage of this method is that it only a small part of the site. However, this also has the disadvantage of only revealing small slices of the whole volume

Bunker
–
A bunker is a defensive military fortification designed to protect people or valued materials from falling bombs or other attacks. Bunkers are mostly underground, compared to blockhouses which are mostly above ground and they were used extensively in World War I, World War II, and the Cold War for weapons facilities, command and control centers, and storage facilities. Bunkers can also be used as protection from tornadoes, trench bunkers are small concrete structures, partly dug into the ground. Many artillery installations, especially for coastal artillery, have historically been protected by extensive bunker systems, typical industrial bunkers include mining sites, food storage areas, dumps for materials, data storage, and sometimes living quarters. When a house is purpose-built with a bunker, the location is a reinforced below-ground bathroom with fibre-reinforced plastic shells. Bunkers deflect the blast wave from nearby explosions to prevent ear, nuclear bunkers must also cope with the underpressure that lasts for several seconds after the shock wave passes, and block radiation. A bunkers door must be at least as strong as the walls, in bunkers inhabited for prolonged periods, large amounts of ventilation or air conditioning must be provided. Bunkers can be destroyed with explosives and bunker-busting warheads. The word bunker originates as a Scots word for bench, seat, the word possibly has a Scandinavian origin, Old Swedish bunke means boards used to protect the cargo of a ship. A sense of earthen seat is recorded 1805, with the spelling boncure from whence the use to refer to sand traps in golf, all the early references to its usage in the Oxford English Dictionary are to German fortifications. This type of bunker is a concrete structure, partly dug into the ground. Such bunkers give the defending soldiers better protection than the open trench and they also provide shelter against the weather. The front bunker of a system usually includes machine guns or mortars. The rear bunkers are usually used as posts or Tactical Operations Centers, for storage. Many artillery installations, especially for coastal artillery, have historically been protected by extensive bunker systems, artillery bunkers are some of the largest individual pre-Cold War bunkers. The walls of the Batterie Todt gun installation in northern France were up to 3.5 m thick, typical industrial bunkers include mining sites, food storage areas, dumps for materials, data storage, and sometimes living quarters. They were built mainly by nations like Germany during World War II to protect important industries from aerial bombardment, industrial bunkers are also built for control rooms of dangerous activities, e. g. tests of rocket engines or explosive experiments. They are also built in order to perform experiments in them or to store radioactive or explosive goods

Machine gun
–
A machine gun is a fully automatic mounted or portable firearm designed to fire bullets in quick succession from an ammunition belt or magazine, typically at a rate of 300 to 1800 rounds per minute. Note that not all fully automatic firearms are machine guns, submachine guns, rifles, assault rifles, shotguns, pistols or cannons may be capable of fully automatic fire, but are not designed for sustained fire. Many machine guns also use belt feeding and open bolt operation, unlike semi-automatic firearms, which require one trigger pull per round fired, a machine gun is designed to fire for as long as the trigger is held down. Nowadays the term is restricted to heavy weapons, able to provide continuous or frequent bursts of automatic fire for as long as ammunition lasts. Machine guns are used against personnel, aircraft and light vehicles, or to provide suppressive fire. Some machine guns have in practice sustained fire almost continuously for hours, because they become very hot, practically all machine guns fire from an open bolt, to permit air cooling from the breech between bursts. They also usually have either a barrel cooling system, slow-heating heavyweight barrel, although subdivided into light, medium, heavy or general-purpose, even the lightest machine guns tend to be substantially larger and heavier than standard infantry arms. Medium and heavy guns are either mounted on a tripod or on a vehicle, when carried on foot. Medium machine guns use full-sized rifle rounds and are designed to be used from fixed positions mounted on a tripod. 50in, the M249 automatic rifle is operated by an automatic rifleman, but its ammunition may be carried by other Soldiers within the squad or unit. The M249 machine gun is a crew-served weapon, Machine guns usually have simple iron sights, though the use of optics is becoming more common. Many heavy machine guns, such as the Browning M2.50 caliber machine gun, are enough to engage targets at great distances. During the Vietnam War, Carlos Hathcock set the record for a shot at 7382 ft with a.50 caliber heavy machine gun he had equipped with a telescopic sight. This led to the introduction of.50 caliber anti-materiel sniper rifles, selective fire rifles firing a full-power rifle cartridge from a closed bolt are called automatic rifles or battle rifles, while rifles that fire an intermediate cartridge are called assault rifles. Unlocking and removing the spent case from the chamber and ejecting it out of the weapon as bolt is moving rearward Loading the next round into the firing chamber. Usually the recoil spring tension pushes bolt back into battery and a cam strips the new round from a feeding device, cycle is repeated as long as the trigger is activated by operator. Releasing the trigger resets the trigger mechanism by engaging a sear so the weapon stops firing with bolt carrier fully at the rear, the operation is basically the same for all autoloading firearms, regardless of the means of activating these mechanisms. Most modern machine guns use gas-operated reloading, a recoil actuated machine gun uses the recoil to first unlock and then operate the action. Machine guns such as the M2 Browning and MG42, are of this type, a cam, lever or actuator demultiplicates the energy of the recoil to operate the bolt

Watchtower
–
A watchtower, or watch tower, is a type of fortification used in many parts of the world. It differs from a tower in that its primary use is military. Its main purpose is to provide a high, safe place from which a sentinel or guard may observe the surrounding area, in some cases, non-military towers, such as religious pagodas, may also be used as watchtowers. The Romans built numerous towers as part of a system of communications, in medieval Europe, many castles and manor houses, or similar fortified buildings, were equipped with watchtowers. In some of the houses of western France, the watchtower equipped with arrow or gun loopholes was one of the principal means of defense. A feudal lord could keep watch over his domain from the top of his tower, in southern Saudi Arabia and Yemen, small stone and mud towers called qasaba were constructed as either watchtowers or keeps in the Asir mountains. Furthermore, in Najd, a watchtower, called Margab, was used to watch for approaching enemies far in distance and shout calling warnings from atop. Scotland saw the construction of Peel towers that combined the function of watchtower with that of a keep or tower house served as the residence for a local notable family. Later many were restored or built against the Barbary pirates, some notable examples of military Mediterranean watchtowers include the towers that the Knights of Malta had constructed on the coasts of Malta. These towers ranged in size from small watchtowers to large structures armed with numerous cannons and they include the Wignacourt, de Redin, and Lascaris towers, named for the Grand Master, such as Martin de Redin, that commissioned each series. In the Channel Islands, the Jersey Round Towers and the Guernsey loophole towers date from the late 18th Century and they were erected to give warning of attacks by the French. One of the last Martello towers to be built was Fort Denison in Sydney harbour, the most recent descendants of the Martello Towers are the flak towers that the various combatants erected in World War II as mounts for anti-aircraft artillery. An example of nonmilitary watchtower in history is the one of Jerusalem, though the Hebrews used it to keep a watch for approaching armies, the religious authorities forbade the taking of weapons up into the tower as this would require bringing weapons through the temple. Rebuilt by King Herod, that watchtower was renamed after Mark Antony, his friend who battled against Gaius Julius Caesar Octavianus, fire lookout tower Observation towers are similar constructions being usually outside of fortifications. A similar use have also Control towers on airports or harbours, diaolou Watchtower Media related to Watch towers at Wikimedia Commons
