Military Communications
Military communications or military signals involve all aspects of communications, or conveyance of information, by armed forces. Examples from '' Jane's Military Communications'' include text, audio, facsimile, tactical ground-based communications, naval signalling, terrestrial microwave, tropospheric scatter, satellite communications systems and equipment, surveillance and signal analysis, security, direction finding and jamming. IHS Jane'sbr>Military Communications Retrieved 2012-01-23. The most urgent purposes are to communicate information to commanders and orders from them. Military communications span from pre-history to the present. The earliest military communications were delivered by runners. Later, communications progressed to visual signals. For example, Naval ships would use flag signaling to communicate from ship to ship. These flags are a uniform set of easily identifiable nautical codes that would convey visual messages and codes between ships and fro ...

3 Men Working On A Portable Phone Switchboard
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious and cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th ...

Jane's
Janes is a global open-source intelligence company specialising in military, national security, aerospace and transport topics, whose name derives from British author Fred T. Jane. History Jane's Information Group was founded in 1898 by Fred T. Jane, who had begun sketching ships as an enthusiast naval artist while living in Portsmouth. This gradually developed into an encyclopedic knowledge, culminating in the publishing of ''All the World's Fighting Ships'' (1898). The company then gradually branched out into other areas of military expertise. The books and trade magazines published by the company are often considered the ''de facto'' public source of information on warfare and transportation systems. Based in Greater London for most of its existence, the group was owned by the Thomson Corporation, the Woodbridge Company, then IHS Markit, before being acquired by Montagu Private Equity in 2019. In March 2022, Janes acquired Washington, D.C.-based RWR Advisory Group. Desc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Informational Society
An information society is a society or subculture where the usage, creation, distribution, manipulation and integration of information is a significant activity. Its main drivers are information and communication technologies, which have resulted in rapid growth of a variety of forms of information. Proponents of this theory posit that these technologies are impacting most important forms of social organization, including education, economy, health, government, warfare, and levels of democracy. The people who are able to partake in this form of society are sometimes called either computer users or even digital citizens, defined by K. Mossberger as “Those who use the Internet regularly and effectively”. This is one of many dozen internet terms that have been identified to suggest that humans are entering a new and different phase of society. Some of the markers of this steady change may be technological, economic, occupational, spatial, cultural, or a combination of all o ...

Weapons
A weapon, arm, or armament is any implement or device that is used to deter, threaten, inflict physical damage, harm, or kill. Weapons are used to increase the efficacy and efficiency of activities such as hunting, crime (e.g., murder), law enforcement, self-defense, warfare, or suicide. In a broader context, weapons may be construed to include anything used to gain a tactical, strategic, material, or mental advantage over an adversary or enemy target. While ordinary objects such as rocks and bottles can be used as weapons, many objects are expressly designed for the purpose; these range from simple implements such as clubs and swords to complicated modern firearms, tanks, missiles and biological weapons. Something that has been repurposed, converted, or enhanced to become a weapon of war is termed ''weaponized'', such as a weaponized virus or weaponized laser. History The use of weapons has been a major driver of cultural evolution and human history up to toda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Civilian
A civilian is a person who is not a member of an armed force. It is war crime, illegal under the law of armed conflict to target civilians with military attacks, along with numerous other considerations for civilians during times of war. If a civilian engages in hostilities, they are an unlawful combatant and temporarily lose their protection from attack. It is slightly different from a non-combatant, because some non-combatants are not civilians (for example, people who are not in a military but support war effort or military operations, military chaplains, or military personnel who are serving with a neutral country). Civilians in the territories of a party to an armed conflict are entitled to certain privileges under the customary international law, customary laws of war and Treaty, international treaties such as the Fourth Geneva Convention. The privileges that they enjoy under international law depends on whether the conflict is an internal one (a civil war) or an internationa ...

Signaller
A signaller, signalman, colloquially referred to as a radioman or signaleer in the armed forces is a specialist soldier, sailor or airman responsible for military communications. Signallers, a.k.a. Combat Signallers or signalmen or women, are commonly employed as radio or telephone operators, relaying messages for field commanders at the front line (Army units, Ships or Aircraft), through a Command hierarchy, chain of command which includes field headquarters. Messages are transmitted and received via a communications infrastructure comprising fixed and mobile installations. Duties In the past, signalling skills have included the use of: Heliograph, Aldis lamp, Flag semaphore, semaphore flags, "Don R" (Dispatch Riders) and even Homing pigeon, carrier pigeons. Modern signallers are responsible for the battlefield voice and data communication and information technology infrastructure or in common English terms, they may carry a backpack radio transceiver used to communicate to ...

Cursus Publicus
The ''cursus publicus'' (Latin language, Latin: "the public way"; , ''dēmósios drómos'') was the state mandated and supervised courier and transportation service of the Roman Empire, the use of which continued into the Eastern Roman Empire and the Ostrogothic Kingdom. It was a system based on obligations placed on private persons by the Roman State. As contractors, called ''mancipes'', they provided the equipment, animals, and wagons. In the Early Empire compensation had to be paid but this had fallen into abeyance in Late Antiquity when maintenance was charged to the inhabitants along the routes. The service contained only those personnel necessary for administration and operation. These included veterinarians, wagon-wrights, and grooms. The couriers and wagon drivers did not belong to the service: whether public servants or private individuals, they used facilities requisitioned from local individuals and communities. The costs in Late Antiquity were charged to the provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
