Piracy
Piracy is an act of robbery or criminal violence by ship or boat-borne attackers upon another ship or a coastal area, typically with the goal of stealing cargo and other valuable goods. Those who conduct acts of piracy are called pirates, and vessels used for piracy are called pirate ships. The earliest documented instances of piracy were in the 14th century BC, when the Sea Peoples, a group of ocean raiders, attacked the ships of the Aegean civilization, Aegean and Mediterranean civilisations. Narrow channels which funnel shipping into predictable routes have long created opportunities for piracy, as well as for privateering and commerce raiding. Historic examples of such areas include the waters of Gibraltar, the Piracy in the Strait of Malacca, Strait of Malacca, Madagascar, the Piracy off the coast of Somalia, Gulf of Aden, and the English Channel, whose geographic structures facilitated pirate attacks. The term ''piracy'' generally refers to maritime piracy, although the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flag Of Edward England
A flag is a piece of textile, fabric (most often rectangular or quadrilateral) with a distinctive design and colours. It is used as a symbol, a signalling device, or for decoration. The term ''flag'' is also used to refer to the graphic design employed, and flags have evolved into a general tool for rudimentary signalling and identification, especially in environments where communication is challenging (such as the Maritime flag, maritime environment, where Flag semaphore, semaphore is used). Many flags fall into groups of similar designs called flag families. The study of flags is known as "vexillology" from the Latin , meaning "flag" or "banner". National flags are patriotic symbols with widely varied interpretations that often include strong military associations because of their original and ongoing use for that purpose. Flags are also used in messaging, advertising, or for decorative purposes. Some military units are called "flags" after their use of flags. A ''flag'' ( ...

Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or ~19.8% of the water on Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. Along its core, the Indian Ocean has some large marginal or regional seas such as the Arabian Sea, Laccadive Sea, Bay of Bengal, and Andaman Sea. Etymology The Indian Ocean has been known by its present name since at least 1515 when the Latin form ''Oceanus Orientalis Indicus'' ("Indian Eastern Ocean") is attested, named after Indian subcontinent, India, which projects into it. It was earlier known as the ''Eastern Ocean'', a term that was still in use during the mid-18th century (see map), as opposed to the ''Western Ocean'' (Atlantic Ocean, Atlantic) before the Pacific Ocean, Pacific was surmised. Conversely, Ming treasure voyages, Chinese explorers in the Indian Oce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radar
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. Th ...

Sound Cannon
A long-range acoustic device (LRAD) is an acoustic hailing device (AHD), sound cannon and sonic weapon developed by Genasys. It has been used as a method of crowd control, which has caused permanent hearing damage, having an extremely high decibel capacity (up to 160 dB measured at one meter from the device). Other uses have included for negotiations in siege situations to deal with piracy at sea; for mass notification during natural disasters or other emergencies; and by defense forces, including several navies. History In October 2000 the , an American guided missile destroyer, was bombed in a terrorist attack by al-Qaeda operatives, using a small boat packed with explosives. The naval personnel on Cole were unable to be sure that their messages could be heard by the approaching boat at a sufficient distance to possibly avert the attack. The ship was badly damaged, 17 U.S. Navy sailors killed and 37 injured. Following this attack, navies around the world made severa ...

Water Cannon
A water cannon is a device that shoots a high-velocity stream of water. Typically, a water cannon can deliver a large volume of water, often over dozens of meters. They are used in firefighting, large vehicle washing, riot control, and mining. Most water cannons fall under the category of a fire monitor. Firefighting Water cannons were first devised for use on fireboats. Extinguishing fires on boats and buildings near the water was much more difficult and dangerous before fireboats were invented. The first fireboat deployed in Los Angeles was commissioned on 1 August 1919. The first fireboat in New York City was ''Marine 1'', deployed 1 February 1891. There may have been other fireboats elsewhere even earlier. Fire trucks deliver water with much the same force and volume as water cannons, and have even been used in riot control situations, but are rarely referred to as water cannons outside this context. Riot control The first truck-mounted water cannon was used for riot c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Navy
A navy, naval force, or maritime force is the branch of a nation's armed forces principally designated for naval warfare, naval and amphibious warfare; namely, lake-borne, riverine, littoral zone, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface Naval ship, ships, amphibious warfare, amphibious ships, submarines, and seaborne naval aviation, aviation, as well as ancillary support, communications, training, and other fields. The strategic offensive role of a navy is Power projection, projection of force into areas beyond a country's shores (for example, to protect Sea lane, sea-lanes, deter or confront piracy, ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of the navy also may incorporate nuclear deterrence by use of submarine-launched ballistic missiles. Naval operations can be broa ...

International Waters
The terms international waters or transboundary waters apply where any of the following types of bodies of water (or their drainage basins) transcend international boundaries: oceans, large marine ecosystems, enclosed or semi-enclosed regional seas and estuaries, rivers, lakes, groundwater systems (aquifers), and wetlands. "International waters" is not a defined term in international law. It is an informal term, which sometimes refers to waters beyond the "territorial sea" of any country. In other words, "international waters" is sometimes used as an informal synonym for the more formal term high seas or, in Latin, ''mare liberum'' (meaning ''free sea''). International waters (high seas) do not belong to any state's jurisdiction, known under the doctrine of 'mare liberum'. States have the right to fishing, navigation, overflight, laying cables and pipelines, as well as scientific research. The Convention on the High Seas, signed in 1958, which has 63 signatories, defined "hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Justice
Justice, in its broadest sense, is the principle that people receive that which they deserve, with the interpretation of what then constitutes "deserving" being impacted upon by numerous fields, with many differing viewpoints and perspectives, including the concepts of moral correctness based on ethics, rationality, law, religion, equity and fairness. The state will sometimes endeavor to increase justice by operating courts and enforcing their rulings. Early theories of justice were set out by the Ancient Greek philosophers Plato in his work The Republic, and Aristotle in his Nicomachean Ethics. Advocates of divine command theory have said that justice issues from God. In the 1600s, philosophers such as John Locke said that justice derives from natural law. Social contract theory said that justice is derived from the mutual agreement of everyone. In the 1800s, utilitarian philosophers such as John Stuart Mill said that justice is based on the best outcomes for the gre ...

International Community
The international community is an imprecise phrase used in geopolitics and international relations to refer to a broad group of people and governments of the world. As a rhetorical term Aside from its use as a general descriptor, the term is typically used to imply the existence of a common point of view towards such matters as specific issues of human rights. It is sometimes used in calling for action to be taken against an enemy, e.g., action against perceived political repression in a target country. The term is also commonly used to imply legitimacy and consensus for a point of view on a disputed issue, e.g., to enhance the credibility of a majority vote in the United Nations General Assembly. Criticism Several prominent legal figures and authors have argued that the term is more often used to describe a small minority of states, and not literally all nations or states in the world. According to International Criminal Court jurist Victor P. Tsilonis, it refers to "the in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rocket Propelled Grenade
A rocket-propelled grenade (RPG) is a shoulder-fired missile weapon that launches rockets equipped with an explosive warhead. Most RPGs can be carried by an individual soldier, and are frequently used as anti-tank weapons. These warheads are affixed to a rocket motor which propels the RPG towards the target and they are stabilized in flight with fins. Some types of RPG are reloadable with new rocket-propelled grenades, while others are single-use. RPGs are generally loaded from the front. RPGs with high-explosive anti-tank (HEAT) warheads are very effective against lightly armored vehicles such as armored personnel carriers (APCs) and armored cars. However, modern, heavily-armored vehicles, such as upgraded APCs and main battle tanks, are generally too well-protected (with thick composite or reactive armor) to be penetrated by an RPG, unless less armored sections of the vehicle are exploited. Various warheads are also capable of causing secondary damage to vulnerable system ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grenade
A grenade is an explosive weapon typically thrown by hand (also called hand grenade), but can also refer to a shell (explosive projectile) shot from the muzzle of a rifle (as a rifle grenade) or a grenade launcher. A modern hand grenade generally consists of an explosive charge ("filler"), a detonator mechanism, an internal striker to trigger the detonator, and a safety lever secured by a cotter pin. The user removes the safety pin before throwing, and once the grenade leaves the hand the safety lever gets released, allowing the striker to trigger a primer that ignites a fuze (sometimes called the delay element), which burns down to the detonator and explodes the main charge. Grenades work by dispersing fragments (fragmentation grenades), shockwaves (high-explosive, anti-tank and stun grenades), chemical aerosols (smoke and gas grenades) or fire ( incendiary grenades). Fragmentation grenades ("frags") are probably the most common in modern armies, and when the word ''gren ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
