Artillery Battery
In military organizations, an artillery battery is a unit or multiple systems of artillery, mortar systems, rocket artillery, multiple rocket launchers, surface-to-surface missiles, ballistic missiles, cruise missiles, etc., so grouped to facilitate better battlefield communication and command and control, as well as to provide dispersion for its constituent gunnery crews and their systems. The term is also used in a naval context to describe groups of guns on warships. Land usage Historically the term "battery" referred to a cluster of cannon in action as a group, either in a temporary field position during a battle or at the siege of a fortress or a city. Such batteries could be a mixture of cannon, howitzer, or mortar types. A siege could involve many batteries at different sites around the besieged place. The term also came to be used for a group of cannon in a fixed fortification, for coastal or frontier defence. During the 18th century "battery" began to be used a ...

Youghal Battery
Youghal ( ; ) is a seaside resort town in County Cork, Ireland. Located on the estuary of the River Blackwater, the town is a former military and economic centre. Located on the edge of a steep riverbank, the town has a long and narrow layout. As of the 2016 census, the population was 7,963. As a historic walled seaport town on the coastline of East Cork, and close to a number of beaches, it has been a tourist destination since the mid-19th century. There are a number of historic buildings and monuments within the town's walls, and Youghal is among a small number of towns designated as "Irish Heritage Ports" by the Irish Tourist Board. Name The name ''Youghal'' comes from the Irish ''Eochaill'' meaning " yew woods", which were once common in the area. Older anglicisations of this name include ''Youghall'', ''Yoghel'' and ''Yochil''.

6 (six) is the natural number following 5 and preceding 7. It is a composite number and the smallest perfect number. In mathematics Six is the smallest positive integer which is neither a square number nor a prime number; it is the second smallest composite number, behind 4; its proper divisors are , and . Since 6 equals the sum of its proper divisors, it is a perfect number; 6 is the smallest of the perfect numbers. It is also the smallest Granville number, or \mathcal-perfect number. As a perfect number: *6 is related to the Mersenne prime 3, since . (The next perfect number is 28.) *6 is the only even perfect number that is not the sum of successive odd cubes. *6 is the root of the 6-aliquot tree, and is itself the aliquot sum of only one other number; the square number, . Six is the only number that is both the sum and the product of three consecutive positive numbers. Unrelated to 6's being a perfect number, a Golomb ruler of length 6 is a "perfect ruler". Six is a c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Civil War
The American Civil War (April 12, 1861 – May 26, 1865; also known by Names of the American Civil War, other names) was a civil war in the United States. It was fought between the Union (American Civil War), Union ("the North") and the Confederate States of America, Confederacy ("the South"), the latter formed by U.S. state, states that had secession, seceded. The central Origins of the American Civil War, cause of the war was the dispute over whether Slavery in the United States, slavery would be permitted to expand into the western territories, leading to more slave states, or be prevented from doing so, which was widely believed would place slavery on a course of ultimate extinction. Timeline of events leading to the American Civil War, Decades of political controversy over slavery were brought to a head by the victory in the 1860 United States presidential election, 1860 U.S. presidential election of Abraham Lincoln, who opposed slavery's expansion into the west. ...

Mule
The mule is a domestic equine hybrid between a donkey and a horse. It is the offspring of a male donkey (a jack) and a female horse (a mare). The horse and the donkey are different species, with different numbers of chromosomes; of the two possible first-generation hybrids between them, the mule is easier to obtain and more common than the hinny, which is the offspring of a female donkey (a jenny) and a male horse (a stallion). Mules vary widely in size, and may be of any color. They are more patient, hardier and longer-lived than horses, and are perceived as less obstinate and more intelligent than donkeys. Terminology A female mule that has oestrus cycles, and which could thus in theory carry a foetus, is called a "molly" or "Molly mule", though the term is sometimes used to refer to female mules in general. A male mule is properly called a "horse mule", though often called a "john mule", which is the correct term for a gelded mule. A young male mule is called a "mule ...

Ammunition Line
Ammunition (informally ammo) is the material fired, scattered, dropped, or detonated from any weapon or weapon system. Ammunition is both expendable weapons (e.g., bombs, missiles, grenades, land mines) and the component parts of other weapons that create the effect on a target (e.g., bullets and Warhead, warheads). The purpose of ammunition is to project a force against a selected Targeting (warfare), target to have an effect (usually, but not always, lethal). An example of ammunition is the firearm Cartridge (firearms), cartridge, which includes all components required to deliver the weapon effect in a single package. Until the 20th century, black powder was the most common propellant used but has now been replaced in nearly all cases by modern compounds. Ammunition comes in a great range of sizes and types and is often designed to work only in specific weapons systems. However, there are internationally recognized standards for certain ammunition types (e.g., 5.56×45mm N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gun Line
A gun is a ranged weapon designed to use a shooting tube (gun barrel) to launch projectiles. The projectiles are typically solid, but can also be pressurized liquid (e.g. in water guns/cannons, spray guns for painting or pressure washing, projected water disruptors, and technically also flamethrowers), gas (e.g. light-gas gun) or even charged particles (e.g. plasma gun). Solid projectiles may be free-flying (as with bullets and artillery shells) or tethered (as with Taser guns, spearguns and harpoon guns). A large-caliber gun is also called a ''cannon''. The means of projectile propulsion vary according to designs, but are traditionally effected pneumatically by a high gas pressure contained within the barrel tube, produced either through the rapid exothermic combustion of propellants (as with firearms), or by mechanical compression (as with air guns). The high-pressure gas is introduced behind the projectile, pushing and accelerating it down the length of the tube, imparti ...

Shore Defence Sector
A shore or a shoreline is the fringe of land at the edge of a large body of water, such as an ocean, sea, or lake. In physical oceanography, a shore is the wider fringe that is geologically modified by the action of the body of water past and present, while the beach is at the edge of the shore, representing the intertidal zone where there is one. In contrast to a coast, a shore can border any body of water, while the coast must border an ocean or a sea. Therefore, in that sense, a coast is a type of shore. However, the word "coast" often refers to an area far wider than the shore, often stretching miles into the interior. Shores are influenced by the topography of the surrounding landscape, as well as by water induced erosion, such as Wind wave, waves. The geology, geological composition of Rock (geology), rock and soil dictates the type of shore which is created. Rivieras ''Riviera'' is an Italian word for "shoreline", ultimately derived from Latin ''ripa'' ("riverbank"). ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coastal Artillery
Coastal artillery is the branch of the armed forces concerned with operating anti-ship artillery or fixed gun batteries in coastal fortifications. From the Middle Ages until World War II, coastal artillery and naval artillery in the form of cannons were highly important to military affairs and generally represented the areas of highest technology and capital cost among materiel. The advent of 20th-century technologies, especially military aviation, naval aviation, jet aircraft, and guided missiles, reduced the primacy of cannons, battleships, and coastal artillery. In countries where coastal artillery has not been disbanded, these forces have acquired amphibious capabilities. In littoral warfare, mobile coastal artillery armed with surface-to-surface missiles can still be used to deny the use of sea lanes. It was long held as a rule of thumb that one shore-based gun equaled three naval guns of the same caliber, due to the steadiness of the coastal gun which allo ...

Combined Arms
Combined arms is an approach to warfare that seeks to integrate different combat arms of a military to achieve mutually complementary effects (for example by using infantry and armour in an urban environment in which each supports the other). According to the strategist William S. Lind, combined arms can be distinguished from the concept of "supporting arms" as follows: Combined arms hits the enemy with two or more arms simultaneously in such a manner that the actions he must take to defend himself from one make him more vulnerable to another. In contrast, supporting arms is hitting the enemy with two or more arms in sequence, or if simultaneously, then in such combination that the actions the enemy must take to defend himself from one also defends himself from the other(s). Though the lower-echelon units of a combined arms team may be of similar types, a balanced mixture of such units are combined into an effective higher-echelon unit, whether formally in a table of organiz ...

Brigade
A brigade is a major tactical military formation that typically comprises three to six battalions plus supporting elements. It is roughly equivalent to an enlarged or reinforced regiment. Two or more brigades may constitute a division. Brigades formed into divisions are usually infantry or armored (sometimes referred to as combined arms brigades). In addition to combat units, they may include combat support units or sub-units, such as artillery and engineers, and logistic units. Historically, such brigades have sometimes been called brigade-groups. On operations, a brigade may comprise both organic elements and attached elements, including some temporarily attached for a specific task. Brigades may also be specialized and comprise battalions of a single branch, for example cavalry, mechanized, armored, artillery, air defence, aviation, engineers, signals or logistic. Some brigades are classified as independent or separate and operate independently from the traditional d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regiment
A regiment is a military unit. Its role and size varies markedly, depending on the country, service and/or a specialisation. In Medieval Europe, the term "regiment" denoted any large body of front-line soldiers, recruited or conscripted in one geographical area, by a leader who was often also the feudal lord ''in capite'' of the soldiers. Lesser barons of knightly rank could be expected to muster or hire a company or battalion from their manorial estate. By the end of the 17th century, infantry regiments in most European armies were permanent units, with approximately 800 men and commanded by a colonel. Definitions During the modern era, the word "regiment" – much like " corps" – may have two somewhat divergent meanings, which refer to two distinct roles: # a front-line military formation; or # an administrative or ceremonial unit. In many armies, the first role has been assumed by independent battalions, battlegroups, task forces, brigades and other, si ...

Squadron (army)
A squadron was historically a cavalry subunit, a company or battalion-sized military formation. The term is still used to refer to modern cavalry units, and is also used by other arms and services (frequently aviation, also naval). In some countries, including Italy, the name of the battalion-level cavalry unit translates as "''Squadron Group''". United States In the modern United States Army, a squadron is an armored cavalry, air cavalry, or other reconnaissance unit whose organizational role parallels that of a battalion and is commanded by a lieutenant colonel. Prior to the revisions in the US Army structure in the 1880s, US Cavalry regiments were divided into companies, and the battalion was an administrative designation used only in garrison. The reorganizations converted companies to troops and battalions to squadrons, and made squadrons tactical formations as well as administrative ones.
