Loophole (firearm)
A loophole is a protected small opening, which allows a firearm to be aimed and discharged, while providing cover and concealment for the rifleman. To prevent detection, the rifle's muzzle should not protrude through the loophole, particularly at night to hide the muzzle flash. Arrowslit The precursor to the loophole for firearms was the arrowslit, which is a narrow aperture in a fortification for an archer to launch arrows or an arbalist to launch crossbow bolts. The earliest use of the arrowslit was alleged to have been by Archimedes during the siege of Syracuse in 214–212 BC. Arrowslits were used in ancient Greek warfare and by the military of ancient Rome. There was a reintroduction of arrowslits during the medieval warfare period at Dover Castle and Framlingham Castle in England and by Richard the Lionheart at Château Gaillard in France.

Firearm
A firearm is any type of gun designed to be readily carried and used by an individual. The term is legally defined further in different countries (see Legal definitions). The first firearms originated in 10th-century China, when bamboo tubes containing gunpowder and pellet projectiles were mounted on spears to make the portable fire lance, operable by a single person, which was later used effectively as a shock weapon in the Siege of De'an in 1132. In the 13th century, fire lance barrels were replaced with metal tubes and transformed into the metal-barreled hand cannon. The technology gradually spread throughout Eurasia during the 14th century. Older firearms typically used black powder as a propellant, but modern firearms use smokeless powder or other propellants. Most modern firearms (with the notable exception of smoothbore shotguns) have rifled barrels to impart spin to the projectile for improved flight stability. Modern firearms can be described by their caliber ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century. The English language, the Anglican Church, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Embrasure
An embrasure (or crenel or crenelle; sometimes called gunhole in the domain of gunpowder-era architecture) is the opening in a battlement between two raised solid portions (merlons). Alternatively, an embrasure can be a space hollowed out throughout the thickness of a wall by the establishment of a bay. This term designates the internal part of this space, relative to the closing device, door or window. In fortification this refers to the outward splay of a window or of an arrowslit on the inside. In ancient military engineering, embrasures were constructed in towers and walls, in particular between the merlons and the battle. A loophole, arrow loop or arrowslit passes through a solid wall, and thus forms an embrasure of shooting, allowing archer or gunner weapons to be fired out from the fortification while the firer remains under cover. This type of opening was flared inward - that is: the opening was very narrow on the outside, but wide on the inside, so that ...

Elephant Gun
An elephant gun is a large caliber gun, rifled or smoothbore, originally developed for use by big-game hunters for elephant and other large game. Elephant guns were black powder muzzle-loaders at first, then black powder express rifles, then later used smokeless powder cartridges. Early use As Europeans made inroads into Africa in the early 19th century, guns were developed to handle the very large game encountered. This was for self-protection, food gathering, and sport. The first guns were the simple muzzle-loading shotgun designs already used for birds and loaded with solid balls of lead for use on large game. Due to their ineffectiveness on the largest game (up to 35 shots being recorded by some writers for a single elephant), they soon developed into larger caliber black powder smoothbores. The caliber was still measured in bore or gauge—10, 8, 6, 4 bore, and 2 bore—or the guns were named by number of projectiles per pound. The projectiles were lead round balls or s ...

Counter-sniper Tactics
Counter-sniper tactics have evolved in sniper warfare to reduce the effectiveness of snipers. Reducing the risk of damage During the stalking phase of their attack, a sniper will, if time allows, try to identify high-value targets, such as senior officers or senior NCOs. They will do this by closely observing the behavior of the people in front of them. The intention is to identify who is in charge and then prepare to fire at them. It naturally follows that leaders should attempt to blend into the background by avoiding anything that distinguishes them from the most junior soldiers and attracts the interest of a sniper. In order to reduce a sniper's ability to damage the chain of command, doctrine and equipment need to prevent any observable "leadership" behaviors and signs. Insignia, e.g. rank insignia, should be subdued (i.e. dark or black as opposed to bright colors), camouflage colors on battledress, battledress identical for all ranks, military servants and rank-based luxurie ...

Sniping In France
A sniper is a military/paramilitary marksman who engages targets from positions of concealment or at distances exceeding the target's detection capabilities. Snipers generally have specialized training and are equipped with high-precision rifles and high-magnification optics, and often also serve as scouts/ observers feeding tactical information back to their units or command headquarters. In addition to long-range and high-grade marksmanship, military snipers are trained in a variety of special operation techniques: detection, stalking, target range estimation methods, camouflage, tracking, bushcraft, field craft, infiltration, special reconnaissance and observation, surveillance and target acquisition. Etymology The name "sniper" comes from the verb "to snipe", which originated in the 1770s among soldiers in British India in reference to shooting snipes, a wader that was considered an extremely challenging game bird for hunters due to its alertness, camouflaging color an ...

Canadian Expeditionary Force
The Canadian Expeditionary Force (CEF) was the expeditionary field force of Canada during the First World War. It was formed following Britain’s declaration of war on Germany on 15 August 1914, with an initial strength of one infantry division. The division subsequently fought at Ypres on the Western Front, with a newly raised second division reinforcing the committed units to form the Canadian Corps. The CEF and corps was eventually expanded to four infantry divisions, which were all committed to the fighting in France and Belgium along the Western Front. A fifth division was partially raised in 1917, but was broken up in 1918 and used as reinforcements following heavy casualties. Personnel Recruitment The Canadian Expeditionary Force was mostly volunteers; a bill allowing conscription was passed in August, 1917, but not enforced until call-ups began in January 1918 (''see'' Conscription Crisis of 1917). In all, 24,132 conscripts had been sent to France to take part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trench Warfare
Trench warfare is a type of land warfare using occupied lines largely comprising Trench#Military engineering, military trenches, in which troops are well-protected from the enemy's small arms fire and are substantially sheltered from artillery. Trench warfare became archetypically associated with World War I (1914–1918), when the Race to the Sea rapidly expanded trench use on the Western Front (World War I), Western Front starting in September 1914.. Trench warfare proliferated when a Weapons of World War I, revolution in firepower was not matched by similar advances in mobility (military), mobility, resulting in a grueling form of warfare in which the defender held the advantage. On the Western Front in 1914–1918, both sides constructed elaborate trench, underground, and dugout systems opposing each other along a front (military), front, protected from assault by barbed wire. The area between opposing trench lines (known as "no man's land") was fully exposed to artillery ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
First World War
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was List of wars and anthropogenic disasters by death toll, one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific Ocean, Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in Genocides in history (World War I through World War II), genocides within the Ottoman Empire and in the Spanish flu, 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising French Third Republic, France, Russia, and British Empire, Britain) and the Triple A ...
