Scaling Ladder
{{Unreferenced, date=May 2007 Escalade is the act of scaling defensive walls or ramparts with the aid of ladders. Escalade was a prominent feature of sieges in ancient and medieval warfare, and though it is no longer common in modern warfare, escalade technologies are still developed and used in certain tactical applications. Overview Escalade consists of attacking soldiers advancing to the base of a wall, setting ladders, and climbing to engage the defending forces. Though very simple and direct, it was also one of the most dangerous options available; escalade would generally be conducted in the face of arrow fire from the battlements, and the defenders would naturally attempt to push ladders away from the wall. Heated or incendiary substances such as boiling water, heated sand, and pitch-coated missiles were sometimes poured on attacking soldiers. This made it difficult for attackers to reach the top of the wall, and those that did would often quickly be overwhelmed b ...

Frontal Assault
The military tactic of frontal assault is a direct, full-force attack on the front line of an enemy force, rather than to the flanks or rear of the enemy. It allows for a quick and decisive victory, but at the cost of subjecting the attackers to the maximum defensive power of the enemy; this can make frontal assaults costly even if successful, and often disastrously costly if unsuccessful. It may be used as a last resort when time, terrain, limited command control, or low troop quality do not allow for any battlefield flexibility. The risks of a frontal assault can be mitigated by the use of heavy supporting fire, diversionary attacks, the use of cover (such as smokescreens or the darkness of night), or infiltration tactics. Frontal assaults were common in ancient warfare, where heavy infantry made up the core of armies such as the Greek phalanx and the Roman legion. These dense formations, many ranks deep, would utilize their weight in numbers to press forward and break enemy lin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siege Tactics
A siege is a military blockade of a city, or fortress, with the intent of conquering by attrition, or a well-prepared assault. This derives from la, sedere, lit=to sit. Siege warfare is a form of constant, low-intensity conflict characterized by one party holding a strong, static, defensive position. Consequently, an opportunity for negotiation between combatants is common, as proximity and fluctuating advantage can encourage diplomacy. The art of conducting and resisting sieges is called siege warfare, siegecraft, or poliorcetics. A siege occurs when an attacker encounters a city or fortress that cannot be easily taken by a quick assault, and which refuses to surrender. Sieges involve surrounding the target to block the provision of supplies and the reinforcement or escape of troops (a tactic known as "investment"). This is typically coupled with attempts to reduce the fortifications by means of siege engines, artillery bombardment, mining (also known as sapping), or the us ...

Savoy
Savoy (; frp, Savouè ; french: Savoie ) is a cultural-historical region in the Western Alps. Situated on the cultural boundary between Occitania and Piedmont, the area extends from Lake Geneva in the north to the Dauphiné in the south. Savoy emerged as the feudal County of Savoy ruled by the House of Savoy during the 11th to 14th centuries. The original territory, also known as "ducal Savoy" or "Savoy proper", is largely co-terminous with the modern French Savoie and Haute-Savoie ''départements'', but the historical expansion of Savoyard territories, as the Duchy of Savoy (1416–1860) included parts of what is now western Italy and southwestern Switzerland. The current border between France and Italy is due to the Plombières Agreement of 1858, which in preparation for the unification of Italy ceded western Savoy to France, while the eastern territories in Piedmont and Liguria were retained by the House of Savoy, which was to become the ruling dynasty of Italy. ...

L'Escalade
''L'Escalade'', or ''Fête de l'Escalade'' (from escalade, the act of scaling defensive walls), is an annual festival in Geneva, Switzerland, held each December commemorating the defeat of an attempt to conquer the Protestant city-state by the Catholic Duchy of Savoy in 1602. The celebrations and other commemorative activities are usually held on 12 December or the closest weekend. Savoyard troops sent by Charles Emmanuel I, Duke of Savoy attempted a surprise attack during the night of 11–12 December 1602, but were repulsed by the Genevese defenders. According to legend, this was possible thanks to individual acts of bravery by Genevese citizens, notably by local resident Catherine Cheynel (also known as ''la Mère Royaume''), who dumped boiling vegetable soup on the invaders and alerted the townsfolk. Background For years, the duke coveted the wealth of Geneva. When Charles Emmanuel came to the throne of the House of Savoy in 1580, he aimed to make Geneva his capital north ...

Siege Tower
A Roman siege tower or breaching tower (or in the Middle Ages, a belfry''Castle: Stephen Biesty's Cross-Sections''. Dorling Kindersley Pub (T); 1st American edition (September 1994). Siege towers were invented in 300 BC. ) is a specialized siege engine, constructed to protect assailants and ladders while approaching the defensive walls of a fortification. The tower was often rectangular with four wheels with its height roughly equal to that of the wall or sometimes higher to allow archers to stand on top of the tower and shoot arrows into the fortification. Because the towers were wooden and thus flammable, they had to have some non-flammable covering of iron or fresh animal skins. Used since the 11th century BC by the Babylonians and Assyrians in the ancient Near East, the 4th century BC in Europe and also in antiquity in the Far East, siege towers were of unwieldy dimensions and, like trebuchets, were therefore mostly constructed on site of the siege. Taking considerable time t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Balcony
A balcony (from it, balcone, "scaffold") is a platform projecting from the wall of a building, supported by columns or console brackets, and enclosed with a balustrade, usually above the ground floor. Types The traditional Maltese balcony is a wooden closed balcony projecting from a wall. By contrast, a Juliet balcony does not protrude out of the building. It is usually part of an upper floor, with a balustrade only at the front, like a small loggia. A modern Juliet balcony often involves a metal barrier placed in front of a high window that can be opened. In the UK, the technical name for one of these was officially changed in August 2020 to a ''Juliet guarding''. Juliet balconies are named after William Shakespeare's Juliet, who, in traditional stagings of the play '' Romeo and Juliet'', is courted by Romeo while she is on her balcony—though the play itself, as written, makes no mention of a balcony, but only of a window at which Juliet appears. Various types of balc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Window Sill
A windowsill (also written window sill or window-sill, and less frequently in British English, cill) is the horizontal structure or surface at the bottom of a window. Window sills serve to structurally support and hold the window in place. The exterior portion of a window sill provides a mechanism for shedding rainwater away from the wall at the window opening. Therefore, window sills are usually inclined slightly downward away from the window and wall, and often extend past the exterior face of the wall, so the water will drip off rather than run down the wall. Some windowsills are made of natural stone, cast stone, concrete, tile, or other non-porous materials to further increase their water resistance. Windows may not have a structural sill or the sill may not be sufficiently weather resistant. In these cases, a strip of waterproof and weather resistant material (steel, vinyl, PVC) called a sill pan may be used to protect the wall and shed the water. Like the sill, a sill ...

Special Forces
Special forces and special operations forces (SOF) are military units trained to conduct special operations. NATO has defined special operations as "military activities conducted by specially designated, organized, selected, trained and equipped forces using unconventional techniques and modes of employment". Special forces emerged in the early 20th century, with a significant growth in the field during the Second World War, when "every major army involved in the fighting" created formations devoted to special operations behind enemy lines. Depending on the country, special forces may perform functions including airborne operations, counter-insurgency, counter-terrorism, foreign internal defense, covert ops, direct action, hostage rescue, high-value targets/manhunt, intelligence operations, mobility operations, and unconventional warfare. In Russian-speaking countries, special forces of any country are typically called , an acronym for "special purpose". In the United ...

Counterterrorism
Counterterrorism (also spelled counter-terrorism), also known as anti-terrorism, incorporates the practices, military tactics, techniques, and strategies that governments, law enforcement, business, and intelligence agencies use to combat or eliminate terrorism. Counterterrorism strategies are a government's motivation to use the instruments of national power to defeat terrorists, the organizations they maintain, and the networks they contain. If definitions of terrorism are part of a broader insurgency, counterterrorism may employ counterinsurgency measures. The United States Armed Forces uses the term foreign internal defense for programs that support other countries' attempts to suppress insurgency, lawlessness, or subversion, or to reduce the conditions under which threats to national security may develop. History The first counter-terrorism body formed was the Special Irish Branch of the Metropolitan Police, later renamed the Special Branch after it expanded it ...

Police Tactical Unit
A police tactical unit (PTU) is a specialized police unit trained to handle situations that are beyond the capabilities of ordinary law enforcement units because of the level of violence (or risk of violence) involved. A police tactical unit's tasks may include executing search warrants and arrest warrants for dangerous suspects, arresting or neutralizing dangerous armed suspects, and intervening in high risk situations such as shootouts, hostage takings, and terrorist incidents. Definition Police tactical units are dedicated units composed of personnel selected and trained in tactical skillsets to carry out the responsibilities of the unit, including use of force, arrest procedures, close-quarters combat, door breaching, and counterterrorism. A PTU is equipped with specialized police and military-type equipment. PTU personnel may also be trained in crisis negotiation skills. A PTU can be part of either a police force under the authority of civilian officials; or a gendarme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
