Sorty
A sortie (from the French word meaning wikt:sortie, ''exit'' or from Latin root ''surgere'' meaning to "rise up") is a deployment or dispatch of one military unit, be it an aircraft, ship, or troops, from a strongpoint. The term originated in siege warfare. In aviation In military aviation, a sortie is a combat mission of an individual aircraft, starting when the aircraft takes off. For example, one mission involving six aircraft would tally six sorties. The sortie rate is the number of sorties that a given unit can support in a given time. In siege warfare In siege warfare, the word ''sortie'' refers specifically to a sudden issuing of troops against the enemy from a defensive position—that is, an attack launched against the besiegers by the defenders. If the sortie is through a sally port, the verb ''to sally'' may be used interchangeably with ''to sortie''. Purposes of sorties include harassment of enemy troops, destruction of siege weaponry and engineering works, joining ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aircraft
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called '' aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ...

Ship
A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. After the 15th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion dead weight tons. Of these 28% were oil tankers, 43% were bulk carriers, and ...

Strongpoint
In military tactics, a strongpoint is a key point in a defensive fighting position which anchors the overall defense line. This may include redoubts, bunkers, pillboxes, trenches or fortresses, alone or in combination; the primary requirement is that it should not be easily overrun or avoided. A blocking position in good defensive terrain commanding the lines of communication, such as high ground, is preferred. Examples from history include Thermopylae, where the ancient Greeks held back a much larger Persian army, and Monte Cassino, which anchored the Winter Line in Italy in World War II World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposin ....

Siege Warfare
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 use ...
