Close air supportIn military tactics, close air support (CAS) is defined as aerial warfare actions—often air-to-ground actions such as strafes or airstrikes—by military aircraft against hostile targets in close proximity to friendly forces. A form of fire support, CAS requires detailed integration of each air mission with fire and movement of all forces involved. CAS may be conducted using aerial bombs, glide bombs, missiles, rockets, autocannons, machine guns, and even directed-energy weapons such as lasers.
Military operationA military operation is the coordinated military actions of a state, or a non-state actor, in response to a developing situation. These actions are designed as a military plan to resolve the situation in the state or actor's favor. Operations may be of a combat or non-combat nature and may be referred to by a code name for the purpose of national security. Military operations are often known for their more generally accepted common usage names than their actual operational objectives.
Flanking maneuverIn military tactics, a flanking maneuver is a movement of an armed force around an enemy force's side, or flank, to achieve an advantageous position over it. Flanking is useful because a force's fighting strength is typically concentrated in its front, therefore, to circumvent an opposing force's front and attack its flank is to concentrate one's own offense in the area where the enemy is least able to concentrate defense. Flanking can also occur at the operational and strategic levels of warfare.
Military strategyMilitary strategy is a set of ideas implemented by military organizations to pursue desired strategic goals. Derived from the Greek word strategos, the term strategy, when first used during the 18th century, was seen in its narrow sense as the "art of the general", or "the art of arrangement" of troops. and deals with the planning and conduct of campaigns, the movement and disposition of forces, and the deception of the enemy. The father of Western modern strategic studies, Carl von Clausewitz (1780–1831), defined military strategy as "the employment of battles to gain the end of war.
SiegeA siege is a military blockade of a city, or fortress, with the intent of conquering by attrition, or by well-prepared assault. This derives from sedere. 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. A siege is conducted (by the attacking force) by siegecraft, or poliorcetics.
World War IWorld War I or the First World War, often abbreviated as WWI or WW1, known contemporaneously as the Great War, was a major global conflict lasting from 1914 to 1918. It was fought between two coalitions, the Allies and the Central Powers. Fighting took place throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. The first decade of the 20th century saw increasing diplomatic tension between the European great powers.
Operational level of warIn the field of military theory, the operational level of war (also called operational art, as derived from оперативное искусство, or operational warfare) represents the level of command that connects the details of tactics with the goals of strategy. In Joint U.S. military doctrine, operational art is "the cognitive approach by commanders and staffs—supported by their skill, knowledge, experience, creativity, and judgment—to develop strategies, campaigns, and operations to organize and employ military forces by integrating ends, ways, and means.
Offensive (military)An offensive is a military operation that seeks through an aggressive projection of armed forces to occupy or recapture territory, gain an objective or achieve some larger strategic, operational, or tactical goal. Another term for an offensive often used by the media is "invasion", or the more general "attack". An offensive is a conduct of combat operations that seek to achieve only some of the objectives of the strategy being pursued in the theatre as a whole.
Shock tacticsShock tactics, shock tactic, or shock attack is the name of an offensive maneuver which attempts to place the enemy under psychological pressure by a rapid and fully-committed advance with the aim of causing their combatants to retreat. The acceptance of a higher degree of risk to attain a decisive result is intrinsic to shock actions. Shock tactics were usually performed by heavy cavalry, but were sometimes achieved by heavy infantry. The most famous shock tactic is the medieval cavalry charge.
Military engineeringMilitary engineering is loosely defined as the art, science, and practice of designing and building military works and maintaining lines of military transport and military communications. Military engineers are also responsible for logistics behind military tactics. Modern military engineering differs from civil engineering. In the 20th and 21st centuries, military engineering also includes CBRN defense and other engineering disciplines such as mechanical and electrical engineering techniques.
