MilitaryA military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats.
Military doctrineMilitary doctrine is the expression of how military forces contribute to campaigns, major operations, battles, and engagements. A military doctrine outlines what military means should be used, how forces should be structured, where forces should be deployed, and the modes of cooperation between types of forces. "Joint doctrine" refers to the doctrines shared and aligned by multinational forces or joint service operations.
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.
Military tacticsMilitary tactics encompasses the art of organizing and employing fighting forces on or near the battlefield. They involve the application of four battlefield functions which are closely related – kinetic or firepower, mobility, protection or security, and shock action. Tactics are a separate function from command and control and logistics. In contemporary military science, tactics are the lowest of three levels of warfighting, the higher levels being the strategic and operational levels.
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.
BattleA battle is an occurrence of combat in warfare between opposing military units of any number or size. A war usually consists of multiple battles. In general, a battle is a military engagement that is well defined in duration, area, and force commitment. An engagement with only limited commitment between the forces and without decisive results is sometimes called a skirmish. The word "battle" can also be used infrequently to refer to an entire operational campaign, although this usage greatly diverges from its conventional or customary meaning.
Principles of warPrinciples of war are rules and guidelines that represent truths in the practice of war and military operations. The earliest known principles of war were documented by Sun Tzu, circa 500 BCE, as well as Chanakya in his Arthashastra circa 350BCE. Machiavelli published his "General Rules" in 1521 which were themselves modeled on Vegetius' Regulae bellorum generales (Epit. 3.26.1–33). Henri, Duke of Rohan established his "Guides" for war in 1644. Marquis de Silva presented his "Principles" for war in 1778.
Military personnelMilitary personnel or military service members are members of the state's armed forces. Their roles, pay, and obligations differ according to their military branch (army, navy, marines, coast guard, air force, and space force,), rank (officer, non-commissioned officer, or enlisted recruit), and their military task when deployed on operations and on exercise. Those who serve in a typical large ground or land force are soldiers, this branch is the army. Those who serve in seagoing forces are seamen or sailors, and their branch is a navy or coast guard.
Command and controlCommand and control (abbr. C2) is a "set of organizational and technical attributes and processes ... [that] employs human, physical, and information resources to solve problems and accomplish missions" to achieve the goals of an organization or enterprise, according to a 2015 definition by military scientists Marius Vassiliou, David S. Alberts, and Jonathan R. Agre. The term often refers to a military system.
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.
