Military strategy is a set of ideas implemented by military organizations to pursue desired strategic goals. Derived from the Greek strategos, strategy when it appeared in use during the 18th century, was seen in its narrow sense as the ""art of the general"", 'the art of arrangement' of troops. Military strategy 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 study, Carl von Clausewitz, defined military strategy as ""the employment of battles to gain the end of war."" B. H. Liddell Hart's definition put less emphasis on battles, defining strategy as ""the art of distributing and applying military means to fulfill the ends of policy"". Hence, both gave the pre-eminence to political aims over military goals.Sun Tzu is often considered as the father of Eastern military strategy and has influenced greatly the Chinese, Japanese, Korean and Vietnamese historical and modern war tactics.The Art of War by Sun Tzu grew in popularity and saw practical use in Western society as well. It continues to influence many competitive endeavors in Asia, Europe, and America including culture, politics, and business, as well as modern warfare. The Eastern military strategy differs from the Western by focusing more on asymmetric warfare and deception.Strategy differs from tactics, in that strategy refers to the employment of all of a nation's military capabilities through high level and long term planning, development and procurement to guarantee security or victory. Tactics is the military science employed to secure objectives defined as part of the military strategy; especially the methods whereby men, equipment, aircraft, ships and weapons are employed and directed against an enemy.
