Military art (French: L'Art de la Guerre) (lit. art of war) is a field of theoretical research and training methodology in military science used in the conduct of military operations on land, in the maritime or air environments. Military art includes the study and application of the principles of warfare and laws of war that apply equally to the closely interrelated military strategy, operational art and tactics. Exercise of military art is highly dependent on the economics and logistics supporting the armed forces, their military technology and equipment, and reflects the social influences on the military organisation exercising military art. Often misunderstood due to its 19th-century perception as generally "including the entire subject of war", it is primarily, as the term implies, the expression of creative thinking on the part of the decision-makers in employing their forces, with the map of the area of operations as a veritable canvas, and the movement of forces commonly marked on the map with arrows, as brush strokes. Less imaginatively it was defined in France during the 19th century as
