Jan Fischer, American Soldier In His Military Life

Later this became known as Military Science, and later still would adopt the scientific method approach to the conduct of military operations under the influence of the Industrial Revolution thinking. In his seminal book On War the Prussian Major-General and leading expert on modern military strategy Carl von Clausewitz defined military strategy as "the employment of battles to gain the end of war." According to Clausewitz
strategy forms the plan of the War, and to this end it links together the series of acts which are to lead to the final decision, that is to say, it makes the plans for the separate campaigns and regulates the combats to be fought in each.
Hence, Clausewitz placed political aims above military goals, ensuring civilian control of the military. Military strategy was one of a triumvirate of "arts" or "sciences" that governed the conduct of warfare, the others being: military tactics, the execution of plans and manœuvering of forces in battle, and maintenance of an army.
The meaning of military tactics has changed over time from the deployment and manoeuvreing of entire land armies on the fields of ancient battles, and galley fleets, to modern use of small unit ambushes, encirclements, bomb and bombardment attacks, frontal assaults, air assaults, hit-and-run tactics used mainly by guerrilla forces and, in some cases, suicide attacks on land and at sea. Evolution of aerial warfare introduced its own air combat tactics. Often, military deception, in the form of military camouflage or misdirection using decoys, is used to confuse the enemy as a tactic.
