Query: Foundation of Military Science

Sun Tzu's "Art of War" is truly one of the great military classics of all time. Although it is over 2000 years old, virtually all modern military academies consider it to be a cornerstone of the Military Science curriculum. Sun Tzu's attitude toward war, as an expensive and unfortunate necessity that needs to be dealt with in a rational manner, is presented from the outset and it establishes the basis for his lessons.His steps in logical progression through the essential elements: motivation, logistics, strategy, tactics and intelligence are, of course, dated. The most important element is the value of applying intelligent, rational consideration to develop the most effective course of action given the circumstances at hand.The number of absolutely essential books on warfare can probably be counted on one hand. This one is number one.
