A simple example can illustrate the relevancy of the author's work. He traces the rise and fall of Heavy Infantry as the supreme combat arm of the battle field. Infantry in the form of the Phallanx and Legion were displaced by Heavy Cavalry, only to regain dominance as battalions armed with pikes and then bayonet tipped muskets. Armored vehicles, the new Heavy Cavalry once again gained accendancy, but today we see the infantry once more rising to the fore armed with light weight automatic and antitank weapons.

The author helps the layman understand how and why military forces and tactics have changed through 2000 years of history. In so doing he gives us insight into why they look the way they do today, and what forces drive the changes that we see taking place: the push towards lighter and more mobile infantry forces.

Just as technical innovations drove the Phallanx from the battlefield in Roman times and massed regiments from the battlefields in the early 1900's, it is driving change today.
Light air mobile infantry and armor, and special operations forces are being shaped by technology.

This impressive work deserves the widest audience and a place on the bookself of layman and historian alike.

Jones covers it in an excellent and clear writing style. He shows that the development of warfare was both evolutionary and revolutionary. Different weapons systems in the offense or defense give rise to counter systems and so on. Weapons change but successful strategies, operations and tactics still maintain essential "philosophies".

Encyclopedic in its breadth, The Art or War in the Western World is enjoyable reading for those with a serious interest in military history.
