In war, the weapons and technologies employed have direct effects on how battles are waged. When new weapons are introduced, they can dramatically alter the outcomes of warfare--and consequently change the course of history itself. This reference work provides a fascinating overview of the major weapon systems and military technologies that have had a major impact on world history.

Addressing weapons as crude as the club used by primitive man to the high-tech weapons of today such as unmanned drones, Instruments of War: Weapons and Technologies That Have Changed History offers nearly 270 profusely illustrated entries that examine the key roles played by specific weapons and identify their success and failures. The book begins with an introductory essay that frames the subject matter of the work and discusses the history of weapons as a whole. The text is concise and accessible to general readers without extensive backgrounds in military history yet provides the detailed information necessary to convey the complexity of the evolution of warfare through technological change.
