In War, do mass and material mater most? Will States with the largest, best equipped, information technology-rich militaries invariable win? The prevailing answer today among both scholars and policy makers is yes. But this is to overlook force employment, or the doctrine and tactics by which material is actually used. In a landmark reconeption of battle and war, this book provides a systematic account of how force employment interacts with material to produce real combat outcomes. Stephen Biddle argues that force employment is central to modern war, becoming increasingly important sice 1900 as the key to surviving ever more letha weaponry. Technological change produces opposite effects depending on how forces are employed; to focus only on material is thus to risk major error-with serious consequences for both policy and scholarship.
