This book is one of a number in the present series that describe what happened to the U.S. Army in World War II as the result of two prevailing circumstances. One was that the War Department had a vital interest and a leading role in maintaining the production of supplies needed to win the war. The other was that, once organized for war, the War Department and the Army comprised an administrative machine incomparably more efficient for getting things done than any other at the disposal of the President. In both connections Army officers found themselves drawn into the realm of industrial management-one surely remote from the field of battle. A companion volume, The Army and Economic Mobilization, shows how extensively and deeply the War Department became involved in business relationships. The authors of the present volume examine and illustrate the ways in which the Army and its officers dealt with the problems into which they were drawn in dealing with organized labor. Since World War II the Army has become even more deeply involved in relations, present and potential, with industry and industrial management. No officer can therefore afford to overlook the instructive experience that this book recounts.
