This volume examines the organizational structure, strategic decision-making processes, and operational functions of the War Department’s Operations Division during the Second World War. Ray S. Cline, serving as a historian for the Department of the Army, utilizes internal records and administrative documentation to reconstruct the command architecture that directed American military efforts. The text argues that the Operations Division served as the critical nexus between political leadership and field command, effectively managing the global logistics and tactical coordination required for a multi-theater conflict.

Historians and military researchers recognize this work as a foundational administrative record of the United States military command structure during the 1940s. Readers frequently note the high density of technical detail and the formal, bureaucratic tone characteristic of official government historical publications.
