This study investigates the administrative and logistical challenges involved in the rapid mobilization, procurement, and training of United States ground combat forces during World War II. R. R. Palmer, writing under the auspices of the Center of Military History, utilizes official Army records and internal reports to analyze the structural evolution of the training pipeline. The work argues that the transformation of a small peacetime force into a massive, effective combat machine required unprecedented coordination between personnel management and tactical doctrine development.

Historians and military scholars regard this volume as a foundational reference for understanding the institutional history of the U.S. Army during the 1940s. Readers frequently note the academic density of the prose, which prioritizes administrative detail and organizational analysis over anecdotal accounts.
