The four years between 1941 and 1945 were years in which the nation raised and trained an air armada and committed it to operations on a scale unknown to that time. With Courage: The U.S. Army Air Forces in World War II retells the story of sacrifice, valor, and achievements in air campaigns against tough determined adversaries. It describes the development of a uniquely American doctrine for the application of air power against an opponent’s key industries and centers of national life, a doctrine whose legacy today is the Global Reach-Global Power strategic planning framework of the modern U.S. Air Force. The narrative integrates aspects of strategic intelligence, logistics, technology, and leadership to offer a full yet concise account of the contributions of American air power to victory in that war.-Print Ed.
