I highly recommend Dr. Adrian Lewis’ book The American Culture of War: the History of U.S. Military Force from World War II to Operation Iraqi Freedom, which focuses on the role that American culture plays in how our forces organize, equip, and fight. It has some keen insights in this regard.

The American Culture of War: The History of U.S. Military Force from World War II to Operation Iraqi Freedom

The American Culture of War is a comprehensive and authoritative survey of American conduct in war from World War II to the present, including both Iraq wars. It traces the evolution of American strategic, operational, and tactical doctrine, including the national command structure, civil-military relations, the role of the media, military technology, the military personnel system, airpower doctrine, the role of Congress, and numerous related aspects of national defence. The American Culture of War will be an indispensable text for upper-division undergradudate courses on the history of war as well as history courses on the Vietnam War and the 1960s.
