In 1985 Thomas C. Thayer's War Without Fronts offered a wealth of data and analysis on U.S. military operations in the Vietnam War and provided a fresh and provocative take on the infamous conflict. When first published, reviewers agreed it was an invaluable text; Vietnam War historians still cite Thayer in modern studies. Long out-of-print, this new edition should facilitate the ongoing conversation about how the American war in Vietnam continues to serve as a comparison for more recent U.S. overseas military campaigns. Thomas Thayer worked as a systems analyst for the Office of the Secretary of Defense during the late 1960s and early 1970s, compiling data to better understand the war and find trends that might help improve U.S. civil and military operations. His work thus offers an insider's view of American military strategy during the Vietnam War and of how military operations affected the Vietnamese people.
