This comparative history of the military helicopter doctrines of the United States, former Soviet Union, the United Kingdom, Germany, and France since World War II focuses on the last twenty years. This unusual analysis of the decision-making process in using helicopters in conventional air-land warfare shows how changes and innovations have developed. An appendix summarizes the technical characteristics of helicopters and a bibliography points to the most significant sources for further research. Photographs bring the helicopters to life; figures clarify the decision-making process; tables add useful data; and a full index makes the history accessible.
