The largest bureaucracy in the US government, in terms of number of personnel, expenditures, and range of authority and operations, is the Department of the Defense (DOD). A unique, comprehensive examination, this handbook provides a reference on the US military administration's historical development, social and legal context, organizational structure, systems and processes, professional development and ethics, and comparisons to other leading military systems in the world. A one-of-a-kind resource, the book includes coverage of the latest DOD transformations brought about during Donald Rumesfeld's tenure as Secretary of Defense.
