Quadrennial defense review

DOD is required by law to conduct a comprehensive examination of the national defense strategy, force structure, force modernization plans, infrastructure, budget plan, and other elements of the defense program and policies of the United States, every 4 years, with a view toward determining and expressing the nation's defense strategy and establishing a defense program for the next 20 years. This report assesses the degree to which DOD addressed each of these items in its 2010 report on the QDR and the supplemental information provided to the defense committees.
