From fiscal years 1994 through 2009, the Department of Defense (DOD) separated over 13,000 active military servicemembers under its homosexual conduct policy. These separations represent about 0.37 percent of the 3.6 million members separated for all reasons, including expiration of terms of service and retirement. In 2005, GAO reported on the number of separated servicemembers under DOD's homosexual conduct policy who held critical skills and the costs associated with administering the policy from fiscal years 1994 through 2003. GAO was asked to examine data from fiscal years 2004 through 2009 to determine (1) the extent to which the policy has resulted in the separation of servicemembers with skills in critical occupations and important foreign languages and (2) the services' costs for certain activities associated with administering the policy. GAO obtained and analyzed DOD personnel and cost data; examined DOD regulations and policy documents; and conducted interviews with officials from the Office of the Under Secretary of Defense for Personnel and Readiness, the Defense Manpower Data Center, and each of the military services. GAO provided a draft of this report to DOD for review and comment. DOD did not have any comments on the report.
