DoD reported resources of more than $1.5 billion for fiscal year 2010 to support its counter-narcotics activities. This report addresses the extent to which: (1) DoD's counter-narcotics performance measurement system enables DoD to track progress; and (2) DoD uses performance information from its counter-narcotics performance measurement system to manage its activities. The report analyzed relevant DoD performance and budget documents, and discussed these efforts with officials from DoD and the Office of National Drug Control Policy. Includes recommendations.
