Although the DIA is designated a Department of Defense combat support agency, the majority of its 16,500 employees (65%) are civilian and its intelligence operations in support of U.S. national strategic planning extend far beyond the zones of combat. The agency has its own Clandestine Service, which conducts espionage activities around the world, particularly in countries where the military has better access or more specialized military experts than the Central Intelligence Agency. Further, DIA leads the Intelligence Community in collection and production of measurement and signature intelligence.
