ABSTRACT
This chapter deals with the collection of the human source intelligence. The thoroughness of Germany's intelligence-gathering capabilities stood that country in good stead in World War I. The intelligence organization conducts its clandestine field operations through the use of "case officers," professionals who are responsible for directing and handling "agents." The United States Diplomatic Mission in each country is responsible for procuring any publicly available documents, maps, or publications which are needed by the intelligence community. The Central Intelligence Agency has the primary responsibility for collecting foreign intelligence by clandestine human sources. The activities of military, naval, and air attaches provide a geographically extensive opportunity for overtly acquiring human intelligence (HUMINT) of military importance. In the United States Government they function as a jointly-manned Defense Attache System. The Federal Bureau of Investigation is a law enforcement organization, but it also has important HUMINT functions since it is largely responsible for conducting counterintelligence activities within the United States.
