Human intelligence (intelligence gathering)

NATO defines HUMINT as "a category of intelligence derived from information collected and provided by human sources." A typical HUMINT activity consists of interrogations and conversations with persons having access to information. As the name suggests, human intelligence is mostly collected by people and is commonly provided via espionage or some other form of covert surveillance. However, there are also overt methods of collection, such as via interrogation of subjects or simply through interviews. The manner in which HUMINT operations are conducted is dictated by both official protocol and the nature of the source of the information. Within the context of the United States Armed Forces' military intelligence, HUMINT activity may involve clandestine activities; however, these operations are more closely associated with CIA projects. Both counterintelligence and HUMINT include clandestine human intelligence and its associated operational techniques. == Sources ==
