Human Intelligence (HUMINT) is a type of intelligence gathering that involves the collection and analysis of information from human sources. This can include information gathered through traditional espionage, interviews, interrogations, and the exploitation of documents and media. HUMINT is widely considered to be one of the most important forms of intelligence and can provide valuable insights and perspectives that are not available from other sources.
