Defense Clandestine Service: The Defense Clandestine Service (DCS) is an arm of the Defense Intelligence Agency (DIA), which conducts clandestine espionage activities around the world to answer national-level defense objectives for senior U.S. policymakers and military leaders.  Staffed by civilian and military personnel, DCS is part of DIA's Directorate of Operations and works in conjunction with the Central Intelligence Agency's Directorate of Operations and the U.S. military's Joint Special Operations Command.  DCS consists of about 500 clandestine operatives, which is roughly how many case officers the CIA maintained in the early 2000s prior to its expansion.

National Security Agency: The National Security Agency (NSA) is a national-level intelligence agency of the United States Department of Defense, under the authority of the Director of National Intelligence.  The NSA is responsible for global monitoring, collection, and processing of information and data for foreign intelligence and counterintelligence purposes, specializing in a discipline known as signals intelligence (SIGINT).

The aircraft are fitted with electronic surveillance equipment and long range cameras capable of taking pictures of targets from high altitudes.  The base was built with the assistance of the Central Intelligence Agency in the early 1960s and was used for aerial surveillance and intelligence gathering of China's strategic forces.  The first aircraft was delivered in the mid 60's and was a World War II vintage C-46 which was outfitted with an oxygen distribution system for operator and flight personnel along with surveillance electronics and recording equipment at the Air America base in Tainan, Taiwan.  The installation was supervised by the design engineer, a Mr. Kent Williamson.  Mr. Williamson, along with other experienced personnel also deployed to Charbatia to train the first operator and maintenance personnel.

National Intelligence Authority (United States): The National Intelligence Authority (NIA) was the United States Government authority responsible for monitoring the Central Intelligence Group (CIG), the successor intelligence agency of the Office of Strategic Services established by President Harry S. Truman's Executive Letter of 22 January 1946 in the aftermath of World War Two.  The National Intelligence Authority and Central Intelligence Group were both replaced respectively by the National Security Council and the Central Intelligence Agency under the National Security Act of 1947 implemented on the 18 September 1947.

As with other U.S. foreign intelligence organizations, the agency's role has occasionally been confused with those of law enforcement agencies.

During the 1971 Bangladesh Independence War, the Bangladesh Forces in the 11 BDF Sectors also developed an intelligence network within its organisation of guerrilla combat teams that provided the sectors with essential local intelligence.  However, the intelligence agency personnel have been and still continues to be recruited and trained from within the particular agency.  Among their varied responsibilities, the members of the Community collect and produce foreign and domestic intelligence, contribute to military planning, and perform espionage.
