Intelligence-gathering
This is a list of intelligence gathering disciplines. HUMINT Human intelligence (HUMINT) are gathered from a person in the location in question. Sources can include the following: * Advisors or foreign internal defense (FID) personnel working with host nation (HN) forces or populations * Diplomatic reporting by accredited diplomats (e.g. military attachés) * Espionage clandestine reporting, access agents, couriers, cutouts * Military attachés * Non-governmental organizations (NGOs) * Prisoners of war Prisoners of war (POWs) or detainees * Refugees * Routine patrolling (military police, patrols, etc.) * Special reconnaissance * Traveler debriefing (e.g. CIA Domestic Contact Service) MI6 is often thought to use human intelligence to operate in different countries or Britain itself to protect the country from global affairs. However, this is usually confused with their brother agency MI5, which focuses on the security of Britain. GEOINT Geospatial intelligence (GEO ...

Communications Intelligence
Signals intelligence (SIGINT) is list of intelligence gathering disciplines, intelligence-gathering by interception of ''Signal, signals'', whether communications between people (communications intelligence—abbreviated to COMINT) or from electronic signals not directly used in communication (electronic intelligence—abbreviated to ELINT). Signals intelligence is a subset of intelligence collection management. As classified information, classified and sensitive information is usually encryption, encrypted, signals intelligence in turn involves the use of cryptanalysis to decipher the messages. Traffic analysis—the study of who is signaling whom and in what quantity—is also used to integrate information again. History Origins Electronic interceptions appeared as early as 1900, during the Boer War of 1899–1902. The British Royal Navy had installed wireless sets produced by Marconi on board their ships in the late 1890s, and the British Army used some limited wireless si ...

Espionage
Espionage, spying, or intelligence gathering is the act of obtaining secret or confidential information ( intelligence) from non-disclosed sources or divulging of the same without the permission of the holder of the information for a tangible benefit. A person who commits espionage is called an ''espionage agent'' or ''spy''. Any individual or spy ring (a cooperating group of spies), in the service of a government, company, criminal organization, or independent operation, can commit espionage. The practice is clandestine, as it is by definition unwelcome. In some circumstances, it may be a legal tool of law enforcement and in others, it may be illegal and punishable by law. Espionage is often part of an institutional effort by a government or commercial concern. However, the term tends to be associated with state spying on potential or actual enemies for military purposes. Spying involving corporations is known as industrial espionage. One of the most effective ways ...

Telemetry
Telemetry is the in situ collection of measurements or other data at remote points and their automatic transmission to receiving equipment (telecommunication) for monitoring. The word is derived from the Greek roots ''tele'', "remote", and ''metron'', "measure". Systems that need external instructions and data to operate require the counterpart of telemetry, telecommand. Although the term commonly refers to wireless data transfer mechanisms (e.g., using radio, ultrasonic, or infrared systems), it also encompasses data transferred over other media such as a telephone or computer network, optical link or other wired communications like power line carriers. Many modern telemetry systems take advantage of the low cost and ubiquity of GSM networks by using SMS to receive and transmit telemetry data. A ''telemeter'' is a physical device used in telemetry. It consists of a sensor, a transmission path, and a display, recording, or control device. Electronic devices are widely ...

Military Attaché
A military attaché is a military expert who is attached to a diplomatic mission, often an embassy. This type of attaché post is normally filled by a high-ranking military officer, who retains a commission while serving with an embassy. Opportunities sometimes arise for service in the field with military forces of another sovereign state. The attache has the privileges of a foreign diplomat. History An early example, General Edward Stopford Claremont, served as the first British military attaché (at first described as "military commissioner") based in Paris for 25 years from 1856 to 1881. Though based in the embassy, he was attached to the French army command during the Crimean War of 1853-1856 and later campaigns. The functions of a military attaché are illustrated by actions of U.S. military attachés in Japan around the time of the Russo-Japanese war of 1904–1905. A series of military officers had been assigned to the American diplomatic mission in Tokyo since 1901, whe ...

Secret Intelligence Service
The Secret Intelligence Service (SIS), commonly known as MI6 ( Military Intelligence, Section 6), is the foreign intelligence service of the United Kingdom, tasked mainly with the covert overseas collection and analysis of human intelligence in support of the UK's national security. SIS is one of the British intelligence agencies and the Chief of the Secret Intelligence Service ("C") is directly accountable to the Foreign Secretary. Formed in 1909 as the foreign section of the Secret Service Bureau, the section grew greatly during the First World War officially adopting its current name around 1920. The name "MI6" (meaning Military Intelligence, Section 6) originated as a convenient label during the Second World War, when SIS was known by many names. It is still commonly used today. The existence of SIS was not officially acknowledged until 1994. That year the Intelligence Services Act 1994 (ISA) was introduced to Parliament, to place the organisation on a statutory foo ...

Foreign Internal Defense
Foreign internal defense (FID) is a term used by the military in several countries, including the United States, France, and the United Kingdom, to describe an integrated, and possibly multi-country, approach to combating actual or threatened insurgency in a foreign state. This foreign state is known as the Host Nation (HN) under the US (and generally accepted NATO) doctrine. The term counter-insurgency is more commonly used worldwide than FID. FID involves military deployment of counter-insurgency specialists. According to the US doctrinal manual, ''Joint Publication 3-22: Foreign Internal Defense (FID)'', these specialists generally do not do the actual fighting.Joint Publication 3-22: Foreign Internal Defense (FID)', US Department of Defense, 12 July 2010 Doctrine calls for a close working relationship between the Host Nation government and security specialists which could include diplomatic, information, intelligence, military, economic, and other specialties. A successfu ...

Materials MASINT
Materials MASINT is one of the six major disciplines generally accepted to make up the field of Measurement and Signature Intelligence (MASINT), with due regard that the MASINT subdisciplines may overlap, and MASINT, in turn, is complementary to more traditional intelligence collection and analysis disciplines such as SIGINT and IMINT. MASINT encompasses intelligence gathering activities that bring together disparate elements that do not fit within the definitions of Signals Intelligence (SIGINT), Imagery Intelligence (IMINT), or Human Intelligence (HUMINT). According to the United States Department of Defense, MASINT is technically derived intelligence (excluding traditional imagery IMINT and signals intelligence SIGINT) that – when collected, processed, and analyzed by dedicated MASINT systems – results in intelligence that detects, tracks, identifies, or describes the signatures (distinctive characteristics) of fixed or dynamic target sources. MASINT was recognized as a fo ...

Telemetry Intelligence
Telemetry intelligence (TELINT) is a subdiscipline of FISINT which is concerned with missiles and other remotely monitored devices sending back continuous streams of data about their location, speed, engine status and other metrics. This data can provide information on the performance of the missile and especially its throw-weight, i.e. the potential size of its warheads. Strategic significance of TELINT TELINT is one of the "national means of technical verification" mentioned, but not detailed, in the Strategic Arms Limitation Treaty (SALT) between the US and USSR. The SALT I treaty language "the agreements include provisions that are important steps to strengthen assurance against violations: both sides undertake not to interfere with national technical means of verification. In addition, both countries agree not to use deliberate concealment measures to impede verification." refers to, in part, a technical agreement not to encrypt strategic test telemetry and thus impede verific ...

Foreign Instrumentation Signals Intelligence
Foreign instrumentation signals intelligence, FISINT (''F''oreign ''I''nstrumentation ''S''ignature ''INT''elligence) is intelligence from the interception of foreign electromagnetic emissions associated with the testing and operational deployment of foreign aerospace, surface, and subsurface systems. Since it deals with signals that have communicational content, it is a subset of Communications Intelligence (COMINT), which, in turn, is a subset of SIGINT. Unlike general COMINT signals, the content of FISINT signals is not in regular human language, but rather in machine to machine (instrumentation) language or in a combination of regular human language and instrumentation language. FISINT is also considered as a subset of MASINT (measurement and signature intelligence). Typical examples of such communication include: *Telemetry data (TELINT). Missiles, satellites and other remotely monitored devices often transmit streams of data concerning their location, speed, engine status and ...

Acoustical Intelligence
Acoustical intelligence (ACOUSTINT, sometimes ACINT) is an intelligence gathering discipline that collects and processes acoustic phenomena. It is a subdiscipline of MASINT ( Measurement and Signature Intelligence). This uses broadband and narrowband analysis of acquired acoustic signatures from surface ships and submarines, although it can also be used for low-flying aircraft such as helicopters. Broadband analysis concerns the overall noise created by a platform, whereas narrowband analysis examines the spectra of the received energy at a more precise level. Broadband analysis is useful for identifying any vessel at a long range, whereas narrowband analysis is generally more useful for identifying the category, type and ideally the individual vessel name. The category might be for example differentiating between a commercial vessel and a warship; the type might be narrowing this down to an individual class and hence identifying nationality, and the individual name might ident ...
