Human intelligence (intelligence gathering) in the context of "Intelligence agencies"

The Central Intelligence Agency (CIA /ˌsiː.aɪˈeɪ/) is a civilian foreign intelligence service of the federal government of the United States tasked with advancing national security through collecting and analyzing intelligence from around the world and conducting covert operations. The agency is headquartered in the George Bush Center for Intelligence in Langley, Virginia, and is sometimes metonymously called "Langley". A major member of the United States Intelligence Community (IC), the CIA has reported to the director of national intelligence since 2004, and is focused on providing intelligence for the president and the Cabinet, though it also provides intelligence for a variety of other entities including the US Military and foreign allies.

The CIA is headed by a director and is divided into various directorates, including a Directorate of Analysis and Directorate of Operations. Unlike the Federal Bureau of Investigation (FBI), the CIA has no law enforcement function and focuses on intelligence gathering overseas, with only limited domestic intelligence collection. The CIA is responsible for coordinating all human intelligence (HUMINT) activities in the IC. It has been instrumental in establishing intelligence services in many countries, and has provided support to many foreign organizations. The CIA exerts foreign political influence through its paramilitary operations units, including its Special Activities Center. It has also provided support to several foreign political groups and governments, including planning, coordinating, training and carrying out torture, and technical support. It was involved in many regime changes and carrying out planned assassinations of foreign leaders and terrorist attacks against civilians.

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 on foreign nationals in support of its Five Eyes partners. SIS is one of the British intelligence agencies and the Chief of the Secret Intelligence Service (known as "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" 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 footing for the first time. It provides the legal basis for its operations. Today, SIS is subject to public oversight by the Investigatory Powers Tribunal and the Intelligence and Security Committee of Parliament.

A cover in foreign, military or police human intelligence or counterintelligence is the ostensible identity and role or position in an infiltrated organization assumed by a covert agent during a covert operation.

The All-Russian Extraordinary Commission (Russian: Всероссийская чрезвычайная комиссия, romanized: Vserossiyskaya chrezvychaynaya komissiya, IPA: [fsʲɪrɐˈsʲijskəjə tɕrʲɪzvɨˈtɕæjnəjə kɐˈmʲisʲɪjə]), abbreviated as VChK (Russian: ВЧК, IPA: [vɛ tɕe ˈka]), and commonly known as the Cheka (Russian: ЧК, IPA: [tɕɪˈka]), was the first Soviet secret police organization. It was established on 20 December [O.S. 7 December] 1917 by the Council of People's Commissars of the Russian SFSR, and was led by Felix Dzerzhinsky. By the end of the Russian Civil War in 1922, the Cheka had at least 200,000 personnel.

Ostensibly created to protect the October Revolution from "class enemies" such as the bourgeoisie and members of the clergy, the Cheka soon became a tool of repression wielded against all political opponents of the Bolshevik regime. The organization had responsibility for counterintelligence, oversight of the loyalty of the Red Army, and protection of the country's borders, as well as the collection of human and technical intelligence. At the direction of Vladimir Lenin, the Cheka performed mass arrests, imprisonments, torture, and executions without trial in what came to be known as the "Red Terror". It policed the Gulag system of labor camps, conducted requisitions of food, and put down rebellions by workers and peasants. The Cheka was responsible for executing at least 50,000 to as many as 200,000 people, though estimates vary widely.

The Australian Secret Intelligence Service (ASIS /ˈeɪsɪs/) is the foreign intelligence agency of the Commonwealth of Australia, responsible for gathering, processing, and analysing national security information from around the world, primarily through the use of human intelligence. The service was formed in 1952, however its existence remained secret within much of the government and to the public until 1972. ASIS is a primary entity of the Australian Intelligence Community.

ASIS is part of the Department of Foreign Affairs and Trade (DFAT) portfolio and has its headquarters in Canberra. Its director-general, currently Kerri Hartland, reports to the minister for foreign affairs. The service is comparable to the CIA (US) and MI6 (UK).

Special reconnaissance (SR) is conducted by small units, such as a recon team, made up of highly trained military personnel, usually from special forces units and/or military intelligence organizations. Special reconnaissance teams operate behind enemy lines, avoiding direct combat and detection by the enemy. As a role, SR is distinct from commando operations, but both are often carried out by the same units. The SR role frequently includes covert direction of airstrikes and indirect fire, in areas deep behind enemy lines, placement of remotely monitored sensors, and preparations for other special forces. Like other special forces, SR units may also carry out direct action and unconventional warfare, including guerrilla operations.

In intelligence terms, SR is a human intelligence (HUMINT) collection discipline. Its operational control is likely to be inside a compartmented cell of the HUMINT, or possibly the operations, staff functions. Since such personnel are trained for intelligence collection as well as other missions, they will usually maintain clandestine communications to the HUMINT organization and will be systematically prepared for debriefing. They operate significantly farther forward than even the most forward friendly scouting and surveillance units.

Strategic intelligence (STRATINT) pertains to the collection, processing, analysis, and dissemination of intelligence that is required for forming policy and military plans at the national and international level. Much of the information needed for strategic reflections comes from Open Source Intelligence. Other sources include traditional HUMINT (especially in recent years), Signals intelligence including ELINT, MASINT which overlaps with SIGINT/ELINT to some degree, and 'National technical means of verification' (e.g. spysats). The father of intelligence analysis and of the strategic intelligence concept was Sherman Kent, in his seminal work Strategic Intelligence for American World Policy, first published in 1949. For Kent, strategic intelligence is ”the knowledge upon which our nation's foreign relations, in war and peace, must rest".

Strategic intelligence pertains to the following system of abilities that, according to Michael Maccoby, characterize some of the most successful leaders in business, government and military.:
