United States Intelligence Community in the context of "Directorate of Operations (CIA)"

The United States Department of Defense (DoD), also referred to as the Department of War (DoW), is an executive department of the U.S. federal government charged with coordinating and supervising the U.S. Armed Forces—the Army, Navy, Marines, Air Force, Space Force, and, for some purposes, the Coast Guard—and related functions and agencies. Headquartered at the Pentagon in Arlington County, Virginia, just outside Washington, D.C., the stated mission of the Department of Defense is "to provide the military forces needed to deter war and ensure our nation's security".

The Department of Defense is headed by the secretary of defense, a cabinet-level head who reports directly to the president of the United States. The president is commander-in-chief of the U.S. armed forces. Beneath the Department of Defense are three subordinate military departments: the Department of the Army, the Department of the Navy, and the Department of the Air Force. In addition, four national intelligence services are subordinate to the Department of Defense: the Defense Intelligence Agency, National Security Agency (NSA), National Geospatial-Intelligence Agency, and National Reconnaissance Office.

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 Defense Intelligence Agency (DIA) is an intelligence agency and combat support agency of the United States Department of Defense (DoD) specializing in military intelligence.

A component of the Department of Defense and the Intelligence Community (IC), DIA informs national civilian and defense policymakers about the military intentions and capabilities of foreign governments and non-state actors. It also provides intelligence assistance, integration and coordination across uniformed military service intelligence components, which remain structurally separate from DIA. The agency's role encompasses the collection and analysis of military-related foreign political, economic, industrial, geographic, and medical and health intelligence. DIA produces approximately one-quarter of all intelligence content that goes into the President's Daily Brief.

The National Geospatial-Intelligence Agency (NGA) is a combat support agency within the United States Department of Defense whose primary mission is collecting, analyzing, and distributing geospatial intelligence (GEOINT) to support national security. Founded in 1996 as the National Imagery and Mapping Agency (NIMA), it changed names in 2003. It is a member of the United States Intelligence Community.

NGA headquarters, also known as NGA Campus East or NCE, is located at Fort Belvoir North Area in Springfield, Virginia. At 2,300,000 square feet (210,000 m), it is the third-largest government building in the Washington metropolitan area after the Pentagon and the Ronald Reagan Building. The agency also operates NGA Campus West, or NCW, in St. Louis, Missouri, and support and liaison offices worldwide.

The National Reconnaissance Office (NRO) is a member of the United States Intelligence Community and an agency of the United States Department of Defense which designs, builds, launches, and operates the reconnaissance satellites of the U.S. federal government. It provides satellite intelligence to several government agencies, particularly signals intelligence (SIGINT) to the National Security Agency (NSA), imagery intelligence (IMINT) to the National Geospatial-Intelligence Agency (NGA), and measurement and signature intelligence (MASINT) to the Defense Intelligence Agency (DIA). The NRO announced in 2023 that it plans within the following decade to quadruple the number of satellites it operates and increase the number of signals and images it delivers by a factor of ten.

NRO is considered, along with the Central Intelligence Agency (CIA), NSA, DIA, and NGA, to be one of the "big five" U.S. intelligence agencies. The NRO is headquartered in Chantilly, Virginia, 2 miles (3.2 km) south of Washington Dulles International Airport.

The director of national intelligence (DNI) is a cabinet-level United States government intelligence and security official. The position is required by the Intelligence Reform and Terrorism Prevention Act of 2004 to serve as executive head of the United States Intelligence Community (IC) and to direct and oversee the National Intelligence Program (NIP). All 18 IC agencies, including the Central Intelligence Agency (CIA), the Defense Intelligence Agency (DIA) and the National Security Agency (NSA), report directly to the DNI. Other federal agencies with intelligence capabilities also report to the DNI, including the Federal Bureau of Investigation (FBI).

The DNI also serves as the principal advisor to the president of the United States, the National Security Council, and the Homeland Security Council on all intelligence matters. The DNI, supported by the Office of the Director of National Intelligence (ODNI), produces the President's Daily Brief, a highly classified document including intelligence from all IC agencies, shared each morning with the president of the United States. The DNI, who is appointed by the president of the United States and is subject to confirmation by the United States Senate, serves at the pleasure of the president.

The director of the Central Intelligence Agency (D/CIA) is a statutory office (50 U.S.C. § 3036) that functions as the head of the Central Intelligence Agency, which in turn is a part of the United States Intelligence Community.

The director reports to the director of national intelligence (DNI) and is assisted by the deputy director of the Central Intelligence Agency (DD/CIA). The director is a civilian or a general or flag officer of the United States Armed Forces nominated by the president of the United States, with the recommendation from the DNI, and must be confirmed by a majority vote of the United States Senate.

The Federal Bureau of Investigation (FBI) is the primary federal law enforcement agency in the United States and also the American domestic intelligence and security service. An agency of the United States Department of Justice, the FBI is a member of the U.S. Intelligence Community and reports to both the attorney general and the director of national intelligence. A leading American counterterrorism, counterintelligence, and criminal investigative organization, the FBI has jurisdiction over violations of more than 200 categories of federal crimes. The FBI maintains a list of its top 10 most wanted fugitives.

Although many of the FBI's functions are unique, its activities in support of national security are comparable to those of the British MI5 and NCA and the Russian FSB. Unlike the Central Intelligence Agency (CIA), which has no law enforcement authority and is focused on intelligence collection abroad, the FBI is primarily a domestic agency, maintaining 56 field offices in major cities throughout the United States, and more than 400 resident agencies in smaller cities and areas across the nation. At an FBI field office, a senior-level FBI officer concurrently serves as the representative of the director of national intelligence.

The National Center for Medical Intelligence (NCMI), formerly known as the Armed Forces Medical Intelligence Center, is a component of the United States Defense Intelligence Agency (DIA) responsible for the production of medical intelligence and all-source intelligence on foreign health threats and other medical issues to protect U.S. interests worldwide. Headquartered at Fort Detrick, Maryland, the center provides finished intelligence products to the Department of Defense, U.S. Intelligence Community, Five Eyes, NATO, allies and partners, as well as international health organizations and NGO's.

As of April 2020, NCMI is led by director Colonel R. Shane Day and deputy director Christopher M. Strub.

The President's Daily Brief, sometimes referred to as the President's Daily Briefing or the President's Daily Bulletin, is a top-secret document produced and given each morning to the president of the United States; it is also distributed to a small number of top-level US officials who are approved by the president. It includes highly classified intelligence analysis, information about covert operations, and reports from the most sensitive US sources or those shared by allied intelligence agencies. At the discretion of the president, the PDB may also be provided to the president-elect of the United States, between election day and inauguration, and to former presidents on request.

The PDB is produced by the director of national intelligence, and involves fusing intelligence from the Central Intelligence Agency, the Defense Intelligence Agency, the National Security Agency (NSA), the Federal Bureau of Investigation (FBI), the Defense Department, Homeland Security and other members of the U.S. Intelligence Community.

In the United States, geospatial intelligence (GEOINT) is intelligence about the human activity on Earth derived from the exploitation and analysis of imagery, signals, or signatures with geospatial information. GEOINT describes, assesses, and visually depicts physical features and geographically referenced activities on the Earth. GEOINT, as defined in US Code, consists of imagery, imagery intelligence (IMINT) and geospatial information.

Today, GEOINT knowledge and tradecraft are not confined to the U.S. government, or even the world's leading military powers. Additionally, countries such as India are holding GEOINT-specific conferences. While other countries may define geospatial intelligence somewhat differently than does the U.S., the use of GEOINT data and services is the same.

The United States Senate Select Committee on Intelligence (sometimes referred to as the Intelligence Committee or SSCI) is dedicated to overseeing the United States Intelligence Community—the agencies and bureaus of the federal government of the United States that provide information and analysis for leaders of the executive and legislative branches. The Committee was established in 1976 by the 94th Congress.

The Committee is "select" in that membership is temporary and rotated among members of the chamber. The committee comprises 15 members. Eight of those seats are reserved for one majority and one minority member of each of the following committees: Appropriations, Armed Services, Foreign Relations, and Judiciary. Of the remaining seven, four are members of the majority, and three are members of the minority. In addition, the Majority Leader and Minority Leader are non-voting ex officio members of the committee. Also, the Chair and Ranking Member of the Committee on Armed Services (if not already a member of the select Committee) are ex officio members.

The Federal Bureau of Investigation (FBI) is the domestic intelligence and security service of the United States and its principal federal law enforcement agency. An agency of the United States Department of Justice, the FBI is a member of the U.S. Intelligence Community and reports to both the attorney general and the director of national intelligence. A leading American counterterrorism, counterintelligence, and criminal investigative organization, the FBI has jurisdiction over violations of more than 200 categories of federal crimes. The FBI maintains a list of its top 10 most wanted fugitives.

Although many of the FBI's functions are unique, its activities in support of national security are comparable to those of the British MI5 and NCA and the Russian FSB. Unlike the Central Intelligence Agency (CIA), which has no law enforcement authority and is focused on intelligence collection abroad, the FBI is primarily a domestic agency, maintaining 56 field offices in major cities throughout the United States, and more than 400 resident agencies in smaller cities and areas across the nation. At an FBI field office, a senior-level FBI officer concurrently serves as the representative of the director of national intelligence.

The director of central intelligence (DCI) was the head of the American Central Intelligence Agency (CIA) from 1946 to 2004, acting as the principal intelligence advisor to the president of the United States and the United States National Security Council, as well as the coordinator of intelligence activities among and between the various US intelligence agencies (collectively known as the Intelligence Community from 1981 onwards).

The office existed from January 1946 to December 17, 2004. After the Intelligence Reform and Terrorism Prevention Act it was replaced by the director of national intelligence (DNI) as head of the Intelligence Community and the director of the Central Intelligence Agency (D/CIA) as head of the CIA.
