An IC member is a federal government agency, service, bureau, or other organization within the executive branch that plays a role in the business of national intelligence. The Intelligence Community comprises many such organizations.
The Director of National Intelligence (DNI) [link] in the Office of the Director of National Intelligence serves as the head of the Intelligence Community. The DNI also acts as the principal advisor to the President, the National Security Council, and the Homeland Security Council for intelligence matters related to national security; and oversees and directs the implementation of the National Intelligence Program. The President appoints the DNI with the advice and consent of the Senate. The Director is assisted by a Principal Deputy Director of National Intelligence, appointed by the President with the advice and consent of the Senate.
The DNI coordinates intelligence matters related to the Department of Defense (DoD) with the Under Secretary of Defense for Intelligence - the USD(I) [link]. This individual serves as the Principal Staff Assistant and advisor to the Secretary of Defense and the Deputy Secretary of Defense on all intelligence, counterintelligence and security, and other intelligence-related matters. The USD(I) provides oversight and policy guidance for all DoD intelligence activities.
Most intelligence offices or agencies are components of cabinet departments with other roles and missions. The Office of the Director of National Intelligence and the Central Intelligence Agency (CIA) [link] are the only members of the IC that are not part of a cabinet department.
The Central Intelligence Agency (CIA) .s primary mission is to collect, analyze, evaluate, and disseminate foreign intelligence to assist government policymakers in making decisions related to national security. CIA has all-source analytical capabilities that cover the whole world outside US borders. It produces a range of studies that cover virtually any topic of interest to national security policymakers. CIA also collects intelligence with human sources and, on occasion, undertakes covert actions at the direction of the President. (A covert action is an activity or activities of the US Government to influence political, economic, or military conditions abroad, where it is intended that the US role will not be apparent or acknowledged publicly.) CIA.s role is to report only information and not to make policy recommendations.
Three major intelligence agencies in the Department of Defense (DoD) - the National Security Agency (NSA) [link], the National Reconnaissance Office (NRO) [link], and the National Geospatial-Intelligence Agency (NGA) [link] . make up the larger part of the national intelligence budget. NSA is the US.s cryptologic organization, with responsibility for protecting the US Government.s information systems and producing foreign signals intelligence information. Areas of expertise include cryptanalysis, cryptography, mathematics, computer science, and foreign language analysis. The NRO designs, builds, and operates the nation.s signals and imagery reconnaissance satellites. Information collected using NRO satellites is used for a variety of tasks . such as warning of potential foreign military aggression, monitoring weapons of mass destruction programs, enforcing arms control and environmental treaties, and assessing the impact of natural and manmade disasters. The NGA collects and creates information about the Earth for navigation, national security, US military operations, and humanitarian aid efforts. In addition to these three agencies, the Defense Intelligence Agency (DIA) [link] is responsible for defense attaches and for providing DoD with a variety of intelligence products. The Director of DIA is the primary adviser to the Secretary of Defense and the Chairman of the Joint Chiefs of Staff on military intelligence matters. DIA assesses foreign militaries, focusing on weapons of mass destruction, missile systems, terrorism and defense-related medical issues. Although the Intelligence Reform Act provides extensive budgetary and management authorities over these agencies to the Director of National Intelligence, it does not revoke the responsibilities of the Secretary of Defense for these agencies.
The State Department's Bureau of Intelligence and Research (INR) [link] provides interpretative analysis of global developments to the State Department and contributes its unique perspective to the Community.s National Intelligence Estimates and other products. INR's written products cover the full range of geographic and functional areas of expertise. It serves as the focal point within the State Department for all policy issues and activities involving the Intelligence Community and is the Secretary of State.s principal adviser on all intelligence matters.
The Federal Bureau of Investigation (FBI) [link], as an intelligence and law enforcement agency, is responsible for understanding threats to our national security and penetrating national and transnational networks that have a desire and capability to harm the US. The FBI coordinates these efforts with its Intelligence Community and law enforcement partners. FBI focuses on terrorist organizations, foreign intelligence services, WMD proliferators, and criminal enterprises.
The intelligence organizations of the four military services (Air Force [link], Army [link], Navy [link], and Marines [link]) concentrate largely on concerns related to their specific missions. Their analytical products, along with those of DIA, supplement the work of CIA analysts and provide greater depth on key technical issues.
The Homeland Security Act provided the Department of Homeland Security (DHS) [link] responsibilities for fusing law enforcement and intelligence information relating to terrorist threats to the homeland. The Information Analysis and Infrastructure Protection Directorate in DHS participates in the inter-agency counterterrorism efforts and, along with the FBI, has focused on ensuring that state and local law enforcement officials receive information on terrorist threats from national-level intelligence agencies. The Office of Intelligence and Analysis focuses on threats related to border security, CBRN (to include explosives and infectious diseases), critical infrastructure, extremists within the homeland, and travelers entering the homeland.
The Coast Guard [link], now part of DHS, deals with information relating to maritime security and homeland defense. The Coast Guard.s missions include port security, search and rescue, maritime safety, counter-narcotics, and alien migration interdiction.
The Energy Department [link] focuses on assessing worldwide nuclear terrorism threats, nuclear proliferation, and evaluation foreign technology threats.
The Department of the Treasury [link] collects and processes information that may affect US fiscal and monetary policies. Treasury also covers the terrorist financing issue.
The Drug Enforcement Administration (DEA) [link] is the agency responsible for enforcing the controlled substances laws and regulations of the United States. DEA provides drug-related information for the IC acquired during its drug enforcement duties.
