It is the successor of the Office of Strategic Services (OSS) formed during World War II to coordinate espionage activities against the Axis Powers for the branches of the United States Armed Forces.
The primary function of the CIA is to collect information about foreign governments, corporations, and individuals, and to advise public policymakers. The agency conducts covert operations and paramilitary actions, and exerts foreign political influence through its Special Activities Division.
Sometimes, in government and military circles the CIA is indirectly referred to as Other Government Agencies (OGA), particularly when its operations in a particular area are an open secret. Other terms include The Company, Langley and The Agency.
The National Security Agency/Central Security Service (NSA/CSS) is a cryptologic intelligence agency of the United States Department of Defense responsible for the collection and analysis of foreign communications and foreign signals intelligence, as well as protecting U.S. government communications and information systems, which involves cryptanalysis and cryptography.
The NSA is directed by at least a lieutenant general or vice admiral. NSA is a key component of the U.S. Intelligence Community, which is headed by the Director of National Intelligence. The Central Security Service is a co-located agency created to coordinate intelligence activities and co-operation between NSA and other U.S. military cryptanalysis agencies. The Director of the NSA is also the Commander of the Joint Functional Component Command – Network Warfare. NSA's work is limited to communications intelligence; it does not perform field or human intelligence activities.
The Central Security Service (CSS) is an agency of the United States Department of Defense, established in 1972 by a Presidential Directive to promote full partnership between the National Security Agency (NSA) and the Service Cryptologic Elements (SCE) of the United States Armed Forces.
The blue background of the CSS emblem represents "fidelity" and "steadfastness", with the symbols for the cryptologic service elements provided shown clockwise from top right as follows: Army Intelligence and Security Command, United States Marine Corps, Naval Security Group, United States Coast Guard and Air Force Intelligence, Surveillance and Reconnaissance Agency with the symbol of the National Security Agency in the center.
NSA/CSS was initially conceived as a separate "fourth service" beside the three U.S. armed services. The latter three resisted this idea, and therefore the CSS was founded as an inter-service organization. The day-to-day work of the CSS is to capture enemy signals (radar, telemetry, radio/satellite communications) using the means of the involved service. For example, the Navy has special submarines for tapping undersea cables; the Air Force operates aircraft with sophisticated antennas and processing gear to listen to enemy radar and radio; and on the ground, the Army operates similar eavesdropping equipment.
a component command of the United States Special Operations Command (USSOCOM) and is charged to study special operations requirements and techniques to ensure interoperability and equipment standardization, plan and conduct special operations exercises and training, and develop Joint Special Operations Tactics. It was established in 1980 on recommendation of Col. Charlie Beckwith, in the aftermath of the failure of Operation Eagle Claw. It is located at Pope Army Air Field and Fort Bragg in North Carolina, USA. The Joint Special Operations Command (JSOC) also commands and controls the Special Mission Units (SMU) of United States Special Operations Command (USSOCOM). These units perform highly classified activities. So far, only three SMUs have been publicly disclosed: The Army's 1st Special Forces Operational Detachment - Delta, the Navy's Naval Special Warfare Development Group, and the Air Force's 24th Special Tactics Squadron. The Intelligence Support Activity is also under JSOC.
DEVGRU's full mission is classified but is thought to include preemptive, pro-active counterterrorist operations, counter-proliferation (efforts to prevent the spread of both conventional weapons and weapons of mass destruction), as well as assassination or recovery of high-value targets (HVTs) from unfriendly nations. DEVGRU is one of only a handful of U.S. special mission units authorized to use preemptive actions against terrorists and their facilities.
The 160th Special Operations Aviation Regiment (Airborne) is a special operations unit of the United States Army that provides helicopter aviation support for general purpose forces and Special Operations Forces. Its missions have included attack, assault, and reconnaissance, and are usually conducted at night, at high speeds, low altitudes, and on short notice. The 160th SOAR is headquartered at Fort Campbell, Kentucky. The 160th SOAR (A) are also known as the Night Stalkers and their motto is Night Stalkers Don't Quit.
The National Geospatial-Intelligence Agency (NGA) is an agency of the United States Government with the primary mission of collection, analysis, and distribution of geospatial intelligence (GEOINT) in support of national security. NGA was formerly known as the National Imagery and Mapping Agency (NIMA) and is part of the Department of Defense (DoD). In addition, NGA is a key component of the United States Intelligence Community.
NGA's headquarters are located in Bethesda, Maryland and operates major facilities in the Northern Virginia, Washington, D.C., and St. Louis, Missouri areas as well as support and liaison offices worldwide. In 2011 NGA expects to consolidate many of its regional activities as part of the BRAC in a new campus near Ft. Belvoir in Fairfax County, Virginia, which will become the third-largest government building in the Washington Metropolitan Area. Its budget and number of employees are classified.
The NGA was credited by White House and military officials with providing critical information in support of Operation Geronimo on May 2, 2011.
