Staffed by civilian and military personnel, DCS is part of DIA's Directorate of Operations and works in conjunction with the Central Intelligence Agency's Directorate of Operations and the U.S. military's Joint Special Operations Command. DCS consists of about 500 clandestine operatives, which is roughly how many case officers the CIA maintained in the early 2000s prior to its expansion.

The Defense Counterintelligence and Human Intelligence Center (DCHC) is a component of the United States Defense Intelligence Agency.

The Defense Intelligence Agency (DIA) is a military espionage organization of the United States and one of the country's national-level intelligence agencies under the jurisdiction of the U.S. Department of Defense (DoD). Less known than its non-DoD equivalent or its cryptologic counterpart, the DIA and its personnel have at times been portrayed in works of American popular culture.

Document Exploitation (DOCEX) is the set of procedures used by the United States Armed Forces to discover, categorize, and use documents seized in combat operations. In the course of performing its missions in the War on Terrorism, members of the United States Armed Forces discover vast amounts of documents in many formats and languages. When documents are suspected of containing information of potential intelligence value, rapid and accurate interpretation of the information identifies targets, bolsters success in subsequent operations, and enhances tactical and strategic all-source intelligence efforts. The sheer volume of documents acquired in the course of military operations can overwhelm a unit's capability to extract meaningful information in a timely manner.

The Iraq Survey Group (ISG) was a fact-finding mission sent by the multinational force in Iraq after the 2003 invasion of Iraq to find the weapons of mass destruction alleged to be possessed by Iraq that had been the main ostensible reason for the invasion. Its final report, Comprehensive Report of the Special Advisor to the Director of Central Intelligence on Iraq WMD, was submitted to Congress and the president in 2004. It consisted of a 1,400-member international team organized by the Pentagon and Central Intelligence Agency to hunt for the alleged stockpiles of weapons of mass destruction, including chemical and biological agents, and any supporting research programs and infrastructure that could be used to develop WMD. The report acknowledged that only small stockpiles of chemical WMDs were found, the numbers being inadequate to pose a militarily significant threat.

The cards were officially named the "personality identification playing cards". As of 2018, all but 6 of the 52 most wanted have been either killed, or captured.

The Senate Report on Iraqi WMD Intelligence was the report by the United States Senate Select Committee on Intelligence concerning the U.S. intelligence community's assessments of Iraq during the time leading up to the 2003 invasion of Iraq. The report, which was released on July 9, 2004, identified numerous failures in the intelligence-gathering and -analysis process.

Soviet Military Power was a public diplomacy publication of the US Defense Intelligence Agency (DIA), which provided an estimate of the military strategy and capabilities of the Soviet Union during the final years of the Cold War, ostensibly to alert the US public to the significant military capabilities of the Soviet Armed Forces.
