The Counter Intelligence Corps was a World War II and early Cold War intelligence agency within the United States Army consisting of highly trained special agents. Its role was taken over by the U.S. Army Intelligence Corps in 1961 and, in 1967, by the United States Army Intelligence Agency. Its functions are now performed by its modern-day descendant organization, United States Army Counterintelligence. The National Counter Intelligence Corps Association (NCICA), a veterans' association, was established in the years immediately following World War II by former military intelligence agents.

The Military Intelligence Corps is the intelligence branch of the United States Army. The primary mission of military intelligence in the U.S. Army is to provide timely, relevant, accurate, and synchronized intelligence and electronic warfare support to tactical, operational and strategic-level commanders. The Army's intelligence components produce intelligence both for Army use and for sharing across the national intelligence community.
