U.S. Army Criminal Investigation Command (USACIAC) is the Army's primary criminal investigative organization. It is responsible for conducting criminal investigations in which the Army is, or may be, a party of interest.
Headquartered at Fort Belvoir, Virginia and operating throughout the world, CID Special Agents conduct criminal investigations that range from death to fraud, on and off military reservations and when appropriate, with local, state and other federal investigative agencies.
CID supports the Army through the deployment, in peace and war, of highly trained Special Agents and support personnel, the operation of a certified forensic laboratory, a protective services unit, computer crimes specialists, polygraph services, criminal intelligence collection and analysis and a variety of other services normally associated with law enforcement activities.
Its mission is the same in both the installation and battlefield environments, however, additional requirements are taken on during battlefield support.
