Department of the Army Criminal Investigation Division

The Department of the Army Criminal Investigation Division (CID), previously known as the United States Army Criminal Investigation Command (USACIDC) is the primary federal law enforcement agency of the United States Department of the Army. Its primary function is to investigate felony crimes and serious violations of military law & the United States Code within the US Army. The division is a separate military investigative force with investigative autonomy; CID special agents, both military and civilian, report through the CID chain of command to the USACID Director, who reports directly to the Under Secretary of the Army and the Secretary of the Army. Unlike their counterparts at OSI and NCIS, Army CID does not have primary counterintelligence responsibilities.
