NCIS' Mission: Reduce Crime

NCIS is the Department of the Navy's primary law enforcement arm. NCIS investigates all major criminal offenses (felonies)—that is, those crimes punishable under the Code of Military Justice by confinement of more than one year—within the Department of the Navy.

Crime poses a threat to every segment of today's society, including the Navy and Marine Corps. These criminal threats can include homicide, arson, domestic violence, drug trafficking, as well as white-collar offenses such as procurement fraud or embezzlement.
