Naval Criminal Investigative Service (NCIS) is a federal law enforcement agency that protects and defends the Department of the Navy against terrorism and foreign intelligence threats, investigates major criminal offenses, enforces the criminal laws of the United States and the UCMJ, assists commands in maintaining good order and discipline, and provides law enforcement and security services to the Navy and Marine Corps on a worldwide basis.
NCIS has the primary jurisdiction within the DON for all alleged, suspected or actual felony criminal offenses, terrorist or intelligence threats and security compromises. This authority includes offenses and incidents on and off U.S. Navy and U.S. Marine Corps installations and vessels worldwide. This jurisdiction is grounded in U.S. federal statutes, executive orders, and DOD and secretary of the Navy policy.
NCIS is in Building 166 on SUBASE and is staffed by 11 civilian special agents. In addition to criminal investigative, counterterrorism and counterintelligence responsibilities, the office offers all commands briefs on counternarcotics, crime prevention, counterintelligence and counterterrorism.
