Multiple Threat Alert Center

United States Department of the Navy's Multiple Threat Alert Center (MTAC) provides indications and warning for a wide range of threats to Navy and Marine Corps personnel and assets around the world.

The MTAC is at the NCIS HQ's located Russell-Knox Building, 27130 Telegraph Road Quantico, VA 22134.

Operated by the Naval Criminal Investigative Service (NCIS), the MTAC utilizes NCIS' worldwide presence and combination of law enforcement, counterintelligence, intelligence and security capabilities to identify all available threat indicators. Analysts, special agents, and military personnel work in the MTAC around the clock to produce indications and warning of possible terrorist activity, foreign intelligence threats and criminal threats that may affect naval operations.

The MTAC is an outgrowth of the Navy Antiterrorist Alert Center (ATAC). The ATAC was established in December 1983 to address the terrorist threat after the bombing of the Marine Corps barracks in Beirut, Lebanon, and the murders of Navy officers in Greece by the Revolutionary Organization 17 November and in El Salvador by the FMLN. As the first 24-hour terrorism watch center in the U.S. Intelligence Community, the ATAC successfully supported the Navy and Marine Corps team for nearly two decades.
