About this Unit
The PMO/cID:NIS refers to the Provost Marshal’s Office/Criminal Investigation Division: Naval Investigative Service, a specialized unit within the United States Navy. Established formally in the early 1970s, the NIS evolved from traditional naval policing and investigative roles, focusing on criminal investigations, counterintelligence, and security matters within naval installations. The unit played key roles in major Cold War espionage cases and the enforcement of military law and order aboard ships and shore stations. In 1992, the NIS was reorganized and expanded to become the Naval Criminal Investigative Service (NCIS), taking on broader responsibilities in counterterrorism, cybercrime, and global law enforcement in support of the Navy and Marine Corps.
