Naval Security Forces

The Naval Security Forces (NSF) is a specialized unit within the United States Navy responsible for the protection and security of naval installations, personnel, and assets worldwide. Originating from the traditional roles of Navy Master-at-Arms, the NSF was formally established to address evolving security threats, including terrorism, espionage, and sabotage. Throughout its history, the NSF has played a crucial role in force protection, anti-terrorism operations, and law enforcement activities both onshore and afloat. Their presence is vital for safeguarding key naval infrastructure and ensuring mission readiness in support of U.S. naval operations globally.
