What do Marine Corps security forces predominantly protect?

Marine Corps security forces predominantly protect naval installations. These installations encompass a wide variety of strategic military assets, including naval bases, shoreline facilities, and other key areas that support naval operations. The primary role of security forces at these locations is to ensure the safety, security, and defense of personnel, property, and information against potential threats or unauthorized access.

Naval installations are critical for the operation of naval forces, providing the necessary infrastructure for operations such as maintenance, logistics, and support for the fleet. By focusing on the protection of these installations, Marine Corps security forces contribute directly to the overall effectiveness and readiness of naval operations, ensuring that strategic assets are safeguarded against attacks or sabotage.

In comparison, while security forces do provide protection for military airbases, Navy vessels, and Marine barracks, their main responsibility is linked more closely to the broader operational scope of naval installations, which encompass a range of activities and facilities beyond any single vessel, airbase, or barracks. This reinforces the importance of securing the foundational structures that enable naval readiness and capability.
