Who is responsible for areas of the installation not specifically covered by pier watch standers?

The patrol supervisor is responsible for areas of the installation that are not specifically covered by pier watch standers. This role includes overseeing the patrols conducted throughout the installation and ensuring that all areas are monitored adequately. The patrol supervisor coordinates the movements and activities of the patrols to enhance security coverage and responds to incidents that may arise in these unmonitored areas, making crucial decisions in real-time to maintain security and safety.

The chief of the guard plays a significant role in overall security management, but their focus is often on the guard force rather than specific geographic areas. The commander of the base holds the highest authority but does not directly manage daily patrols. The control officer oversees operations at a broader level but is not necessarily tasked with specific area coverage like the patrol supervisor is. Therefore, the patrol supervisor's direct involvement with patrolling and situational awareness in various parts of the installation makes them the correct answer.
