In harbor security operations, what does HSB stand for?

In harbor security operations, HSB refers to "Harbor Security Boat." This designation is crucial for security personnel as it emphasizes the use of specialized vessels designed to patrol and protect harbor areas. The Harbor Security Boat is equipped to enforce security measures, respond to threats, and ensure safe navigation within harbor environments. Understanding this term is essential for Master-at-Arms personnel, as it directly relates to the resources and tactics employed during harbor security operations.

The other terms, while related to harbor security, do not specifically represent the operational vessels used in the field. Hence, they may refer to administrative units, organizational parts, or base facilities within harbor security operations, but they do not encompass the actual boats that perform the patrolling and enforcement duties essential for maintaining the security of harbor areas.
