Which document outlines the operational procedures for harbor patrol units?

The document that outlines the operational procedures for harbor patrol units is CNICINST 5530.5. This instruction provides guidance specifically related to the management, organization, and operations of naval security forces, including harbor patrol operations. It details the responsibilities and procedures necessary to ensure security and safety within harbor areas, making it essential for those involved in maritime security and law enforcement.

Other options, while they may pertain to naval operations or training, do not specifically address harbor patrol unit procedures. NAVEDTRA 14137B focuses on training manuals, OPNAVINST 5530.14 relates to force protection and is broader in scope, and NTTP typically covers tactical procedures for naval operations, without honing in on harbor patrol specifics. Hence, CNICINST 5530.5 is the appropriate document for the operational procedures needed in this context.
