What establishes duties, roles, and responsibilities at individual assignments, checkpoints, gates, and guard posts?

The correct answer is Post Orders. Post Orders are critical documents used in physical security that specifically outline the duties, roles, and responsibilities for security personnel at various locations such as individual assignments, checkpoints, gates, and guard posts. These orders provide clear and detailed guidance on what a security officer is expected to do, including their specific tasks, procedures to follow in various situations, and protocols for reporting and communication.

By defining expectations in a structured manner, Post Orders ensure that security personnel are aware of their responsibilities and can perform their roles effectively and consistently, which is essential for maintaining safety and security at a facility. This level of specificity helps prevent misunderstandings and provides a framework for accountability among security staff.

While guidelines, regulations, and standard procedures contribute to the broader scope of security practices, they do not provide the same level of detail for individual roles and specific positions as Post Orders do. As such, Post Orders are essential for effective physical security planning and implementation.
