What are the most important written instructions for the security guard called?

Post orders are the most important written instructions for security guards as they provide specific guidance on their duties and responsibilities while on a particular post. These instructions outline the detailed procedures and protocols that guards must follow, including how to respond to incidents, the rules for interacting with personnel and visitors, reporting procedures, and any particular attention areas they need to monitor.

The significance of post orders lies in their role in ensuring consistency and compliance in the execution of security protocols, allowing guards to understand their specific roles within the broader security framework. Additionally, well-written post orders serve as a reference that guards can rely on during their shifts, helping to mitigate confusion and enhance overall effectiveness in securing the premises.

On the other hand, while memoranda may communicate important announcements, and operational or staff orders might govern broader operational aspects or administrative functions, they do not provide the specific, actionable instructions needed at a guard's designated post, which is why post orders are critical for day-to-day operations in security settings.
