What type of document is used to document daily events that occur on post?

The preferred document for documenting daily events that occur on post is the DHS form 1103. This specific form is designed to serve as a daily log for the observations and activities of security personnel. It allows officers to record various incidents, routine occurrences, and any other significant events that take place during their shift. This documentation is crucial for maintaining a record of activities that can be referenced for future investigations, audits, or operational reviews.

The other forms listed are not specifically intended for daily event logging. While they may serve other purposes within the scope of security operations and administrative processes, the DHS form 1103 is explicitly tailored for capturing the day-to-day occurrences, making it the most appropriate choice for this particular need.
