AF Form 4377 Events Log: Download & Guide | USAF Command Post – The AF Form 4377, officially titled Events Log, is a standardized U.S. Air Force form used primarily by Command Posts (CPs) and other operational units to maintain a detailed chronological record of significant events, activities, incidents, and operational occurrences. It serves as an official, auditable log that supports mission monitoring, command and control (C2), emergency actions, operational reporting, and after-action reviews.
This form ensures accountability, provides a historical record for investigations or inspections, and helps shift personnel maintain situational awareness during daily operations, exercises, or real-world contingencies.
Why AF Form 4377 Matters in the Air Force?
Command Posts act as the nerve center for installation-level C2. They process Emergency Action Messages, relay command directives, handle operational reports (such as AF OPREP-3), and support readiness tracking. A well-maintained events log is essential for these functions.
According to AFMAN 10-207 (Command Post Operations), all Command Posts must maintain a daily events log using AF Form 4377 (or MAJCOM-prescribed alternative media). Logs typically open at 0001Z and close at 2359Z each day. This creates a consistent, time-stamped record that documents:
- Controller on-duty shifts and changeovers
- Checklist completions
- Incoming/outgoing communications
- Significant incidents or emergencies
- Exercise or training events
- Resource status updates
- Any other notable occurrences that impact operations or safety
In scenarios like loss of connectivity or contingency operations, the AF Form 4377 provides a reliable manual backup for logging events that can later support safety investigations, wing inspection teams, or after-action reports.
Proper use of the form supports the 1C3 career field (Command Post) core competencies: mission monitoring/management, emergency actions, emergency management, and operational reporting.
Who Uses AF Form 4377?
- Command Post controllers (primary users, including junior and senior controllers)
- Wing Operations Centers (WOC) and Emergency Operations Centers (EOC)
- Other units involved in C2, airfield management, security forces, or contingency response
- Personnel in training or qualification programs for controller positions
The form is particularly important during shift handovers, where incoming controllers review the log to understand ongoing situations.
How to Use and Fill Out AF Form 4377?
AF Form 4377 is designed as a simple, chronological log sheet. While the exact block layout is detailed in the official PDF (available via the link below), typical entries include:
- Date and Time (in Zulu or local time, consistently applied)
- Event/Incident Description (clear, factual, concise narrative)
- Personnel Involved (names, ranks, positions, or units)
- Actions Taken or notifications made
- Results/Resolution or follow-up required
- Controller Initials or signature for accountability
Best practices for entries:
- Be factual and objective — avoid opinions.
- Use military time and standard abbreviations where appropriate.
- Document everything that could affect operations, safety, or reporting requirements.
- Ensure legibility, especially for manual entries.
- Review and close out the daily log properly at shift end.
Training for new controllers often includes specific instruction on events log procedures as part of Initial Qualification Training (IQT), Mission Qualification Training (MQT), and Continuation Training (CT). Mastery of the events log is considered a basic controller skill.

Common Questions About AF Form 4377
Is AF Form 4377 only for Command Posts?
Primarily yes, but it may be used by other C2 or operations elements (e.g., WOC/EOC during contingencies) as directed by local instructions.
Can it be maintained electronically?
AFMAN 10-207 allows MAJCOMs to prescribe alternative media, but the paper/form version remains the standard for many units, especially as a backup.
How long should logs be retained?
Follow the Air Force Records Disposition Schedule (managed under AFI 33-322 / DAFI 33-322). Consult your unit records manager for specific retention periods.
What if I make a mistake on the form?
Use standard correction procedures (single line through error, initial, and add correct information) unless your unit has a specific policy.
Tips for Air Force Personnel
- Treat every entry as potentially reviewable by inspectors, investigators, or higher headquarters.
- During high-tempo operations or exercises, prioritize timely and accurate logging.
- Use the events log as a tool for continuity — it helps prevent loss of critical information during shift changes or personnel turnover.
- Incorporate log review into daily shift checklists.
For the most up-to-date instructions, always refer to the latest version of AFMAN 10-207 and your MAJCOM or wing supplements, available through the official Air Force e-Publishing website at https://www.e-publishing.af.mil/.
