Operational Commands (OCs) typically use three techniques to organize their After Action Reviews (AARs): thematic organization, chronological organization, and issue-based organization. Thematic organization groups findings by key themes or objectives, allowing for a focused discussion on specific areas of performance. Chronological organization follows the sequence of events during the operation, providing a timeline for analysis. Issue-based organization centers around specific problems or challenges encountered, facilitating targeted solutions and lessons learned.
