What is the primary purpose of an after-action review (AAR)?

The primary purpose of an after-action review (AAR) is to analyze what happened during an operation or training event and to identify lessons learned. AARs are conducted after missions or exercises to reflect on the performance of individuals, teams, and units, assessing what went well and what could be improved. This process promotes continuous learning and enhances future performance by fostering an environment where feedback is welcomed, and constructive criticism is encouraged.

The focus on extracting valuable insights ensures that both successes and areas needing improvement are captured, thereby enabling personnel to make informed decisions in the future, adapt strategies, and enhance overall effectiveness. This contrasts with the other choices, which do not align with the primary goal of an AAR. Summarizing financial expenditures, documenting personnel attendance, or creating new training manuals are important functions but not the central aim of an after-action review.
