AFTER-ACTION REVIEW (AAR) 1 After-Action Review “We must continue to look critically at our abilities to achieve decisive victory and aim to improve. I believe that one of the single most important innovations of the past 20 years...one of the keys to our edge today...is the After-Action Review. At all levels, the AAR provides us an honest appraisal of our performance and directs our efforts to correct shortcomings.” General Gordon R. Sullivan, CSA ( Ret)
