The After Action Review (AAR) is an interactive discussion intended to help Army units decide what happened during an exercise, decide why it happened, and identify potential corrective actions. An AAR system may facilitate this process by providing aids that portray exercise events (ground truth) from a variety of perspectives. One of the major challenges of an AAR system is that of providing appropriate AAR aids within about ten minutes after exercises conducted in the distributed interactive simulation (DIS) environment. A second challenge is to provide the flexibility necessary to adapt the AAR aids to the results of a specific exercise. The Automated Training Analysis and Feedback System (ATAFS) was developed to help trainers prepare AAR aids as soon as possible after the end of an exercise, by, in part, the application of a knowledge database to support automatic generation of candidate AAR aids. This paper describes the AAR process, the workload of trainers, the ATAFS approach to assisting trainers, and the strengths and shortfalls of this approach.
