This training circular (TC) is a leader's guide on how to plan, prepare, and conduct an AAR. It supplements and expands the guidance in Field Manual (FM) 25-101. Competent leaders must understand and apply the techniques and procedures which produce good AARs. Key is the spirit in which AARs are given. The environment and climate surrounding an AAR must be one in which the soldiers and leaders openly and honestly discuss what actually transpired in sufficient detail and clarity that not only will everyone understand what did and did not occur and why, but most importantly will have a strong desire to seek the opportunity to practice the task again.
