An important aspect of professional mastery is the level of competence displayed by individuals, combat teams, headquarters, formations and units. One way we develop our professional mastery is through the conduct of collective training activities.

The after action review (AAR) is an effective tool we can use to ensure that we get the maximum benefit from each of these activities.
