<P> There are basically two types of military AARs--formal and informal . Formal AARs require more detailed planning, preparation, and resources . They are normally scheduled and conducted as a part of external and internal evaluations . Informal AARs require less planning and preparation than formal AARs and are often on - the - spot reviews of soldier and collective training performance at crew, squad, or platoon level . </P> <P> Formal AARs are normally conducted at company level and above . However, when a training event is focused at squad or platoon level, and resources are available, a formal AAR may be conducted to gain maximum training benefit . Externally evaluated lane training, small - unit ARTEPs, and tank and BFV gunnery tables are prime examples . Informal crew, squad, and platoon AARs are held prior to company and higher - echelon AARs . </P> <P> The AAR facilitator (evaluator or controller) provides a mission and task overview and leads a discussion of events and activities that focuses on the objectives . The discussion with leaders and soldiers should orient on the use of terrain integration of key BOS (Battlefield Operating Systems), and leader actions . The discussion should also examine the weapons systems and doctrine used by the enemy during the exercise . At the close, the AAR leader summarizes comments from the observers, covering strengths and weaknesses discussed during the AAR and what the unit needs to do to fix the weaknesses . </P> <P> Informal AARs are usually conducted for soldier and crew -, squad -, and platoon - level training or when resources are not available to conduct a formal review . They are often held for lower echelons prior to a formal company - or higher - level AAR, though they may be conducted at company level . Informal AARs are extremely important since they involve all soldiers and leaders in the participating unit . The formal company AARs for the training event depend on these thorough, informal reviews . These are sometimes referred to as a hotwash . </P>
