Under what circumstance will AAR not be conducted according to standard protocols?

AAR, or After Action Review, is typically conducted to analyze and improve performance following an operation. While various circumstances can complicate or hinder the completion of an AAR, the loss of radio communication specifically affects the ability to share vital information and coordinate a review session effectively. If communication is lost during an operation, it may lead to incomplete insights or reports due to missing perspectives from involved personnel. Without the capacity to engage in discussion and clarify details, the AAR process loses its effectiveness in capturing a comprehensive view of the actions taken and lessons learned.

In contrast, factors such as inclement weather, mechanical failures, or insufficient fuel levels can disrupt operations but do not inherently prevent the AAR from being conducted. The AAR can still occur post-operation as long as there is a means to gather feedback, document issues, and discuss the operation's results, even if certain conditions were less than optimal. Thus, the loss of radio communication directly impedes the collaborative nature of the AAR, making it a unique circumstance that would prevent standard protocols from being followed.
