What is the term for a professional verbal discussion of a unit's actions immediately after a mission?

The term that describes a professional verbal discussion of a unit's actions immediately after a mission is "After Action Review." This process is critical for gathering insights on what happened during the mission, evaluating the effectiveness of actions taken, and identifying lessons learned. The aim is to improve future performance and readiness by analyzing both successes and areas for improvement. After Action Reviews foster open communication among team members and encourage a learning culture within the organization.

While mission briefings typically occur before an operation to inform participants of the objectives and strategies, they do not focus on the reflection and analysis of completed actions. Debriefing sessions can also imply a review of the mission, but they are generally more informal and might not always incorporate structured feedback. Performance evaluations often assess individual or team effectiveness over a longer period rather than immediately after a specific mission. Thus, the After Action Review is the most accurate term for the context provided in this question.
