What is the role of the Marine Corps Center for Lessons Learned (MCCLL)?

• A. The Marine Corps Center for Lessons Learned actively collects, analyzes, publishes and archives lessons learned materials including AARs and Marine Corps lessons learned reports.
• B. The Marine Corps Center for Lessons Learned only archives AARs.
• C. The Marine Corps Center for Lessons Learned serves as a training academy for mishap investigators.
• D. The Marine Corps Center for Lessons Learned operates the safety office for every installation.

Answer: (A)

The essential role of the Marine Corps Center for Lessons Learned is to turn experiences into usable knowledge across the Marine Corps by actively collecting After Action Reviews and other lessons learned materials, analyzing them to identify trends and root causes, publishing the findings, and archiving the materials so units can access them later. This makes lessons learned more than just records; it creates a centralized, searchable repository that supports learning, improvements in training and procedures, and safer operations across the enterprise. The center does not simply archive AARs, nor is it a training academy for mishap investigators or a safety office for every installation; its purpose is to facilitate broad, ongoing dissemination and analysis of lessons learned to prevent repeat mistakes and enhance readiness.
