Which of the following is NOT a chapter in AR 600-20?

The correct answer is based on the content outline of AR 600-20, which covers key aspects of command policies, military discipline and conduct, and the military equal opportunity program. Each of these chapters addresses important elements of military governance and organizational culture.

"Inventory Management" does not fall under the scope of AR 600-20, which is primarily concerned with command structure, leadership dynamics, and the policies governing military personnel and their behavior. This regulation does not encompass logistical functions or specific resource management, which would typically be covered in regulations focused on supply chain management or logistics, rather than command policies. Therefore, the option related to inventory management is not a chapter included in AR 600-20.
