How was the CJCS Standing ROE developed?

• A. Result of an all-service review and revision of former JCS peacetime ROE.
• B. A unilateral decision by the Chairman of the Joint Chiefs.
• C. From a multinational consortium's guidelines.
• D. From the law of armed conflict.

Answer: (A)

The main idea is that the CJCS Standing Rules of Engagement were created through an all-service review and revision of the former Joint Chiefs of Staff peacetime ROE. This cross-service process brings together input from each military branch, incorporates lessons learned from training and operations, and updates the previous peacetime guidance to reflect current policy, capabilities, and risk considerations. The goal is a single, consistent set of rules that all services apply, rather than separate service-specific ROE. While the Law of Armed Conflict informs what is legally permissible, the Standing ROE themselves come from a coordinated, interservice revision rather than a unilateral decision or external guidelines.
