Which organization is focused on maintaining and executing joint doctrine for the U.S. armed forces?

The Joint Chiefs of Staff (JCS) is the organization specifically focused on maintaining and executing joint doctrine for the U.S. armed forces. It serves as a critical advisory body to the President, the Secretary of Defense, and other senior leaders. The JCS is responsible for developing and integrating joint warfighting concepts and joint operating procedures that guide military operations across all branches of the armed forces. This includes creating guidelines for joint operations and ensuring that all branches can collaborate effectively during missions.

The Unity of purpose and cohesive action among the different military branches is essential for effective defense operations; thus, the role of the Joint Chiefs of Staff in fostering joint doctrine is pivotal. The other organizations mentioned, such as the Unified Combatant Commands, the Defense Logistics Agency, and the military branches themselves, have different and more specific responsibilities that do not center around the development and execution of joint doctrine.
