What is the relationship between the supported CCDR and the supporting CCDR in joint operations?

The relationship between the supported Combatant Commander (CCDR) and the supporting CCDR in joint operations is characterized by a collaborative dynamic where each entity has distinct roles that contribute to the overall success of the mission. The correct answer highlights that the supported CCDR is responsible for building requirements that reflect the operational needs and objectives of the campaign or operation. This process involves identifying what resources or support are necessary to accomplish the mission.

Meanwhile, the supporting CCDR provides the necessary support to fulfill those requirements. However, instead of merely reporting them, the supporting CCDR plays an active role in aligning their capabilities and resources to support the objectives set by the supported CCDR. This collaboration is crucial because it ensures that there is a clear understanding of the operational landscape and seamless coordination of efforts between the two commanders. Overall, this relationship underscores the interdependence and teamwork essential for successful joint operations.
