What is the title of the U.S. official who normally coordinates standing requirements with the CCDRs?

The Deputy Chief of Mission (DCM) serves as a senior diplomat and is typically the second-in-command at a U.S. embassy. One of their key responsibilities includes coordinating with Combatant Commanders (CCDRs) to align and discuss standing requirements and various operational matters. The DCM acts as a crucial link between the military and diplomatic efforts, ensuring that both domains work seamlessly toward shared objectives.

In this context, the DCM is often tasked with representing U.S. interests abroad and facilitating communication between the embassy and the military presence within the region, which may include handling coordination around strategic requirements set forth by the CCDRs. This role is vital for maintaining cohesive policy implementation and military readiness, especially in areas where the U.S. has military engagements.

In contrast, while other positions like the Ambassador and Secretary of State are involved in broader diplomatic operations and strategy, their primary focus is less on the tactical coordination with military commands. The National Security Advisor, while influential in shaping national security policy, does not hold the direct responsibility for liaising between the embassy and CCDRs on standing requirements. Thus, the DCM is the most appropriate title for the role described in the question.
