Under what conditions can resource control measures be enacted by U.S. forces?

• A. The requirements are clearly beyond the capabilities of the HN's security forces
• B. The HN has requested assistance
• C. Appropriate U.S. authorities (to include U.S. Ambassador) have granted approval
• D. All of the above

Answer: (D)

Resource control measures by U.S. forces require a combination of three conditions: there must be a demonstrated capability gap in the host nation’s security forces that justifies action, the host nation must have requested or consented to assistance, and formal approval must be obtained from the appropriate U.S. authorities, including the U.S. Ambassador. This ensures the action is necessary, authorized, and legitimate within both diplomatic and military authority. The host-nation request respects sovereignty and aligns with the mission’s scope, while ambassadorial approval provides the necessary diplomatic clearance and interagency coordination. If any one of these elements is missing, the action should not proceed.
