§164 — Title 10 Armed Forces | U.S. Code

Summary

The President may put an officer in charge of a unified or specified combatant command only if the officer has the required joint specialty and has finished a full tour as a general or flag officer in a joint duty job. The President can waive those rules if needed for the national interest. If the President removes or moves a combatant commander before their tour ends, Congress and the defense committees must be told the reason no later than five days after the change. A combatant commander answers to the President and to the Secretary of Defense. The commander must plan how to use forces, take steps to deter conflict, and lead U.S. forces when ordered. The commander has authority over assigned commands and forces to give orders for operations, training, logistics, organization, employment of forces, and needed administration and discipline. The Secretary of Defense must make sure commanders have enough authority and must review and assign administrative control after talking with military leaders. If a commander thinks they lack authority to do their job, they must tell the Secretary of Defense right away. Subordinate commanders and other Defense elements must follow the combatant commander’s communication and procedure rules for matters the commander controls. Assigning officers to subordinate commands or to the command staff generally needs the combatant commander’s agreement and must follow Defense Department procedures, though the Secretary of Defense can waive that in the national interest. The combatant commander must evaluate direct subordinate commanders and send those evaluations to the military department and the Chairman of the Joint Chiefs of Staff. For commands whose area includes the United States, at least one deputy must be a reserve officer eligible for promotion to lieutenant general (or, for the Navy, vice admiral), or a qualified Space Force officer with prior active space-force service who is eligible for promotion to lieutenant general, unless the commander is already a reserve officer or that kind of Space Force officer. Each combatant command must have a staff with officers from the services that have significant forces there. The commander may suspend and recommend reassigning officers under Defense Department procedures and must give the Chairman of the Joint Chiefs of Staff any information needed for the Chairman’s duties.
