Title 10 › Subtitle A — General Military Law › PART I — ORGANIZATION AND GENERAL MILITARY POWERS › CHAPTER 6 — COMBATANT COMMANDS › § 164
The President may only pick an officer to lead a unified or specified combatant command if that officer has the required joint specialty and has finished a full tour as a general or flag officer in a joint duty assignment. The President can waive those requirements if it is needed for the national interest. If the President removes or moves such a commander before their expected time ends, the President must tell Congress, including the defense committees, within five days and explain why. This does not stop other personnel actions allowed by law. A combatant commander answers to the President and the Secretary of Defense for the missions they are given. Under the President’s direction, the commander works under the Secretary of Defense and must keep the command ready. Major duties are to make plans to use the armed forces, help deter conflict, and command forces when ordered. Unless told otherwise, the commander can give orders, set the chain of command, organize and use forces, assign tasks to subordinates, approve needed administration and support, pick subordinate commanders and staff (and suspend them or start courts-martial as allowed), and set communication rules. The Secretary of Defense must give commanders enough authority to do their job and regularly review what authority they need after consulting others. If a commander thinks they lack needed authority, they must tell the Secretary of Defense right away. The commander must agree to most picks for subordinate commanders and staff and must evaluate subordinate commanders and send those evaluations to the service Secretary and the Chairman of the Joint Chiefs. For geographic commands that include the United States, at least one deputy must be a reserve officer eligible for promotion to lieutenant general (or vice admiral in the Navy) or a Space Force officer with prior active space service and promotion eligibility, unless the commander is a reserve officer or a qualifying Space Force officer. The commander may suspend officers and recommend reassignment under Defense Department procedures and must give the Chairman of the Joint Chiefs of Staff any information needed for the Chairman’s duties.
