Summary

The President chooses a Vice Chairman of the Joint Chiefs of Staff and the Senate must approve. The Vice Chairman must be an officer from the regular armed forces. The Chairman and Vice Chairman normally cannot be from the same service, but the President can temporarily waive that rule to allow an orderly transition. The Vice Chairman serves one four-year term that starts on October 1 of an odd-numbered year and cannot start in the same year as the Chairman’s term; in time of war the President may reappoint them without limit. While serving, the Vice Chairman cannot be promoted to Chairman or to another armed forces position unless the President waives that rule for the national interest. The Vice Chairman must have the joint specialty required by law and must have completed a full tour as a general or flag officer in a joint duty assignment, though the President may waive these requirements for national interest. The Vice Chairman does Joint Chiefs duties and other tasks given by the Chairman with the Secretary of Defense’s approval. If the Chairman is absent or the job is empty, the Vice Chairman acts as Chairman until a replacement or the Chairman returns. If both jobs are empty or both are absent, the President names another Joint Chiefs member to act as Chairman. The Vice Chairman holds four‑star rank (general or admiral) and outranks other officers except the Chairman, but does not have military command over the Joint Chiefs or the armed forces.
