The director of the Joint Staff (DJS) is a three-star officer who assists the Joint Chiefs of Staff, a cabinet of senior military officers within the United States Armed Forces who advise the secretary of defense and the president on military matters. The director assists the chairman of the Joint Chiefs of Staff in managing the Joint Staff and with the management and organization of the staff's members. The director also chairs meetings of the Operations Deputies, a subsidiary body comprising the director and a three-star delegate from each service who preview or resolve issues before they are escalated to the four-star level of the Joint Chiefs of Staff.[1]
The director of the Joint Staff is selected by the chairman of the Joint Chiefs of Staff, in consultation with the other members of the Joint Chiefs of Staff and subject to the approval of the secretary of defense.[1] As with all three- and four-star positions, the director's appointment is subject to presidential nomination and Senate confirmation.
The position of director is considered one of the most desirable three-star positions in the United States military establishment, for the position has historically served as a stepping stone to a four-star position.[2] As of January 2024, 38 of the 49 past directors and one past acting director, have been promoted to four-star rank. Many of them have been promoted to four-star rank within a year of leaving the position.
The current director of the Joint Staff is Lieutenant General Douglas A. Sims II.
This is a complete list of the Directors of the Joint Staff. An asterisk (*) indicates an acting Director.
Of the 41 Directors of the Joint Staff, 30 have been promoted to four-star rank while on active duty, as has one acting Director; and a 31st former Director was promoted to that rank upon retirement. Moreover, 22 of the last 23 Directors have been promoted to four-star rank within a year of leaving the Joint Staff.
