Lt. Gen. Joseph M. Martin was promoted to general and sworn in as the Army’s vice chief of staff on Friday.

Gen. Mark Milley, the outgoing Army chief of staff, promoted Martin and swore him in as the Army’s 37th vice chief, the Army announced Friday.

Martin was serving as the director of the Army staff. He now replaces Gen. James McConville, who is stepping up to be the 40th Army chief of staff.

McConville will replace Milley, who was confirmed Thursday to become the next chairman of the Joint Chiefs of Staff, making Milley the top uniformed officer in the nation’s military.

“I am humbled and grateful for this tremendous honor,” Martin said on Friday. “I have had no greater privilege than leading and serving with the great men and women of our United States Army, and am truly blessed to be able to continue being by their side as Vice Chief of Staff.”
