Eric Rosenbach, deputy chief of staff of the Defense Department, has been appointed to succeed Eric Fanning as the department’s chief of staff beginning on Monday, DoD News reported Thursday.
Defense Secretary Ashton Carter said he believes Rosenbach “brings the right blend of strategic acumen, technological expertise and managerial skill to help me lead the department during an important time in its history.”
Rosenbach has also worked as the Pentagon’s principal cyber adviser and as assistant secretary for homeland defense and global security.
DoD News reports Fanning will shift to a new role as acting undersecretary of the U.S. Army.
He previously served as undersecretary and acting secretary of the U.S. Air Force, deputy undersecretary of the U.S. Navy and deputy director at the U.S. Commission on the Prevention of Weapons of Mass Destruction Proliferation and Terrorism.
Fanning succeeds Brad Carson and has helped build up DoD’s military and civilian leadership team.
