Defense Secretary Pete Hegseth on Thursday asked U.S. Army Chief of Staff Gen. Randy George to step down and retire effective immediately, a Pentagon official told Military Times.

The abrupt move, one of three significant changes made by Hegseth the same day, cuts short George’s tenure, which began in September 2023, well before the end of the typical four-year term.

The Pentagon intends to replace him with a leader aligned with Hegseth and President Donald Trump’s vision for the Army, the official added. They did not specify what this vision entails.

George has more than four decades of military service, according to the Army. He was commissioned as an infantry officer from the U.S. Military Academy at West Point in 1988 and served in the Gulf War, with subsequent deployments in Afghanistan and Iraq.

Chief Pentagon spokesman Sean Parnell said that the current vice chief of staff of the Army, Gen. Christopher LaNeve, will replace George on an interim basis.

Parnell asserted that LaNeve is “a battle-tested leader with decades of operational experience and is completely trusted by Secretary Hegseth to carry out the vision of this administration without fault.”

The Department of Defense said it “has nothing further to provide at the moment.”

Hegseth on Thursday also removed Gen. David Horne, a former Army Ranger who had been overseeing the Army’s Transformation and Training Command, and Maj. Gen. William Green, the Army chief of chaplains, a Pentagon official confirmed to Military Times.

Since taking office, Hegseth has fired over a dozen generals and admirals, including Chairman of the Joint Chiefs of Staff Gen. C.Q. Brown and Chief of Naval Operations Adm. Lisa Franchetti.

The latest shakeup coincides with the Pentagon’s deployment of thousands of troops from the Army’s elite 82nd Airborne Division to the Middle East, as the war with Iran enters its fifth week.

The ouster was first reported by CBS News.
