One of the Army’s most seasoned and high-profile officers is abruptly leaving the service and is expected to announce his retirement as soon as Wednesday.

Axar.az reports, citing ABC News, Gen. Chris Donahue has spent the past 18 months leading U.S. Army Europe and Africa, the command responsible for Army operations across both continents.

Donahue is expected to relinquish his command at a change of command ceremony to be held next week, according to U.S. official.

His departure comes as Defense Secretary Pete Hegseth presses ahead with a sweeping overhaul of the Pentagon’s senior ranks, firing or sidelining large numbers of top officers with little public explanation, including the Army’s top officer Gen. Randy George.
