US Army Secretary Dan Driscoll has submitted his resignation after 18 months in the role, adding another abrupt departure to a Pentagon already shaken by leadership removals and reported internal power struggles.
The White House confirmed on Monday, 31 August, that Driscoll was stepping down but gave no official reason. His departure followed months of reports describing tension with Defense Secretary Pete Hegseth over Army modernisation, readiness and the removal of senior commanders.
