Adrianna Douglas US Army Secretary Dan Driscoll resigned on Monday after discussing the service with the president. His exit follows other leadership shake-ups, including the firing of Army Chief of Staff Gen. Randy George. Their departures raise questions about the future of the Army's sweeping transformation. With the resignation of Secretary of the Army Dan Driscoll, the US Army has lost another top leader who was driving its sweeping transformation for future wars. As the service secretary, Dan Driscoll was a leading figure in reshaping the Army's relationship with industry and accelerating its focus on drone warfare. His departure, along with the dismissal of the service's top general earlier this year, has left the Army's modernization efforts in question.
