Defense Secretary Pete Hegseth dismissed Gen. Randy George as the Army’s chief of staff on Thursday, a move military officials indicated reflects intensifying friction between Mr. Hegseth and the service's leadership. General George, appointed in 2023, was credited with guiding the Army through a significant recruiting challenge in 2024 and advocating for the rapid adoption of inexpensive drones and other weaponry that have proven critical in conflicts like the war in Ukraine.

Military officials stated that the strain with Mr. Hegseth did not stem from substantive policy disagreements regarding the Army's strategic direction. Instead, they attributed it to Mr. Hegseth’s long-standing resentments toward the Army, disputes over personnel decisions, and his troubled relationship with Army Secretary Daniel P. Driscoll. General George and Mr. Driscoll had reportedly developed a close working partnership over the past year.

A specific point of contention involved Mr. Hegseth’s directive to block the promotion of four Army officers to brigadier general. Two of these officers are Black and two are women, part of a promotion list predominantly composed of white men. Senior military officials raised questions about whether these officers were being singled out due to their race or gender. Mr. Hegseth had pressed Mr. Driscoll and General George for months to remove the officers, but they consistently refused, citing the officers' exemplary service records. General George sought a meeting with Mr. Hegseth two weeks ago to discuss this issue and concerns about the Defense Secretary's broader involvement in Army personnel matters, but Mr. Hegseth declined the request.

Last week, Laura Loomer, a far-right commentator with ties to Mr. Hegseth and former President Trump, publicly stated on social media that the Defense Secretary was "seriously considering" General George's removal. Ms. Loomer has also criticized Mr. Driscoll. General George also maintained a close relationship with Lloyd J. Austin III, Mr. Hegseth's predecessor.

In addition to General George, Mr. Hegseth also fired Gen. David M. Hodne, who had recently been promoted to lead the Army's Transformation and Training Command, and Maj. Gen. William Green Jr., the Army's chief chaplain. This follows the forced early retirement of Gen. James J. Mingus, the Army's vice chief of staff, last October, a year earlier than anticipated.

Senior Army officers expressed anger and frustration at General George's dismissal, describing it as the latest setback for a service they perceive as being targeted by Mr. Hegseth. General George, known as an innovative combat leader from multiple tours in Iraq and Afghanistan, initiated a "transformation in contact" program to integrate new technologies like drones and artificial intelligence. He also made strategic cuts to programs like the M-10 Booker light tank, investing instead in more agile platforms such as the Infantry Squad Vehicle, and pushed for the expedited development of the M1E3 Abrams tank.

Gen. Christopher LaNeve, Mr. Hegseth's former senior military assistant, is anticipated to succeed General George.
