The Pentagon is convulsing. Defence Secretary Pete Hegseth has ordered the removal of seven more high-ranking military officers, bringing the total of senior brass sidelined under his tenure to roughly ten per cent of the military’s top tier, according to officials briefed on the matter.
The shake-up has cleaved the Defence Department’s senior leadership, with some of the remaining officials expressing alarm at the pace and scope of the purges. One consequence was made public on Thursday: the Army’s civilian secretary, a frustrated figure who had grown exasperated with Hegseth’s campaign against the general ranks, has tendered his resignation.
The exits mark an extraordinary moment of upheaval inside an institution that prizes continuity and hierarchy. Hegseth, a former Fox News host with no prior Pentagon experience before his confirmation earlier this year, has made clear he intends to reshape the senior officer corps in his own image. Allies say he is draining the swamp. Critics inside the building say he is gutting expertise at a moment of global volatility.
A Campaign of Retirements and Firings
The seven officers targeted in the latest round represent a cross-section of the military’s command structure, the officials said, speaking on condition of anonymity to discuss internal personnel matters. They include generals and admirals whose careers span three or four decades of service, many of whom were considered leading candidates for four-star command before Hegseth began his review.
Taken together with earlier moves, the defence secretary has now forced out — through retirement, reassignment or outright dismissal — dozens of flag officers. The figure is striking because it suggests a deliberate strategy rather than a routine housecleaning. Hegseth has spoken openly about his desire to install a new generation of leaders, ones more aligned with his views on warrior culture, physical fitness and what he calls “mission first” thinking.
It is not the language of a typical Pentagon chief. It is the language of a disruptor.
The Secretary Who Walked Away
The Army secretary’s resignation is perhaps the most telling consequence. A civilian appointee, his role was to serve as the senior policy overseer for the Army and to bridge the gap between Hegseth’s office and the uniformed service chiefs. That he chose to leave — rather than attempt to ride out the turbulence — speaks to the depth of the disquiet inside the building.
“He wasn’t thrown out,” one official said. “He was just done.”
His departure leaves the Army without a confirmed civilian leader at a moment when the service is wrestling with recruiting shortfalls, modernisation delays and an ambitious reorganisation plan that Congress has only partially funded. The vacancy will almost certainly complicate Hegseth’s efforts to push through additional changes, since the Army secretary typically plays the central role in shepherging the service’s priorities through Capitol Hill.
Pentagon in Turmoil
Inside the Defence Department, the mood has soured. Officers who once assumed their careers would follow predictable trajectories now speak of uncertainty and suspicion. Some have begun quietly updating résumés. Others have requested meetings with career counsellors, an unusual step for officers at the general and flag ranks.
The friction extends beyond personnel. Hegseth’s team has clashed with career officials over a range of policy decisions, including the handling of ongoing operations in the Middle East, the pace of aid deliveries to Ukraine, and a controversial review of military justice procedures that critics say could weaken protections for service members.
Senator Jack Reed of Rhode Island, the senior Democrat on the Armed Services Committee, said in a statement that the turnover “raises serious questions about civilian control of the military and the loss of experienced leadership at a dangerous moment.”
A defence official, granted anonymity to discuss internal deliberations, was blunter: “We’ve never seen anything like this. Not even close.”
The Pushback
Hegseth has allies in the White House and on Capitol Hill who view his efforts as long overdue. They argue that the senior officer ranks have grown complacent, that promotion has too often reflected political correctness rather than battlefield competence, and that a forceful shake-up is exactly what the military needs after decades of drift.
The defence secretary himself has not publicly addressed the latest round of firings or the Army secretary’s resignation. But in recent interviews he has insisted that his changes will produce a leaner, more lethal force. “We’re not going to apologise for demanding excellence,” he said last month on a conservative radio programme.
Privately, though, even some of his supporters acknowledge that the speed of the upheaval is taking a toll. Morale in some units has dipped. Retention bonuses, once considered a sure thing for experienced officers, are now being negotiated more cautiously. And the institutional knowledge walking out the door — the hard-won lessons of two decades of counterinsurgency, of great-power competition, of cyber warfare — cannot simply be replaced.
A Building Divided
The Defence Department is now functionally split into two camps. On one side are Hegseth’s loyalists, many of them young political appointees who arrived with him from the world of cable news and conservative activism. On the other are career officials, uniformed and civilian, who view the changes with mounting alarm.
The two sides barely talk, according to one Pentagon staffer. “It is like working in two different buildings,” the person said.
That division is now beginning to attract the attention of outside observers. Analysts at the Centre for Strategic and International Studies and the RAND Corporation have published papers warning that excessive turnover at the senior ranks risks degrading operational readiness. Former defence secretaries from both parties have privately urged caution.
It is not clear that Hegseth is listening.
Why it Matters
The removal of seven additional flag officers, on top of the roughly ten per cent of senior military leaders already forced out, is not a routine reshuffle. It is a structural assault on the leadership of the United States armed forces — carried out at a moment of multiplying global crises, from the war in Ukraine to mounting tensions with China in the Pacific. The resignation of the Army’s civilian secretary suggests that even those inside the system who might have been expected to defend it have concluded that the institution they served no longer functions as it should. If Hegseth continues at this pace, the question will not be whether the Pentagon is being remade. It will be what is being remade, and at what cost to the readiness of the world’s most powerful military.
