The U.S. Army removed its top operational commander in Europe weeks before his scheduled departure, and has declined to say why, even as the Pentagon reshapes military leadership across the board.

Lt. Gen. Charles Costanza, who has led V Corps since 2024, was relieved of command "in recent days," an Army spokesperson confirmed to The Express. The spokesperson did not detail what led to the removal. Maj. Gen. Thomas Feltey, who was already slated to take over V Corps in October, has stepped into the role roughly two months ahead of schedule.

The abrupt change comes during a period of significant upheaval at the Pentagon, where more than a dozen high-ranking officers have been removed or demoted under Defense Secretary Pete Hegseth. But a source familiar with the situation told ABC News that Costanza's removal is unrelated to Hegseth's broader effort to reshape the military, including the push to sideline officials associated with past administrations or those not aligned with the Trump administration.

If that is true, the Army owes the public a better answer than silence. A three-star general running the service's most strategically important forward command does not get pulled off the job two months early for no reason, and the refusal to explain invites exactly the kind of speculation the Pentagon says it wants to avoid.

V Corps sits at the center of NATO's eastern flank

V Corps is not a backwater assignment. The command is responsible for coordinating U.S. Army forces and operations across Europe and is partially based in Poland. It grew far more prominent after Russia's invasion of Ukraine, when the unit helped coordinate American support for Kyiv and managed the U.S. military presence along NATO's borders.

Costanza himself was directly involved in high-stakes operations during his tenure. When four U.S. Army soldiers from the 1st Brigade, 3rd Infantry Division went missing during a training exercise near Pabradė, Lithuania, their M88 Hercules armored recovery vehicle later found submerged in a body of water, Costanza issued a public statement thanking Lithuanian forces and first responders for their aid in the search.

That incident, in which NATO Secretary General Mark Rutte initially said the soldiers had died before the alliance walked back the claim, underscored the dangers U.S. troops face in forward-deployed positions across Eastern Europe, and the weight of the command Costanza held.

Pentagon downsizing in Europe adds friction with allies

Costanza's removal lands against a backdrop of broader changes to America's military posture on the continent. The Pentagon began downsizing its European footprint this year, a process that included the sudden cancellation of a planned deployment of the Army's 2nd Armored Brigade Combat Team and 1st Cavalry Division to Poland.

That cancellation rattled Polish leaders, who described their country as a "model ally" and questioned why Washington would pull back forces from a nation that has consistently met its NATO defense-spending commitments. The friction was significant enough that President Trump moved to address it directly, announcing the U.S. would position 5,000 troops in Poland.

Polish President Karol Nawrocki welcomed the move with a statement that read more like a diplomatic thank-you note than a policy response:

"Good alliances are those based on cooperation, mutual respect, and a commitment to our shared security. I thank U.S. President Donald J. Trump for his friendship toward Poland and for the decisions whose practical dimension we see very clearly today."

Nawrocki's careful, appreciative tone suggests Warsaw understands the value of staying in the administration's good graces, and the cost of being seen as an unreliable partner at a moment when the Pentagon is clearly willing to rethink longstanding commitments.

Hegseth's leadership overhaul now exceeds a dozen senior officers

Even if Costanza's removal is genuinely unrelated to Hegseth's reshaping effort, it does not exist in a vacuum. The Defense Secretary has presided over the removal or demotion of more than a dozen high-ranking officers since taking office, a pace of leadership turnover that has drawn attention across the military establishment.

The broader pattern includes other high-profile departures from European commands. Gen. Christopher Donahue stepped down as the top Army commander in Europe after his own removal, part of what has become a sustained effort to install leaders aligned with the administration's defense priorities.

Hegseth's Pentagon has also moved to reshape the military's institutional culture beyond personnel. The War Department recently replaced Ivy League schools with UNC-Chapel Hill and Virginia Tech in its officer fellowship program, a decision that signaled the administration's intent to steer the officer corps away from institutions it views as ideologically hostile.

Supporters of the overhaul argue it is long overdue. The military's senior ranks accumulated officers over multiple administrations whose priorities did not always align with the civilian leadership voters elected. Accountability flows downward from the commander in chief, and a president who believes the Pentagon needs new direction has every right to install leaders who share his vision.

But that argument only holds if the changes are made transparently. When the Army removes a three-star general from a critical command and refuses to say why, while simultaneously insisting the move has nothing to do with the broader leadership overhaul, it creates an information gap that serves no one.

No public statement from Costanza raises more questions

Costanza has not made any public statement regarding his removal, and the Army has offered no indication of whether the decision was disciplinary, administrative, or driven by some other factor. The source who spoke to ABC News ruled out the Hegseth connection but offered no affirmative explanation in its place.

That leaves several open questions. Was there a specific incident or investigation that prompted the early removal? Did Costanza request relief? Was there a disagreement over the European drawdown or the canceled Poland deployment? The Army's silence makes it impossible to know, and impossible for the public to evaluate whether the decision was sound.

Feltey's assumption of command appears to have been a straightforward acceleration of an already-planned transition. He was scheduled to take over in October, and moving that timeline forward by two months is logistically manageable. But the lack of ceremony or explanation surrounding the handover is unusual for a command of this significance, particularly one at the center of America's European defense posture.

The men and women serving under V Corps deserve to know why their commanding general was pulled off the job. So do the allied nations whose security depends on the steadiness of American military leadership in Europe. And so do the taxpayers funding a forward presence that costs billions of dollars a year.

If the Army had a good reason, it should say so. Silence does not project strength, it projects disorder.
