The U.S. Army relieved Lt. Gen. Charles Costanza of command over V Corps just two months before his tenure was set to end, a move officials say was driven by conduct, not politics.
Costanza, who led the Army's forward-deployed corps from headquarters at Fort Knox, Kentucky, and Camp Kościuszko, Poland, was removed "in recent days," two U.S. officials confirmed. An Army spokesperson said the matter was "referred to the appropriate authority in accordance with Army regulations" but offered no further detail on what prompted the action.
One source familiar with the removal told The Hill the decision stemmed from "conduct that would get a commander relieved at any level." Two additional sources said the removal was not directed by Defense Secretary Pete Hegseth and was not political in nature. The Army has not disclosed the specific conduct at issue, and Costanza has not commented publicly.
Brig. Gen. John B. Mountford, the deputy commanding general of readiness for V Corps, will serve as acting commanding general. Maj. Gen. Thomas Feltey, who previously led the 1st Cavalry Division at Fort Hood, Texas, was nominated for promotion to lieutenant general last month and is scheduled to assume command of V Corps at Fort Knox in October.
Costanza's removal stands apart from Hegseth's broader leadership overhaul
More than two dozen senior military officers have been removed or sidelined under Hegseth's Pentagon leadership. Those dismissals have drawn sharp criticism from Democrats and some Republicans who view them as politically motivated purges. Hegseth previously removed Army Chief of Staff Gen. Randy George and Gen. Chris Donahue, commander of U.S. Army Europe and Africa.
But sources drew a clear line between Costanza's case and those broader personnel changes. If the sources are accurate, this removal followed the traditional military accountability process, a commander was relieved for conduct, not ideology. That distinction matters at a moment when every Pentagon personnel decision is viewed through a political lens.
Costanza holds a master's degree in military studies from American Military University. Before taking command of V Corps, he served as deputy commanding general of U.S. Army Europe, Africa and, before that, as commanding general of the 3rd Infantry Division at Fort Stewart, Georgia. His career record made the abrupt removal all the more conspicuous.
The Army has not identified who constitutes the "appropriate authority" now reviewing the matter or what timeline that review might follow. Costanza was reached for comment but did not respond, according to The Hill's reporting.
Poland troop deployment remains stalled months after Trump's announcement
Costanza's departure comes against the backdrop of an unfulfilled commitment to bolster American military presence in Poland. The Pentagon canceled a planned deployment of the Army's 2nd Armored Brigade Combat Team, 1st Cavalry Division to Poland in May. President Trump then announced the U.S. would send 5,000 troops to Poland later that same month.
Months passed. Poland's Defense Minister Władysław Kosiniak-Kamysz said in June that the return of U.S. service members would materialize "in the 'coming weeks.'" By late July, those weeks had come and gone with no brigade on the ground.
Rep. Don Bacon, a Nebraska Republican on the House Armed Services Committee, told The Hill the deployment still had not happened:
"They're sitting down. They're trying to wait them out or something. I don't know what they're doing."
Bacon's frustration is worth noting. He is not a reflexive Pentagon critic or an anti-administration voice. He is a retired Air Force brigadier general and a reliable supporter of a strong defense posture, exactly the kind of lawmaker whose patience signals a real problem, not a partisan talking point.
The broader pattern of leadership turnover at the top of Army commands in Europe has raised practical questions about continuity. V Corps is not a stateside administrative headquarters. It is the Army's primary corps-level command for European operations, with a forward element in Poland, a NATO ally sharing a border with Ukraine and sitting within range of Russian military pressure.
Removing a three-star general from that command, even for legitimate conduct reasons, creates a gap. Mountford holds the fort as acting commander, but the permanent replacement does not arrive until October. That leaves a corps responsible for coordinating Army operations across Europe under interim leadership for roughly two months, the same two months Costanza would have served had he not been relieved.
Accountability cuts both ways, and that is the point
Hegseth's Pentagon has moved aggressively to reshape military leadership. The secretary has cleared out legacy advisory boards and removed senior officers he viewed as misaligned with the administration's priorities. Critics have framed those moves as ideological housecleaning. Supporters see them as overdue course corrections after years of institutional drift.
Costanza's case does not fit neatly into either narrative. Two sources explicitly said this removal was not directed by Hegseth and was not political. If that holds, it suggests the Army's own chain of command identified a problem and acted, which is exactly how military accountability is supposed to work.
That should be welcome news for conservatives who have long argued that military leadership needs higher standards, not lower ones. The Army's recent moves to tighten internal accountability processes reflect the same principle: commanders who fail to meet the standard should face consequences regardless of rank or timing.
Still, the silence around the specifics is a problem. The Army confirmed the removal, named the replacements, and cited regulations, then stopped talking. The public does not know what Costanza did. The Army has not said whether the conduct was criminal, ethical, or administrative in nature. "Referred to the appropriate authority" is bureaucratic shorthand that answers nothing.
Taxpayers fund a three-star general's salary, staff, housing, and command authority. When that authority is revoked weeks before a scheduled transition, the public deserves more than a one-line statement and a referral to unnamed regulators. Accountability without transparency is just a personnel action.
Meanwhile, the Poland deployment question lingers. The Pentagon's ongoing reshaping of military promotions and leadership has consumed enormous institutional energy. Whether that energy has come at the cost of operational follow-through, getting 5,000 troops to a frontline NATO ally as promised, is a question that deserves a straight answer, not a shrug from a Republican congressman who cannot get one.
When the military holds its own accountable for misconduct, that is the system working. When it cannot explain why or deliver on its own commitments, that is the system asking for trust it has not yet earned back.
