Lt. Gen. Charles Costanza, a high-ranking U.S. Army general overseeing American forces and military operations across the European continent, has been abruptly removed from his command. The decision comes nearly two months ahead of his anticipated departure, with Army officials offering no public explanation for the sudden change. Costanza, who had commanded the Army’s V Corps since April 2024, was expected to leave his position in October.
An Army spokesperson confirmed Costanza’s removal in recent days, stating that Brig. Gen. John B. Mountford, V Corps’ deputy commanding general for readiness, is now temporarily serving as acting commanding general. This interim appointment precedes the previously confirmed takeover by Maj. Gen. Thomas Feltey, Costanza’s designated successor, whose Senate confirmation for the role had already been secured. The unexplained acceleration of Costanza’s departure has drawn attention given the critical nature of his command.
V Corps holds a significant and increasingly prominent role in American military strategy, particularly in the context of ongoing geopolitical tensions in Europe. The corps is responsible for coordinating U.S. Army forces and operations throughout Europe, maintaining a crucial forward presence in Poland. Its responsibilities have expanded considerably following Russia’s invasion of Ukraine, encompassing coordination of American military support for Kyiv and management of the U.S. Army’s presence along NATO’s eastern flank. The timing of Costanza's early removal, therefore, coincides with a period of heightened strategic importance for the region.
The abrupt change in leadership also occurs amid a broader shake-up within America’s senior military ranks under Defense Secretary Pete Hegseth. More than two dozen high-ranking military officers have reportedly been removed or sidelined during Secretary Hegseth’s tenure, often without detailed public explanations for individual decisions. However, a source familiar with Costanza’s removal informed ABC News that this specific decision was unrelated to Hegseth’s broader efforts to reshape the military’s senior leadership and did not involve political considerations. No alternative explanation for the early removal was provided.
The Trump administration has also recently made adjustments to the American military footprint in Europe. Earlier this year, the Pentagon downsized its presence, including the abrupt cancellation of a planned deployment of the Army’s 2nd Armored Brigade Combat Team, 1st Cavalry Division, from Fort Hood, Texas, to Poland. This cancellation prompted criticism from Warsaw. Subsequently, President Donald Trump announced that the U.S. would position 5,000 troops in Poland, signaling a shifting but continued commitment to the region.
Lt. Gen. Costanza, an experienced armor officer, had served more than two years leading V Corps, assuming command in April 2024. Prior to that, he commanded the 3rd Infantry Division at Fort Stewart, Georgia. His unexpected early departure adds another senior officer to the growing list of military leadership changes under Secretary Hegseth. While a leadership transition for V Corps was already anticipated with Maj. Gen. Feltey’s confirmed appointment in October, the Army has not publicly clarified why Costanza was removed approximately two months before his scheduled handover.
As Brig. Gen. Mountford assumes acting command of V Corps, the U.S. military’s operations in Europe continue, with a focus on supporting allies and maintaining stability. The lack of public explanation for Lt. Gen. Costanza's early removal, however, leaves questions regarding the specific circumstances that led to the premature end of his command at a pivotal time for European security.
