Lt. Gen. Charles Costanza, commander of the U.S. Army’s V Corps, was removed from his post ahead of schedule, the U.S. Army said on Friday. He had about two months remaining before the planned change of command, ABC News reports.

The reasons for Costanza’s removal have not yet been disclosed. An Army spokesperson confirmed that the general left the post in recent days. At the same time, a source familiar with the situation said the decision is unrelated to Defense Secretary Pete Hegseth’s broader campaign to reshape the senior command structure and has no political motive.

Costanza’s successor, Maj. Gen. Thomas Feltey, had already been confirmed by the Senate for the planned transfer of command, which was supposed to take place in October. Until a new commander is appointed, Brig. Gen. John Mountford is temporarily serving as acting head of the corps.

V Corps is responsible for U.S. ground forces and the coordination of U.S. military operations in Europe. Part of its headquarters is based in Poland. After the start of the conflict in Ukraine, the corps assumed an especially important role, coordinating U.S. support for Kyiv and the activities of American troops on NATO’s eastern flank.

Costanza’s removal came amid broad reshuffling in the top U.S. military leadership. According to ABC News, under Hegseth more than two dozen senior officers have been removed from their posts or relieved of duty, and in many cases the reasons were not publicly explained.

Costanza had led V Corps since April 2024. Before that, he commanded the 3rd Infantry Division at Fort Stewart, Georgia.

The reshuffling is also taking place against the backdrop of a reduction in the U.S. military presence in Europe. In particular, the Pentagon unexpectedly canceled the planned deployment to Poland of the 2nd Brigade Combat Team, 1st Cavalry Division. After criticism of that decision in Warsaw, President Donald Trump said that the United States would station 5,000 troops in Poland.
