Gen. Chris Donahue, a prominent four-star Army general known for his leadership in multiple combat operations, is set to relinquish his command of U.S. Army Europe in a ceremony scheduled for July 2 in Germany, according to sources familiar with the matter. The move abruptly ends Donahue’s tenure as the Army’s top commander on the continent, where he played a key role in revamping NATO’s defense posture against Russian aggression and supporting Ukraine.

Donahue’s departure comes amid a broader shake-up within the Pentagon’s senior leadership driven by Defense Secretary Pete Hegseth. Pentagon officials say the changes reflect an ongoing effort to reduce the overall number of flag officers by 10% and cut four-star billets by 20%. However, some lawmakers and former military officials interpret the shift as a politically motivated attempt to sideline officers with extensive battlefield and command experience in favor of personnel aligned more closely with Hegseth’s agenda.

Sen. Jeanne Shaheen (D., N.H.), a member of the Senate Armed Services Committee, called the decision “unfortunate” and emphasized Donahue’s crucial role in interpreting lessons from the Ukraine conflict. Despite advocacy from some lawmakers and Army officials to secure Donahue another senior command, Pentagon sources indicate that he submitted retirement papers at the Defense Department's request. It remains uncertain whether he will retain his four-star rank in retirement, as this would require a formal waiver. The Pentagon declined to comment on the personnel decisions.

Donahue, a West Point graduate with a distinguished career, rose to four-star rank in 2024 and had previously commanded the 82nd Airborne Division during the 2021 evacuation of U.S. personnel and Afghan allies from Kabul. Although he was integral in restoring security during the withdrawal, he was not responsible for the security lapses at Abbey Gate, where a suicide attack killed 13 U.S. service members. Earlier in his career, Donahue led Delta Force operations against Islamic State militants in Iraq and Syria and commanded the Army’s XVIII Airborne Corps, contributing to Ukraine’s 2022 counteroffensives. His European post, elevated to four-star status during the Trump administration, also includes command over NATO’s land forces.

The personnel changes under Hegseth have sparked controversy within the military community, with reports of numerous blocked promotions affecting female and Black officers and concerns about retribution for officers holding dissenting political views. Pentagon insiders detail that Hegseth’s decision-making process involves a close circle of advisers evaluating senior officers on subjective measures including loyalty to the current administration and prior association with diversity and inclusion policies. An internal Pentagon review reportedly included a binder of candidates for key commands, with Hegseth selectively endorsing officers perceived as politically favorable, sometimes overruling service chiefs’ recommendations.

Hegseth’s office declined to comment on the personnel shifts, and the acting Pentagon press secretary emphasized that no remarks would be made on pre-decisional matters. Maj. Gen. Christopher Norrie, Donahue’s deputy, is expected to assume command duties following his departure.

The shake-up exemplifies ongoing tensions between Pentagon leadership and career military officers amid a shift toward politicized personnel management at the highest ranks of the U.S. military.
