U.S. Pentagon reduces European brigade combat teams, delays Poland deployment

The U.S. Department of War announced on May 19, 2026 that the number of Brigade Combat Teams (BCTs) stationed in Europe will be cut from four to three, returning the force posture to the 2021 level. The decision, communicated by Assistant Secretary of War Sean Parnell on X, was described as the result of a "comprehensive, multilayered process focused on U.S. force posture in Europe" and as part of President Donald Trump's "America First" agenda that encourages NATO allies to assume greater responsibility for conventional defense.

The reduction includes a temporary delay of the deployment of the 2nd Armored Brigade Combat Team, 1st Cavalry Division, which had been slated for a routine nine‑month rotational assignment in Poland and other eastern‑flank positions. Approximately 10,000 U.S. troops are typically stationed in Poland, most on rotational deployments. War Secretary Pete Hegseth met with Polish Deputy Prime Minister and Defense Minister Władysław Kosiniak‑Kamysz to assure that the United States will maintain a strong presence in Poland despite the delay.

Polish officials expressed concern over the postponed rotation but reiterated Poland’s commitment as a "model ally" within NATO. The Pentagon said future deployment decisions will depend on further analysis of U.S. strategic requirements and the ability of allies to contribute to Europe’s defense.
