The U.S. Army has called off the planned deployment of the 2nd Armored Brigade Combat Team, 1st Cavalry Division — a force of more than 4,000 troops along with its equipment — to Poland.

An Army representative confirmed the cancellation on Wednesday but did not provide further explanation, directing all inquiries to the Defense Department, which has yet to respond.

During Tuesday’s congressional hearing focused on the Army’s budget outlook, neither Army Secretary Dan Driscoll nor Vice Chief of Staff Gen. Christopher LaNeve addressed the canceled deployment. However, news of the decision had already begun circulating among service members earlier that day, as soldiers informed family and friends through text messages.

At the hearing, Sen. Jack Reed of Rhode Island, the senior Democrat on the Senate Armed Services Committee, stated that the Army is dealing with a funding gap of at least $2 billion. He attributed the strain to prolonged missions, including National Guard deployments in Washington, D.C., and troop assignments supporting U.S. border operations.

Reed questioned how these financial pressures might affect military readiness and training, though the issue was not discussed further during the session.

A report from ABC News suggested the deficit may be even larger than Reed estimated. According to Army officials cited in the report, the actual shortfall could range from $4 billion to $6 billion.

In April, the Pentagon announced plans to remove around 5,000 troops from Germany. Defense Department spokesperson Sean Parnell explained that Defense Secretary Pete Hegseth approved the reduction after evaluating operational requirements and current regional conditions.

The reduction would return the U.S. military presence in Europe to levels seen before Russia’s 2022 invasion of Ukraine, a conflict that has resulted in the deaths of more than 43,000 Ukrainian soldiers and at least 100,000 Russian troops, according to the U.K.-based monitoring organization Every Casualty Counts.

Currently, over 10,000 American troops rotate through Poland. The “Black Jack” brigade had been scheduled for a nine-month deployment, and according to Stars and Stripes, the Fort Hood-based armored unit held a casing-of-the-colors ceremony on May 1 in preparation.

Under the original deployment schedule, advance elements of the brigade had already arrived in Poland, while equipment shipments were reportedly en route.

Officials at Fort Hood and Army Headquarters redirected all questions to the Defense Department, which declined to provide additional details.

“We have no comment on this at this time,” the Pentagon press office stated in an email to Army Times.
