An Army infantry brigade from Fort Johnson, La., will deploy to Europe in summer to train alongside NATO forces in a regular troop rotation, the service announced Wednesday.

The 10th Mountain Division’s 3rd Infantry Brigade Combat Team will deploy to Eastern Europe to replace soldiers from the 101st Airborne Division’s 3rd Infantry Brigade Combat Team, Army officials said.

The deployment will come on the heels of another exercise in Europe in which Fort Johnson soldiers are now participating. Hundreds of 3rd Brigade, 10th Mountain soldiers deployed to northern Europe in recent weeks to train in an exercise known as Immediate Response 24, which will see the soldiers operate across Norway and Finland through the end of May, according to the Defense Department.

The later deployment will support the ongoing Operation Atlantic Resolve, which the United States launched in 2014 after Russia’s initial invasion of Ukraine when it annexed the Crimean Peninsula. The operation — meant to bolster NATO’s eastern flank and dissuade Russian forces from entering the alliance’s territory — grew larger after Russia’s 2022 full-scale invasion of Ukraine.

Since deploying to Eastern Europe in November, roughly 3,400 soldiers of the 3rd Brigade, 101st Airborne have operated in multiple NATO countries, including Estonia, Poland and Romania, photos on the unit’s social media pages show. The brigade will return to its home station at Fort Campbell, Ky.

While the rest of the 10th Mountain Division is based at Fort Drum, N.Y., the division’s 3rd Brigade is based at Fort Johnson, where it regularly trains at the Army’s Joint Readiness Training Center.
