U.S. military forces have deployed one of the nation’s most elite groups of airborne division soldiers to Europe for the first time since World War II, vowing to fight alongside Ukrainian troops in the war against Russia, according to a report.

CBS News reported Friday that the U.S. Army’s 101st Airborne Division, a group trained to deploy anywhere in the world and fight within hours, deployed approximately 4,700 soldiers from Fort Campbell, Kentucky, to Romania, where soldiers stand ready to reinforce NATO’s eastern flank on a moment’s notice.
