As of early 2022, the U.S. Defense Department activated around 20,000 troops in Europe to support NATO in response to Russia’s invasion of Ukraine. As we enter 2024, these troops remain on rotating deployments as part of the ongoing mission. The deployed personnel include those from brigade combat teams stationed in Romania and Poland, and there are plans to increase the Navy’s presence in Rota, Spain. Despite the absence of a separate named operation, the increased rotations have become part of Operation Atlantic Resolve, which has been ongoing since Russia’s annexation of Crimea in 2014. The U.S. has also established a long-term assistance command in Germany to coordinate training rotations with Ukrainian troops. Army Maj. Charlie Dietz stated that there are currently no plans to reduce the forces deployed, as the security situation remains a concern.
