The US military is also helping train Ukrainian armed forces.
In November, approximately 150 members of the Florida National Guard’s Task Force Gator were deployed to Ukraine as part of the Joint Multinational Training Group-Ukraine, replacing the Washington National Guard. Established in 2015, the training group aimed to improve Ukraine’s defense capabilities.
In addition to Task Force Gator, Special Operations Command Europe has a “major role” in training and advising Ukrainian special forces through exercises, communication and coordination “at every level,” the Pentagon said in a statement on Tuesday.
For security reasons, the Pentagon did not disclose how many special forces were in Ukraine.
“Training with our Ukrainian partners cultivates trust, strengthens readiness and develops relationships, which in turn promotes peace and stability across Europe,” Pentagon spokesman Lt. Col. Anton Semelroth said in the statement.
The Pentagon would not comment on the schedules for training, operations, or deployments, nor would it say whether any schedules have changed in light of the build-up of Russian forces near Ukraine.
Marines from Europe and the region are operating across the continent for training and exercises, the Pentagon said, and thousands of Marines from the II Marine Expeditionary Force will be participating in the biannual cold response exercise in Norway next year.
The US Army Europe and Africa trains in Poland, Lithuania, Romania, Germany, the Netherlands and Greece.
The Florida National Guard’s 164th Air Defense Artillery Brigade is based in Ansbach, Germany.
