From the Washington Examiner:
U.S. ground troops are creating a defensive line against further Russian advances that stretches from the Baltics to the Black Sea, the brigade commander in charge of the U.S. forces assisting Ukraine said Monday.
The U.S. support of its NATO allies in Europe, known as Operation Atlantic Resolve, has grown into two distinct mission sets — Atlantic Resolve North, supporting Poland and the Baltic states of Latvia, Lithuania and Estonia; and Atlantic Resolve South, the countries of Hungary, Georgia, and the Czech Republic.Each will have U.S. troops deployed there.
The 173rd is also sending six company-sized elements, and three battalion headquarters sized elements into Ukraine to begin its defensive training for Ukrainian forces that are still under attack by Russian-backed forces in eastern Ukraine. A company is typically anywhere from 60 to 250 personnel.
"We're expanding. "Stretched from the Baltics all the way to the BlackSea, you will see a line of deployed U.S. troops," Col. Michael L. Foster, commander of the U.S. Army's 173rd Airborne Brigade, said.
