The near-permanent deployment of a NATO battalion under US command marks the first time NATO troops have been placed so close to Russian territory, a step that Kremlin denounces as a threat to its own security.
But Polish President Andrzej Duda described the deployment for Poles as a symbol of liberation and inclusion into the Western democratic world. At a ceremony in Orzysz, Duda said: "it's not an exaggeration to say that generations of Poles have waited for this moment since the end of the Second World War."
