US Air Force General Philip Breedlove said NATO needs to consider having a long-term troop presence deployed in the region "for as long as required" to address the Russian threat.
Breedlove's comments came at a meeting today of NATO defense ministers, following President Barack Obama's announcement that the US will boost its military presence in Europe in response to Russia's annexation of Ukraine's Crimean region. Obama has said he will ask Congress to provide up to USD 1 billion to fund the effort.
US officials have said they believe roughly seven battalions of Russian troops remain, but that number may be smaller now. Breedlove would not provide an estimate.
Speaking to reporters today, Breedlove said NATO needs "to have a much more responsive force to address this new threat that we see."
He said the allies will consider where the force should be positioned and whether it should move in and out on a rotational basis or remain in the region as long as needed. He said he has recommended that NATO consider prepositioning military equipment in the region, but no final decisions have been made yet.
