NATO's commander for Europe says the U.S. and other NATO members are considering placing military equipment in the alliance's eastern flank nations.

Gen. Philip Breedlove spoke Tuesday during the large BALTOPS 2015 sea exercises in Poland that are part of the alliance's maneuvers this month intended to reassure the eastern flank nations, which are concerned about Russia's resurgence.

Breedlove said the possibility of "prepositioning" heavy army equipment was discussed at the NATO summit last year and that now "many nations consider this."

He said the U.S. is "clearly" considering it, although the decisions and announcements haven't been made yet.

Poland said Sunday it is in talks over hosting U.S. equipment and is expecting a decision "soon."
