According to the news organization RT, this is footage from the “Cavalry March” — United States military routing through Romania until they stopped here Thursday, in Brasov. They (400 U.S. Army soldiers with 80 Stryker armored personnel carriers of the 2nd Squadron, 2nd Cavalry Regiment) eventually came to rest at Cincu military base.

The move signals the start of multinational NATO war games in the Eastern European nation, which borders Ukraine — a country on the verge of conflict with Vladimir Putin’s Russia.
