6,000 NATO troops hold one of largest post-Cold War drills near Russia's borders.

Poland and the Baltic states are hosting the largest strategic war games the defense alliance has held in ten years. The NATO Response Force will practice defending the Baltics from an unidentified foreign invader.
The ‘Steadfast Jazz’ exercise, launching on Saturday, gathers some 6,000 troops from all NATO members as well as non-member states - Finland, Sweden and Ukraine. Around half of them will participate in live exercise training, which will involve dozens of armor, aircraft and naval vehicles. The other half of the personnel are headquarters staff, who will take part in command and control drills.
