NATO began the Rapid Trident exercise in the Ukrainian city of Lviv located near the Polish-Ukrainian border. Forces participating in this years exercise number about 1300 from 15 NATO member and former East Bloc nations. The organization has held war games in Ukraine in the past, and NATO was quick to point out that the exercise was planned well in advance of the recent political turmoil in the east near the Russian border.
