Polish Defence Minister Mariusz Błaszczak on Monday watched as soldiers trained together to respond to potential adversaries along the narrow, 100-kilometre-long corridor, known as the Suwałki Gap.
The Bull Run 12 multinational rapid response exercise near the northeastern Polish towns of Olecko and Augustów by soldiers from NATO's Enhanced Forward Presence Battle Group Poland aims to test interoperability and an ability to efficiently move troops and military hardware.
The Suwałki Gap is nestled between northeastern Poland and southern Lithuania. It is flanked on either side by Belarus and Russia's Baltic Sea exclave of Kaliningrad.
Poland and Lithuania, both members of NATO, last year agreed to assign a brigade of troops to reinforce the Suwałki Gap amid reports of growing Russian military build-up in the Kaliningrad region.
