War games: Britain defies Putin with deployment of 900 troops along RUSSIAN border
Units from NATO allied countries take part in the Dragon 15 military exercises
The significant military build up along Poland's frontier with the former Soviet nation is part of a planned Nato training exercise.
Around 900 UK personnel and 350 vehicles - part of the British Army's Lead Armoured Battle Group - crossed Europe to take part in Exercise Dragon 15 on the plains of north east Poland, just 60 miles from the border with the Russian state of Kaliningrad Oblast.
They joined 6,000 Poles, Germans and Canadians on the seven week training exercise, aimed at improving the way the allies worked together.
Britain's war machinery took part in battle scenarios, firing rockets and shells in a simulated attack, with red tracer fire ripping through the air.
