About 8,000 British army troops will take part in exercises across eastern Europe to combat Russian aggression in one of the largest deployments since the cold war. Dozens of tanks will be deployed to countries ranging from Finland to North Macedonia this summer under plans that have been enhanced since Russia invaded Ukraine. Joining them will be tens of thousands of troops from Nato and the Joint Expeditionary Force alliance, which includes Finland and Sweden. The Ministry of Defence said the action had been long planned and had been enhanced in response to Russia’s invasion of its neighbour in late February. Commander Field Army Lt Gen Ralph Wooddisse said: “The UK makes a significant contribution to the defence of Europe and the deterrence of Russian aggression. “The British army’s series of exercises is fundamental to both. “The scale of the deployment, coupled with the professionalism, training and agility of the British army, will deter aggression at a scale not seen in Europe this century.” The UK deployment is expected to build to a peak of about 8,000 personnel operating in mainland Europe between April and June. The defence secretary, Ben Wallace, said: “The security of Europe has never been more important. These exercises will see our troops join forces with allies and partners across Nato and the Joint Expeditionary Force in a show of solidarity and strength in one of the largest shared deployments since the cold war.” Troops from the Queen’s Royal Hussars have been deployed and will be embedded in an armoured brigade in Finland, which shares an 830-mile land border with Russia. Exercises alongside American troops are also taking place in Poland.
