The exercises, backed by aircraft, tanks, artillery and armored assault vehicles, will take place in Finland, Poland, North Macedonia and along the Estonian-Latvian border. They will include troops from Nato and the Joint Expeditionary Force, which includes non-Nato members Finland and Sweden.
“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,” Lt. Gen. Ralph Wooddisse, commander of the U.K.’s field army, said in a statement.
The deployments will begin this week in Finland, where troops from the U.S., Britain, Estonia and Latvia will participate in Exercise Arrow to improve their ability to work alongside Finnish forces.
Also this week, some 4,500 troops will take part in Exercise Swift Response, which will include parachute drops and helicopter-borne assaults in North Macedonia. The operation will include forces from U.S., Britain, Albania, France and Italy.
Next month, 18,000 Nato troops, including forces from Britain, France and Denmark, will take part in Exercise Hedgehog along the Estonia-Latvia border.
In late May, about 1,000 British soldiers will join troops from 11 other nations for Exercise Defender in Poland.
“The security of Europe has never been more important,” UK Defense Secretary Ben Wallace said. “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.”
