Twenty thousand British soldiers, sailors and aviators will be deployed by land, sea and air across Europe to participate in a huge Nato exercise later this year. The UK is expected to send 20,000 military personnel to take part in Exercise Steadfast Defender 24 – one of Nato’s largest military exercises in Europe since the Cold War. During the first half of 2024, personnel from the Royal Navy, the British Army, and the Royal Air Force will deploy across Europe alongside 31 Nato allies and Sweden as the alliance practises repelling an invasion by Russian forces.
