Future Soldier (British Army)

Future Soldier is a reform of the British Army resulting from the Integrated Review of Security, Defence, Development and Foreign Policy ("Global Britain in a Competitive Age") published in March 2021. The aim of the reform is to create a more lethal, agile and expeditionary force, able to fight and win wars and to operate in the grey-zone between peace and war. Future Soldier was published on 25 November 2021 and deals with the organizational changes of the British Army, with changes to personnel and equipment were set out in the Defence in a Competitive Age paper published on 22 March 2021.
