The Integrated Review is an opportunity for the Ministry of Defence to explain how our Armed Forces will fight in the future. It is promising that work is underway to develop new operating concepts but it is vitally important that this work is communicated to wider Government stakeholders involved in the Review before its completion. As demonstrated by COVID-19, our Armed Forces are required to fulfil a diverse range of domestic and international tasks. Their concept of operations must realistically reflect what commitments are possible with the resources and capabilities available. These concepts should inform capability and funding decisions made as part of the Review and, given their significance, one key output of the Review should be to formally record these new operating concepts in doctrine.
