This guidance is designed to assist you, as Defence personnel working at the operational and tactical levels, to integrate effectively with Partners across government (hereafter 'Partners') to achieve the UK's objectives. The guidance reflects an increased emphasis in Her Majesty's Government (HMG) on integration. It follows the Integrated Review 2021 and the Integrated Operating Concept, and contributes to emerging doctrine from the Ministry of Defence (MOD) on Integrated Action. The guidance has its foundation in the UK's Fusion Doctrine. It is the product of research within UK Defence and has drawn on expertise from across the MOD, HMG and wider industry. This guidance is intended to complement military doctrine - it is not doctrine itself. Rather than being a step-by-step guide for integrating with Partners, it is intended as a useful reference that you can reach for when working alongside Partners. It also offers a way of operationalising strategic guidance for integrating with Partners. It focuses on planning and delivery of national security activities overseas, and sub-threshold activities where Defence may be supporting different partners. However, the guidance may be useful for other areas, including UK-based activities, and for Partners who work with Defence.
