Achieving an Integrated Force
Update on multi-domain integration and multi-domain operations
The UK has updated its position on multi-domain integration to align with NATO terminology and doctrine. References to multi-domain integration (MDI) on this page reflect the language in use at the time of publication. The UK now uses the term multi-domain operations (MDO) in line with NATO allies.
Multi-Domain Integration (MDI) is about ensuring that every part of defence can work seamlessly together, and with other government departments and the UK’s allies, to deliver a desired outcome.
The modern battlespace is more complex than ever before, and the nature of the threats we face means that no single service, no single government department, or no single nation can tackle them on their own.
Multi-Domain Integration is the UK response. It is a mindset, and requires substantial changes across defence and wider-government. MDI will not happen by accident, and Strategic Command as defence’s integrator is responsible for implementing this change.
