Achieving an Integrated Force
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.
