Peter talks to Professor Jim Storr about the use of simulators in the British military since the 1980s. Why and how they have become such a central element of force development for Western militaries, and what we have failed to extract from their potential use. It seems that simulators have far more potential than we current get from them: and even if we did, they still cannot entirely replace the need for live training events – especially at the combined arms and joint level of exercises. Three people in a room wearing VR headsets really does not make an effective fighting force. Nor one ready for the realities of combat. Industry professionals, it seems, don’t think so either.
