‘Grey Zone Warfare’ has emerged since 2014 as one of the key strategic challenges of the 21st century. The ‘Grey Zone’ lies between peaceful (white) action carried out by a nation and hostile (black) action, which could be seen as an act of war. Hence it can be a nebulous concept. Yet the threat is real. NATO has identified ‘growing global uncertainty, more sophisticated and disruptive cyber and hybrid threats, and exponential technological change’ as significant dangers.
We aim to provide clarity by characterising ‘Grey Zone Warfare’ in order to develop understanding of the present and most likely future of warfare. To do this, we have developed a network to study ‘Grey Zone Warfare’, to classify it and develop case studies. Our audience includes academics, practitioners and policymakers, the media, NGOs, and the public. Our work will help make sense of Grey Zone Warfare and put it into perspective.
