Hybrid Warfare is not a new phenomenon, but the use of the term is recent, and the concept came to the attention of European scholars, experts and policy makers with the start of the conflict in Crimea. At the high end of the spectrum of hybrid warfare tools is the military force. Hence, one rightfully expects to see commensurate military measures, reflected in national and allied defence policies. This chapter therefore takes a look first at the types of military capabilities and level of readiness necessary to counter hybrid warfare. It emphasizes the requirements for relatively light, highly maneuverable forces, capable to operate in urban environment and work with local communities, along with a capacity to achieve and maintain information and knowledge superiority and to repel an assault from the air or the sea. Then it calls for enhanced cooperation, coordination, and collaboration (C3) among multiple stakeholders that cover a spectrum well beyond the traditional remits of the security sector. Towards the provision of adequate capabilities and effective C3, the author emphasizes organizational agility and adaptiveness. The final section discusses the need to strengthen the integrity of defence organizations, thus limiting opponents' opportunities to influence the behavior of decision-makers and other defence personnel.
