The wars in Iraq and Afghanistan required that forensic science was used beyond the traditional law enforcement and criminal justice goals and applied to military operations. The 9/11 terror attacks in the United States (US) inspired further attacks in the Western World and highlighted the importance of national and international intelligence sharing for counterterrorism operations. Following the 9/11 attacks, anthrax was disseminated in the US mail system, demonstrating a successful modern use of biological agents. As a result, nations enhanced their Chemical, Biological, Radiological and Nuclear (CBRN) capabilities to prevent, prepare, respond, and recover from CBRN attacks but in the last decade, there has been a decrease in capabilities across military forensic science, counterterrorism, and CBRN. Recent changes in the global and strategic environment such as, the war in the Ukraine, the threat of grey zone conflicts (below the threshold of war) such as the conflict in the Middle East, and strategic competition, indicates international, national, state and local CBRN capabilities need to be reinvigorated in a world under digital transformations. There is a need for a harmonized approach to enhance the integration of military, law enforcement, and CBRN operations to support decision-making. In this paper, we look back to where we have come from and where we are now to make recommendations on where to from here for military forensic science and counterterrorism, including CBRN which intersects both of these systems.
