The Joint Chemical, Biological, Radiological and Nuclear Defence Centre of Excellence (JCBRN Defence COE) is the centre of gravity for CBRN defence-related expertise, experience, and transformation within the Alliance. The Centre combines the skills and expertise of over 70 personnel from fourteen nations. We focus on concept development, doctrine and standardization, lessons learned, capabilities development, and defence planning. We serve as the Department Head for NATO’s WMD/CBRN defence training and education discipline and offer a wide portfolio of certified courses. The Centre forms the core of the NATO CBRN reachback capability providing timely, coordinated, authoritative, and detailed technical and scientific support to SHAPE.
