The open area of this website introduces interested parties to the role and history of Defence Intelligence and its predecessors. Current and former staff are entitled to join Dissociation where academic, historic and pertinent individual contributions can be accessed. The members’ area gives details of the full range of our activities and access to the growing library of contributions on historical and professional topics. Both areas are dynamic and, in keeping with the tradition of Defence Intelligence, populated with material that informs and challenges established perceptions.
