One key contribution was the development of a multiagency major incident plan in collaboration with key stakeholders within the region, including our UN partners, other troop-contributing countries and non-governmental organisations. This paper describes the process and contribution made, with some transferable lessons for future similar operations, such as adaptation of our courses.
