UK Defence Medical Services' support to the development of a multiagency major incident plan in South Sudan.

UK Defence Medical Services personnel deployed in support of the United Nations Mission in South Sudan as part of Operation TRENTON in 2017-2018. 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. Major incident management is one of several technical areas ripe for a proactive Defence Healthcare Engagement strategy, seeking to offer capacity building in areas where Defence is rich in expertise that is highly sought after by other sectors.
