UN Department of Operational Support

The UN Department of Operational Support (DOS) is responsible for providing administrative and logistical assistance to UN peacekeeping and special political missions worldwide. It ensures these missions have the necessary resources—such as transportation, communications, supplies, and security—to operate effectively. DOS also manages infrastructure, human resources, and financial support, enabling field missions to carry out their mandated tasks. Essentially, it acts as the backbone of UN operations, making sure teams in challenging environments can function smoothly and safely to promote peace and stability.
