The Unified Coordination Group?

The Unified Coordination Group (UCG) provides coordination leadership at the Joint Field Office (JFO).

The UCG is a structured group responsible for managing disaster response operations at the field level. It operates from the JFO, applying unified command principles to align federal, state, tribal, and local efforts during emergencies. Comprised of senior leaders from various sectors, the UCG ensures that assistance is effectively coordinated to address diverse needs and challenges during disaster response.
