Supporting a Comprehensive All Hazards Response II-11 For further reference, see JP 3-08, Interorganizational Cooperation, and the NRF. 7. Unity of Effort The diplomatic, informational, military, and economic power of the US are applied in unified action to attain desired end states. a. Responsibilities. Incidents are managed at the lowest level possible. Federal support is provided in response to requests from state or local officials through the state coordinating officer to the federal coordinating officer. The federal coordinating officer coordinates for DOD support through the defense coordinating officer (DCO) in the JFO. DOD may provide support to the LFA, which has the lead in managing the federal response to a domestic incident. DHS is responsible for domestic incident management and the framework for federal interaction with state, local, territorial, and tribal governments; the private sector; and NGOs in the context of incident preparedness, response, and recovery activities. DOD support to this response will be initiated through a formal RFA or mission assignment process or provided as directed by the President or SecDef. The integrity and Federal Emergency Management Agency, the National Guard Bureau, the individual states, and US Northern Command resulted in a swift and coordinated response, to include prepositioned Title 10, US Code, resources in the region along with the immediate response of National Guard, state, and local resources. US Transportation Command and interagency partners executed strategic and ground movements of Department of Defense (DOD) assets and thousands of short tons of equipment, to include private/commercial power utility company trucks and personnel. The DSCs provided critical leadership to achieve greater unity of effort between federal and state military forces in preparing for and responding to the devastating effects of this hurricane. The federal government learned the importance of anticipation during Hurricane Sandy. 2017 brought even greater challenges, as DOD responded to an unusually high number of disasters. These included a trio of category 4 and 5 hurricanes (Harvey, Irma, and Maria) and wildland fires, as well as an earthquake in Mexico. The disasters of 2017 resulted in a thorough after action review process to ensure DOD capabilities are used most efficiently in complex disasters. Initial themes are focused on enabling common pictures across all levels of government for requesting, tasking, and understanding the execution of DOD capabilities throughout the disaster response. It is apparent the DOD recognition of DSCA as a key mission has resulted in the improved planning, training, exercising, and anticipation of key capabilities. A common thread throughout DSCA operations is the importance of partnerships and professional relationships that enable enhanced unity of effort for the accomplishment of DSCA missions.
