Supporting a Comprehensive All Hazards Response II-9 a. Planning Considerations for Interorganizational Coordination. DOD works closely with other USG departments and agencies, in particular DHS and its subordinate organizations, when planning for DSCA. DSCA plans shall be compatible with the NRF, NIMS, and DOD issuances. DSCA planning should consider C2 options that emphasize unity of effort. DOD organizations and agencies provide numerous LNOs to DHS and DHS components. DOD LNOs may represent organizations and specialties such as the Office of the Secretary of Defense (OSD), combatant commands (CCMDs), combat support agencies, intelligence organizations, or engineers. (1) As the supported geographic combatant commanders (GCCs), Commander, United States Northern Command (CDRUSNORTHCOM), and Commander, United States Indo-Pacific Command (CDRUSINDOPACOM), are DOD’s principal planning agents for DSCA and provide joint planning and execution directives for peacetime assistance rendered by DOD within their assigned areas of responsibility (AORs). In addition to participating in interagency steering groups and councils, DOD has responsibilities under the NRF. (2) DOD coordinates with interagency partners and through the Chief, National Guard Bureau (CNGB), to states/territories on all matters pertaining to the NG to ensure DOD planning supports the needs of those requiring DSCA. Coordination will align with the NRF, NIMS, and interagency coordination guidelines provided in the Guidance for Employment of the Force (GEF) and Chairman of the Joint Chiefs of Staff Instruction (CJCSI) 3110.01, (U) Joint Strategic Campaign Plan (JSCP). (3) The domestic operating environment for DSCA presents unique challenges to the joint force commander (JFC). It is imperative commanders and staffs at all levels understand the relationships, both statutory and operational, among all USG departments and agencies involved in the operation. Moreover, it is equally important to understand DOD’s role in supporting other USG departments and agencies. DOD provides assistance to the primary agency upon request by the appropriate civil authority and upon approval by the President, SecDef, or a SecDef-delegated official (e.g., the supported CCDR). There are also specific USNORTHCOM and USINDOPACOM domestic plans (e.g., DSCA, civil disturbance operations) where the responsibilities of various USG entities are described in detail. b. Elements for Interagency Coordination. The CCMD interagency coordination process complements and supports strategic interagency coordination processes and may involve application of such key elements as joint interagency coordination groups (JIACGs) in campaign plans, operation plans, and concept plans (CONPLANs). Annex V (Interagency Coordination) is found in Chairman of the Joint Chiefs of Staff Manual (CJCSM) 3130.03, Adaptive Planning and Execution (APEX) Formats and Guidelines, and provides a single-source reference to request interagency activities and to lay the groundwork for interagency coordination. All are designed to enhance information sharing, enable effective joint and interagency planning, and maximize coordinated operations.
