Chapter II - Domestic CBRN CM (4) Considerations: (E) CBRN Response Operations: (4) Phase III: Dominate (Operate): In phase III, planning and execution efforts are synchronized and integrated with the efforts of the supported civil authorities, as well as other military operations that may be occurring simultaneously (e.g., technical nuclear forensics sample collection) within the same operational area. Phase III begins when DOD and/or NG forces begin executing mission assignments within the operational area. The coordinating agency typically assigns mission assignments to supporting or cooperating agencies for action. DOD accepts mission assignments as RFAs, which become mission assignments only after being received through the Office of the Executive Secretary of DOD, forwarded to the ASD(HD&ASA) and the JDOMS for validation and order processing, and then approved by SecDef. Once SecDef approves the request, an order is issued to combatant commands, Services, and/or agencies to accomplish the mission. In the case of the DCRF and C2CRE, SecDef has authorized CDRUSNORTHCOM to approve the mission assignments as long as they are within the scope and capabilities of the DCRF and C2CRE. During this phase, the primary focus is on mission assignments that involve incident site lifesaving and injury prevention. Key tasks during this phase are hazard assessment, casualty search and extraction/rescue, ambulatory and non-ambulatory decontamination, emergency medical services, air and ground medical/casualty evacuation, and logistical support. (a) The CJTF exercises OPCON over all designated DOD forces as directed by the CCDRs EXORD. The commander of a JTF-State exercises OPCON over all designated NG forces as directed by the approved EXORD or EMAC agreement. The JTF may task organize functionally, by Service components, or a combination of both, depending on the situation. The JTF is responsible for executing mission assignments using the allocated DOD forces within the designated operational area. The JTF-State is also responsible for executing mission assignments using NG forces within the designated operational area and requesting additional forces from the supported CCDR if those within the designated operational area are not adequate. The JTF receives mission assignments from the DCO/DCE after they have been validated. The JTF maintains force readiness and sustainment requirements for assigned forces in the designated operational area. (b) The CJTF begins to assign missions to the JTF component commanders, who in turn task their units as they become available within the JOA. In some cases, mission assignments will be awaiting specialized units as they arrive. Each TF can expect to receive multiple missions together with a priority of effort. Commanders should conduct information engagement actions with residents and responders working near their forces. (c) Certain units may work closely with highly specialized personnel from other agencies as part of their mission assignment. The TF commander may be required to support these agencies and should coordinate with them to assess the progress of operations. (d) Normally Joint tactics, techniques, and procedures and mission essential task list conditions and standards derived from the Universal Joint Task List (UJTL) are adequate to meet the tactical expectation of civil authorities; however, in some circumstances, additional requirements may be established. Joint forces should expect some local authority coordination and periodic work oversight to confirm that projects are progressing on time and confirm that performance is to acceptable civil standards. Phase III ends when deployed Title 10, USC, Title 32, USC, and/or state active duty NG forces have completed the preponderance of incident site lifesaving mission assignments and the effort shifts to other state and/or federal mission assignments that have broader application to the JOA
