Department of Defense Dual-Status Commander D-9 (4) DSC Orientation Course, (5) State orientation visits (NG JFHQ-State, state EOC), and (6) Interview with the Deputy Director of the Domestic Operations Directorate within the Operations Directorate at USNORTHCOM. c. NG deputy commanders, if appointed by the state(s), will be offered the same training opportunities as the designated DSC and Title 10, USC, deputy commander. The NG deputy commander, if appointed, will be employed IAW state direction. 9. Appointment Process When it is anticipated that a DSC will be necessary and proper, coordination will immediately commence between key military leaders (TAG, CNGB, GCC, Joint Staff, and OSD), on behalf of their principal (governor or SecDef). For requests initiated from the affected state, TAG will notify the CNGB and CCDR of the state’s desire to seek appointment of its nominated DSC. The CNGB and CCDR will coordinate with the CJCS and ASD(HD&GS) to verify the qualification and certification of the nominee and provide SecDef a recommendation on the appointment of the DSC. ASD(HD&GS) will determine whether a signed MOA exists between the state and DOD or if there is a need to establish one for this specific event or incident and prepare it for signature by the principals. Additionally, ASD(HD&GS) will ensure the pre-coordinated DOD appointment memorandum is ready for SecDef’s signature, and NGB will ensure the state has the state appointment memorandum ready for the governor’s signature. When time does not permit, a conference call will be arranged between the governor and SecDef to discuss the appointment of a DSC and with the governor’s consent and SecDef’s authorization, the MOA will be verbally executed based on oral agreement with signatures of the appointment memorandums to be obtained as soon as possible. Upon SecDef’s authorization, the CJCS will communicate the decision, via order or memorandum, to the supported commander and supporting commanders. a. For requests initiated from DOD, a similar process will occur, but the request will be initiated by CDRUSNORTHCOM, with SecDef’s consent. b. For requests that occur during principal level discussions (governor and President/SecDef), which key military leaders (SecDef, CJCS, CNGB, CDRUSNORTHCOM, TAG) are unaware, it is imperative that the immediate dissemination and coordination occur to inform all parties of the oral agreement and ensure that signatures are obtained as soon as possible. (A governor may request approval via SecDef verbal authority in an emergency situation.) 10. District of Columbia a. The District of Columbia, a federal district, is unique. Although the District of Columbia has an NG, the District of Columbia has no governor. Instead, the District of Columbia NG reports to the President of the United States.
