ORDER TO ACTIVE DUTY TO PROVIDE ASSISTANCE IN RESPONSE TO A MAJOR DISASTER OR EMERGENCY.
TOTAL FORCE MOBILIZATION, ACTIVATION, INTEGRATION, AND DEACTIVATION PLAN (MAID-P).
In accordance with (IAW) REF A, this MARADMIN provides guidance for the activation of Reserve Component (RC) Marines under §12304a, Title 10, U.S. Code, following a request for Federal assistance in response to a major disaster or emergency within the United States. Requests for Federal assistance will come with little warning. As required, the Marine Corps must rapidly mobilize RC units and personnel IAW this MARADMIN in order to respond to threats in the Homeland.
This order specifically references the President of the United States as the commanding officer:
SECNAV’s delegated authority may be exercised only after: (Note: SECNAV means Secretary of the Navy)
…2.B.2. When directed by the President in support of (ISO) a request for assistance (RFA) from a primary Federal department or agency…
This order also invokes the “Marine Emergency Preparedness Liaison Officer (EPLO)” as well as a large contingent of U.S. Marines forces:
USNORTHCOM and USINDOPACOM requests EPLO activation through its USMC service component, Marine Forces North (MARFORNORTH) and Marine Forces Pacific (MARFORPAC).
COMMARFORNORTH/COMMARFORPAC should consider using on hand Active Component (AC) and Active Reserve (AR) personnel to meet immediate IA requirements.
The order also appears to underscore something called, “involuntary activation authority” as explained here:
RC personnel can be sourced from the Individual Ready Reserve (IRR) or Individual Mobilization Augmentee (IMA) program with the involuntary activation authority residing with SECNAV and SECDEF.
4.C.3. Ensure coordination is conducted with MARFORPAC and MARFORNORTH regarding the expected or planned RC IA mobilizations either in a voluntary or involuntary status.
4.C.6. As required, act on delegated SECNAV authorities for volunteer mobilization orders under §12301(d) for the initial 72 hour Immediate Response Authority period IOT facilitate a rapid time-sensitive response.
