DoD prepares for martial law in CONUS: Marines approved for activation on American soil

"... will come with little warning... in order to respond to threats in the Homeland."

By Shepard Ambellas - October 6, 2019

The Department of Defense issued an order signed by Brigadier General Daniel L. Shipley, Director, Manpower Plans and Policy on October 3, 2019, which authorizes the rapid activation of military forces to protect civil authorities in response to a “major disaster or emergency.”

The order titled Manpower Guidance for Activation and Deactivation of Reserve Component (RC) Marines Ordered to Active Duty ISO Defense Support of Civil Authorities details how Marines will be called to “active duty” upon orders from the U.S. Navy.

Shockingly, one of the first paragraphs details how it “will come with little warning.”

As it states, it's a new version of an old MARADMIN (Marine Administrative Message), actually from 2014:

There is nothing in either one that discusses martial law. It simply is an update to an administrative document regarding the use of the Marine Corps Reserve to assist in a state emergency, like an Earthquake. There's language changes, minor regulation changes, and some clarifications. But nothing really new.

The referenced law (§12304a) is
https://www.law.cornell.edu/uscode/text/10/12304a

(a)Authority.—
When a Governor requests Federal assistance in responding to a major disaster or emergency (as those terms are defined in section 102 of the Robert T. Stafford Disaster Relief and Emergency Assistance Act (42 U.S.C. 5122)), the Secretary of Defense may, without the consent of the member affected, order any unit, and any member not assigned to a unit organized to serve as a unit, of the Army Reserve, Navy Reserve, Marine Corps Reserve, and Air Force Reserve to active duty for a continuous period of not more than 120 days to respond to the Governor’s request.

That's it. Nothing new, and not martial law.
