This has been discussed on some other threads over the past few days. From what I and some other vets read from it, it’s a standard being reissued.
If you really wanted to see if it changed anything you’d have to pull the predecessor which was MARADMIN 300/14.
I think the main reason it’s getting discussion is the press and others highlighting and stirring the pot on remarks made about impeachment, civil war, etc over the past 2 weeks.
Thanks for your input. Was thinking this kind of thing needed its own thread to put together info from freezers.

It is nothing new, just some administrative adjustments. Each service has this guidance (plus doctrine and other documents) to govern how they conduct “Defense Support to Civil Authorities.” This is DoD speak for helping out civilian authorities during an emergency/disaster.
The messages get reviewed, updated, and reissued every few years, even if there are no substantive changes.
