The Trump administration is evaluating plans that would establish a “Domestic Civil Disturbance Quick Reaction Force” composed of hundreds of National Guard troops tasked with rapidly deploying into American cities facing protests or other unrest, according to internal Pentagon documents reviewed by The Washington Post.

The plan calls for 600 troops to be on standby at all times so they can deploy in as little as one hour, the documents say. They would be split into two groups of 300 and stationed at military bases in Alabama and Arizona, with purview of regions east and west of the Mississippi River, respectively.
