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 be stationed at military bases in Alabama and Arizona, with purview of regions east and west of the Mississippi River, respectively. Cost projections outlined in the documents indicate that such a mission, if the proposal is adopted, could stretch into the hundreds of millions of dollars. Trump has summoned the military for domestic purposes like few of his predecessors have. He did so most recently Monday, authorizing the mobilization of 800 D.C. National Guard troops to bolster enhanced law enforcement activity in Washington. The proposal represents a major departure in how the National Guard traditionally has been used, said Lindsay P. Cohn, an associate professor of national security affairs at the U.S. Naval War College. While it is not unusual for National Guard units to be deployed for domestic emergencies within their states, including for civil disturbances, this "is really strange because essentially nothing is happening," she said.
