As the military transitions into a tech-heavy force, increasingly reliant on robots and drones, local police forces are looking less like law enforcement and more like heavily armored combat units. Now, it seems they are starting to train like them, as well.

A story published by The State newspaper in Columbia, South Carolina, reported on recent secret joint training missions between U.S. Army special forces and the Richland County (South Carolina) Sheriff’s Department.

The article describes training exercises being conducted by “unidentified units” from Ft. Bragg, North Carolina. Ft. Bragg is the home of the elite U.S. Army Special Operations Command (USASOC) and the super-secret, super-deadly Delta Force.
