By June 2021, North Carolina residents had National Guard soldiers in full uniform show up at their homes. To my knowledge, Smithfield, North Carolina, is the first region within the United States to perform such measures. You can see video proof here.
Josie Hines was one of many Americans faced with such measures. She had a health official with a clipboard show up at her front door. And guess who was standing behind that health official—three uniformed National Guard soldiers.
