The storming of the Capitol bears all the signs of a skilled military operation, experts now say. Finding out where the insurrectionists got their training is "a tier one priority" of investigators, who have identified at least twenty-one US Military veterans as having participated in the riot and siege of the Capitol. Men in combat gear were captured on camera using a tactic known as ranger file to push through the crowd and make their way into the Capitol. Many rioters wore flak jackets and helmets.
