Kevlar? Nothing that a .30-06 or .223 won’t penetrate. One day they are really going to piss-off the wrong people.
I have body armor that will stop .30-06 and .223 as do many other law enforcement officers. It’s heavy and cumbersome and only covers the torso but DARPA, Sandia Labs and other organizations are developing body armor that will defeat common rifle calibers, be made of lighter material and cover the entire body. The second amendment is becoming obsolete.
