You're correct, I misspoke when comparing the two types of body armor. The old RBA which I use to wear could not stop a 7.62 round. The new Interceptor body armor can stop one 7.62 round from 50 meters. The problem they're going to run into is the insurgents will upgrade to a stronger round. (ex armor piercing, smart ammunition) I wish I could find the video. There is a video where they put level IV body armor on live animals. What they did was try out different ammo to see what got through it. Not exactly endorsed by PETA, but it got the point across.
