I saw a show a while back where they were demonstrating the US Army's 50 cal sniper rifle. It was punching a hole through half inch armor plate at something like 500 yds. I also seem to recall they have an "armor piercing" round for the 50 cal machine gun. Hard to believe they could come up with body armor that could stop that - at least body armor that anyone would be able to wear and still move...
Maybe the Russians are re-defining body armor as a small one person tank
