There is a new armor technology that just recently received NIJ certification. It is based on proprietary process of alloying aluminum with carbon nanotubes. The product is far superior to any thing on the market. It stops EVERY thing. The army did some tests with the plates - from 9mm to 50 cal to C4 in pipe bombs. I will try to get the links up. If I fail, then PLEASE, someone with HTML skills, help me.

I’ve seen a helmet made with this stuff and it had been shot with a .50cal and there was barely a dent! I saw another plate that had been hit with 60 rounds (not sure of the caliber) with no penetration. Totally amazing. I think that once it gets traction, a lot of companies will go out of business. Hence, there might be a lot of resistance too.
Cool vids
THAT is impressive!
