I found a link that describes it. Apparently it isn't quite as tough as the Abram's armor, but it is vastly lighter and can withstand considerable punishment. Sounds like a perfect armor for this new Stryker vehicle I keep hearing about.

Yeah, but remember, you can add fairly lightweight "reactive armor" if you really need it, and dramatically increase the survivability. The Brits never used reactive because of the Chobham, and we apparently never thought we needed it. But the Russkies did.
