Pentagon Launches Salvo in War to Protect an Army of 7 Million

War is coming -- a war of ones and zeroes, that is.

The Pentagon has unveiled a Cyber Command center, designed to shield the military's 15,000 networks and more than 7 million computers from foreign hacker attacks, that will pool resources from a variety of military intelligence agencies to proactively prevent assaults.

It's a pre-emptive, all-out attack on the more than 100 foreign intelligence agencies working to penetrate American computer systems and steal U.S. weapons technology.
