The National Cyber Range (NCR), an arena for developing the next generation of cyberwar weapons and tactics, has been funded by DARPA.

Computer programs acting like real people will populate a virtual world that cyberwarriors will attempt to disrupt or save, depending on the mission.

DARPA hopes that the NCR will be able to simulate the entire Internet, allowing soldiers to drill in virtual simulations ranging from a small scale computer virus to a World War III-sized conflict.
