John pleads with the General to delay the offensive defense, but Ashdown refuses and relieves John of his command. However, the Resistance forces disobey Ashdown's orders and, instead, await John's signal. Marcus enters the base, interfaces with the computer, and disables perimeter defenses so that John can infiltrate the cellblock and release human prisoners. Marcus learns from Skynet (which assumes the form of Dr. Kogan on a screen) that he was created and built to lure John to this base; when the Resistance launches its attack, John will be killed, achieving the goal that Skynet had failed to accomplish so many times before. The radio signal that the Resistance received is revealed to have been a ruse, and Skynet uses it, to track down and destroy the command submarine with the Resistance's leaders aboard.
