The USS Milius (DDG-69) is a US Navy Arleigh Burke class destroyer ship that took part in the American counter-offensive in San Francisco in 2027. Over the radio, it can be heard that five Navy destroyers have broken through an enemy blockade in San Diego, and that the Milius and the USS John Paul Jones were en route to assist these vessels in securing the bay..
- The real USS Milius (DDG-69) is a guided missile destroyer based out of San Diego. The Milius received its namesake from Capt. Paul Milius who sacrificed himself to save his crew as his aircraft was going down during the Vietnam War.
- The radio transmission announcing that the John Paul Jones and Milius were in action in the San Diego area is likely an error on the part of the radio operator. San Diego is 500 miles south of San Francisco, too far for the conventional radios in use by the U.S. military during the battle. The usage of a more sophisticated radio or satellite communications system is also ruled out, due to the GKR's EMP attack that would have knocked out North American satellites as well as ground infrastructure. It is possible that the U.S. military worked out new communication lines before the battles.
- The ship's name could be a reference to the game's scriptwriter, John Milius, who also worked on Red Dawn (1984).
