The alien Chasta put their war machine into gear and humankind was suddenlyin the worst fight it had ever known - and lost. The solar system will beannexed by the Chasta within the next thirty days. If humankind can't be theU.S. Army anymore, then it will have to be the Viet Cong. Disgraced Captain John Ryder gets a ship and crew and leads them into spaceas guerrilla fighters. Once clear of the system, they locate a place to hidebetween sorties and begin fighting. They strike from behind and shoot fromcover. If they can't give them hell, Ryder and crew at least give them a hardtime. The Chasta throw a ring of steel around the system as they close in onEarth, so Ryder pokes holes in it. They're on their own. No support. Navalvessels won't even recognize their callsign. They don't exist... but they'remankind's last hope.
