Down the stairs, whining ever so gently, the hulking machine moved along the hallway toward the office suite that held the machine gun nest.
It found the people and the gun with its UWB radar. There were four men behind an office wall. One man was leaning out the window, looking at the street below, and the others were loading the gun. Fred detected the metallic sounds of the ammo belt being inserted in the gun and the chamber being charged.
“How thick is that wall?” Cole asked the operator who was monitoring Fred’s progress. Cole was standing behind him, looking over his shoulder.
“A few inches, I think. Typical commercial construction.”
“Have him shoot through it. If that doesn’t work, have him punch a hole in it and shoot through the hole.”
The robot’s minigun moved to slave itself to the aiming point, then fired. The soldier leaning out the window fell forward until he was lying across the sill.
Three more shots followed in less than a second. The other men around the machine gun fell to the floor.
“We’re going to need that gun,” Cole said. “Have Fred bring it along.”
“It won’t be able to maneuver very well carrying the launchers, the machine gun, and some ammo belts,” the operator objected.
“If it needs to move quickly, it can drop anything that hinders it.”
Dog and Easy York fought their way along the tops of the buildings toward the tank strongpoint at the Nathan-Waterloo roads intersection, one on each side of Nathan Road. On top of the buildings the fighting machines were at peak efficiency — there were no civilian spectators and no friendly soldiers, so everyone they saw they shot.
Running, leaping from roof to roof, scrambling up or down, shooting at — and hitting — every target that the sensors detected, the Yorks covered six blocks quickly.
Each York carried an antitank rocket, so when they were in range they stepped to the edge of the buildings and brought the launch tubes to firing position. The Yorks fired their rockets simultaneously.
Flames jetted from the open hatches of the tanks as the rockets penetrated the relatively thin upper deck armor and exploded inside.
The one tank that survived was half buried inside a corner store, with its gun punched through the store and pointing down Nathan Road. When the other two tanks were hit, the commander of this tank screamed at his driver, “Go, go, go!”
The driver popped the clutch and the tank leaped forward, collapsing the corner of the building that sheltered it. It accelerated across the sidewalk and bulled through a line of parked cars.
The tank crossed Nathan at an angle and rode up on the cars parked on the left side of the road, crushing them, as the driver struggled to turn the tank to the right to keep it in the road. The turn kept his left tread on top of the parked cars, which were squashed and ejected backward as the tread fought for purchase. PLA soldiers hiding in shop doorways and behind cars ran for their lives.
Into this bedlam the Yorks began tossing grenades. One of the grenades ignited fuel trickling from a crushed gasoline tank, and soon the car was burning in the street and casting an eerie glow on the storefronts and the wreckage.
Dog York was throwing its last grenade when it was hit in the back by two bursts of rifle bullets. It spun and found two PLA soldiers running toward it, shooting. They probably intended to push or throw it over the edge of the building, but they had no chance. With bullets bouncing off its torso, the robot leaped and grabbed each by the neck with its powerful titanium claws, killing them instantly. Then it tossed the bodies off the roof.
Easy and Dog descended the stairs in their respective buildings, hunting for PLA soldiers. There was a machine gun nest in a third-floor apartment of Easy’s building. It tore its way through walls, killed the soldiers, and picked up the gun. With ammo belts draped over its shoulders, the York unit went into the hallway and descended the stairs.
Someone dropped a grenade down the staircase. The thing exploded a few feet from Easy, showering it with shrapnel, but it kept going.
Out in the street it attacked the soldiers there with the machine gun and the few rounds remaining in the minigun. The tank was long gone, careening south on Nathan Road, leaving a trail of crushed and damaged vehicles in its wake.
Dog came out of a building on the other side and began working in tandem with Easy, killing every enemy soldier they detected.
One soldier huddled behind a car heard a running York coming at him and threw down his rifle. He stood with his hands in the air.
The Yorks ignored him.
Seeing this, more and more soldiers threw down their weapons and stood, almost two hundred of them.
The shooting stopped. The two Yorks came to a halt in the center of the intersection back-to-back, one holding a machine gun, their heads turning back and forth, the barrels of their miniguns spinning silently.
In the control room, Virgil Cole looked the situation over, then ordered the operator to stop the spinning miniguns to save battery power.
The runaway tank tore south on Nathan Road, forcing the PLA soldiers in the street to scurry for cover or get run over. The panicked tank commander kept the hatch open so he could look up at the buildings, spot enemies with antitank weapons.
Alvin York, running north up the street, saw the tank coming and got between two parked vehicles, out of the way. As the tank passed, Alvin chased it.
The York was capable of a sustained pace of twenty miles per hour and even higher speeds in short, battery-draining bursts. Alvin used that speed now to catch the tank.
The tanker must have sensed the York coming, for he turned and looked back just as Alvin leaped onto the back of the machine and aimed the minigun at the tanker’s head. One shot in the head killed the man.
Alvin pulled the body from the hatch and threw it backward into the street.
Then the robot climbed up on the turret and descended into the tank.
The driver pulled a pistol and emptied it at Alvin. Bullets ricocheting inside the steel compartment killed the gunner, who slumped in his seat.
The out-of-control tank smashed over a line of cars, crossed a sidewalk, and buried itself inside a shop selling electronic gadgets. With the treads still spinning, the tank tore out the building’s supports, causing it to collapse.
Inside the tank Alvin York reached for the screaming driver and tore his head from his body.
“Jesus H. Christ!” Virgil Cole exclaimed as he witnessed the gruesome scene on the computer monitor, two miles away. “Couldn’t you just have the York shoot the guy?”
“He’s on full automatic, sir,” the controller responded. “The program is designed to allow him to conserve as much ammunition as possible.”
“Sweet Jesus,” Cole said, then turned away so he wouldn’t have to look.
The Bob York robot saw the PLA soldiers advancing south in the subway tunnel toward the Jordan Road station and opened fire. It was standing in total darkness, partially hidden behind a pillar between the two train tracks. Wu had his men on the platforms on each side where they could not be hit by ricocheting bullets.
When the York opened fire, Wu shoved the muzzle of the machine gun he was manning around the edge of the platform and triggered a long burst. On the other platform another rebel did the same. The muzzle flashes lit the scene in a ghastly flickering light.
Wu waggled the barrel of the weapon, hosing the bullets into the tunnel. Up tunnel he glimpsed showers of sparks where the bullets bounced off concrete.
In that dark, closed space the din of the hammering machine guns and the strobing muzzle flashes were almost psychedelic.
