Jack Ryan 9 - Executive Orders (148 page)

It was faster for the 155mm guns. These, too, were gunning for their enemy counterparts, and their rounds were every bit as accurate as the rockets. It was the most mechanistic of military activities. The gun did the killing and the people served the gun. They couldn't see their work, and in this case didn't even have a forward-observer to tell them how they were doing, but they'd learned that with GPS doing the aiming, it didn't matter—and if things went as planned, they would later see the results of their deadly work.

Perversely, those with direct views of the advancing enemy fired last, the tankers waiting for the word, delivered as company commanders fired first for their units.

For all its lethality, the fire-control system for the Abrams tank is one of the simplest mechanisms ever placed in the hands of soldiers, and even easier to use than the million-dollar crew-training simulators. The gunners each had assigned sectors, and the initial rounds fired by the company commanders had been HEAT—high-explosive antitank—rounds, which made a distinctive visual signature. Tanks were assigned areas left or right of those first kills. The thermal-imaging viewing systems keyed on heat, infrared radiation. Their targets were warmer than the desert landscape at night and announced their presence as clearly as lightbulbs. Each gunner was told what area to pick from, and each selected an advancing T-80. Centering the target in the sight, the laser buttons were depressed. The beam went out to the target and reflected back. The return signal told the ballistic computer the target's distance, speed, and direction of movement. Other sensors told it the outside temperature, the temperature of the ammunition, atmospheric density, wind direction and speed, the condition of the gun (hot ones droop), and how many shells had been fired through the tube to this point in its career. The computer digested this and other information, processed it, and when finished, flashed a white rectangle in the gunsight to tell the gunner the system was on target. Then it was just a matter of his closing his index fingers on the yoke's twin triggers. The tank lurched, the breech surged back, the muzzle flash blinded the sight momentarily, and the “sabot” rounds streaked downrange at more than a mile a second. The projectiles were like overly thick arrows, less than the length of a man's arm, and two inches in diameter, with stubby fins on the tail that burned from air friction in their brief flight, and trailing tracers for the tank commander to watch the “silver bullets” all the way in.

The targets were Russian-made T-80s, old tanks with old design histories. They were much smaller than their American adversaries, mainly due to their inadequate engine power, and their diminished size had made for a number of design compromises. There was a fuel tank in the front, the line for which went along the turret ring. Gun rounds were fitted in slots that nested in the rear fuel tank, so that their ammunition was surrounded by diesel fuel. Finally, to save on turret space, the loader had been replaced by an automated loading system, which in addition to being slower than a man, also required that a live round be in the open in the turret at all times. It might not have made all that much of a difference in any case, but it did make for spectacular kills.

The second T-80 to die took a “silver bullet” at the base of the turret. The incoming round obliterated the fuel line first of all, and in the process of crashing through the armor created a lethal shower of fragments moving at over a thousand meters per second in the cramped confines, caroming off the inner surface and chopping the crewmen to bits; at the same time the ready round ignited on its tray and other rounds exploded in their racks. The crew was already dead when the ammunition exploded, also setting off the fuel and creating an explosion which blew the heavy turret fifty feet straight up in what the Army called a “catastrophic kill.” Fifteen others died the same way in the space of three seconds. The Immortals Division's advance guard evaporated in ten more, and the only resistance they were able to offer was that the pyres of their vehicles obscured the battlefield.

Fire shifted at once to the main body, three battalions advancing on line, now just over three thousand meters away, a total of just over a hundred fifty advancing toward a battalion of fifty-four.

The commanders of the Iranian tanks were mainly still out of their turrets, the better to see, despite their having seen the rockets lifting off several miles downrange. They next saw a linear ripple of white and orange three kilometers in the distance, followed by explosions to their direct front. The quicker of the officers and conscripted tank commanders ordered their gunners to get rounds off at the muzzle flashes, and no less than ten did shoot, but they hadn't had time to gauge the range, and all their rounds fell short. The Iranian crews were drilled in what to do, and they hadn't as yet had time for fear to replace shock. Some started reload cycles, while others worked their range finders to get off properly aimed rounds, but then the horizon turned orange again, and what followed scarcely gave them the time to take note of the change of color in the sky.

The next volley of fifty-four main-gun rounds found forty-four marks, ten of the T-80s being double-targeted. This was less than twenty seconds into the engagement.

“Find one still moving,” one E-6 tank commander said to his gunner. The battlefield was lighting up now, and the fireballs interfered with the thermal viewers. There. The gunner got his laser range—3,650m—the box came up, and he fired. The sights blanked, then came back, and he could see the tracer of his round arcing flat across the desert, all the way in—

“Target!” the commander said. “Shift fire.”

“Identified—got one!”

“Fire!” the commander ordered.

“On the way!” The gunner fired his third round of the half-minute, and three seconds later, another T-80 turret became a ballistic object.

Just that fast, the tank phase of the battle was over.

The Bradleys were engaging the advancing BMPs, their Bushmaster cannons reaching out. It was slower for them, the range more difficult for their lighter guns, but the result was just as final.

T
HE COMMANDER OF
the Immortals was just approaching the trail elements of the lead brigade when he saw the rockets fly. Telling his driver to pull over, he stood and turned in his command vehicle and saw the secondary explosions of his divisional artillery array, when, turning back forward, he saw the second volley of Eddington's tanks. Forty percent of his combat power had disappeared in less than a minute. Even before the shock hit him, he knew that he'd walked into an ambush—but of what?

which had robbed the Immortals of their artillery had come from the east, not the south. It was Hamm's gift to the National Guardsmen, who were unable to go after the Iranian guns themselves with the existing fire plan. Blackhorse's MLRS had done that, then shifted fire to make way for the regiment's Apache attack helicopters, which were striking deep, actually beyond the II Corps units now being engaged by the three ground squadrons.

The division of labor on this battlefield had been determined in principle the previous day, and developments had not changed anyone's thoughts. Artillery would initially target artillery. Tanks would target tanks. The helicopters were out to kill commanders. The Immortals Division CP had stopped twenty minutes earlier. Ten minutes before the first rocket launch, Apache-Kiowa teams looped around from the north, approaching from the rear and heading for the places from which the radio signals were emitting. First would come the division-level targets, followed by the brigades.

The Immortals' staff was just coming to terms with the incoming signals. Some officers requested confirmation or clarification, information needed before they could react properly to the situation. That was the problem with command posts. They were the institutional brains of the units they commanded, and the people who made up the decision process had to be together to function.

From six kilometers away, the collection of vehicles was obvious. Four SAM-shooters were oriented south, and there was a ring of AAA guns, too. Those went first. The Apaches of P-(Attack)-Troop stopped in place, picking a spot with nothing dangerous around, and hovering at about a hundred feet. Front-seated gunners, all of them young warrant officers, used optical equipment to zoom in, selected the first group of targets, and selected Hellfire laser-guided missiles. The first launch was made by surprise, but an Iranian soldier saw the flash, and shouted to a gun crew, which slewed its guns around and started shooting before the missiles were all the way on. What followed was a madhouse. The targeted Apache dodged left, accelerating sideways at fifty knots to throw them off, but also ruining the aim of the startled gunner, who had to shoot again, as the first missile went wide. The other AH-64s were not hampered, and of their six launches, five hit. In another minute, the antiair problem was neutralized, and the attack choppers closed. They could see people running now, out and away from the command tracks. Some soldiers in the command security group started firing their rifles into the sky, and there was more structured activity from machine-gunners, but surprise was on the other side. The gunners fired 2.75-inch rockets to blanket the area, Hellfires to eliminate the few remaining armored vehicles, and then shifted to their 30mm cannon. In display of their rage, they closed in now, like the oversized insects they appeared to be, buzzing and slipping from side to side while the gunners looked for people the heavier weapons had missed. There was noplace to hide on the flat terrain, and the human bodies glowed on the dark, colder surface, and the gunners hunted them down in groups, in pairs, and finally one by one, sweeping across the site like harvesters. In their pre-mission discussion on the flight line, it had been decided that, unlike in 1991, helicopters would not accept surrender in this war, and the 30mm projectiles had explosive tips. P-Troop—they called themselves the Predators—lingered for ten minutes before they were satisfied that every single vehicle was destroyed and every moving body dead before they twisted in the sky, dipped their noses, and headed back east for their rearm points.

T
HE PREMATURE ATTACK
on II Corps's reconnaissance element had started one part of this battle a little too early, and alerted a reasonably intact tank company sooner than intended, but the enemy tanks were still white blobs on a black background, and less than four thousand meters away.

“Battlestars engage,” B-Troop's commander ordered, firing off his first round, soon to be followed by eight more. Six hit, even at this extreme range, and the attack by the Blackhorse on II Corps began even before the first MLRS volley. The next volley was delivered on the move, and five more tanks exploded, their return rounds falling short. It was a little harder to hit this way. Though the gun was stabilized, hitting a bump could throw the aim off, and misses were expected, if not exactly welcomed.

B-Troop's tanks were spaced fully half a kilometer apart, and each had a hunting zone exactly that wide, and the farther they went, the more targets appeared. The Bradley scout vehicles hung back a hundred yards or so, and their gunners looked for infantry who might wield antitank weapons. II Corps's two divisions were spread across twenty miles of linear space and about eight miles of depth, so said the IVIS gear. In ten minutes, B-Troop chopped its way through a battalion diminished by the Saudis and now erased by the Americans. The bonus came ten minutes later, when they spotted a battery of artillery setting up. The Bradleys got those, sweeping the area with their 25mm cannon and adding to the fireballs that gave the lie to the sunset only four hours old.

asked. He'd heard the amazement himself over his battalion net: “Is that all?” more than one sergeant had asked aloud. It was crummy radio discipline, but everyone was thinking the same thing.

But there was more to do than admire the work. Eddington lifted his radio handset and called for his brigade S-2.

“What's Predator tell us?”

“We have two more brigades still southbound, but they slowed some, sir. They're roughly nine klicks north of your line on the near one, and twelve on the far one.”

HE GENERAL WAS
still in the same place, with death before and behind. Scarcely ten minutes had passed. Three tanks and twelve BMPs had run backward, stopping at a depression and holding position while they waited for instructions. There were men coming back now, too, some wounded, most not. He could not scream at them. If anything, the shock of the moment was harder on him than it was on them.

He'd already tried contacting his divisional command post, but gotten only static in return, and for all his experience in uniform, his time in command, the schools he'd attended, and the exercises he'd won and lost—nothing had prepared him for this.

But he still had more than half a division to command. Two of his brigades were still fully intact, and he hadn't come here to lose. He ordered his driver to turn and head back. To the surviving elements of the lead brigade went orders to hold until further word. He had to maneuver. He'd run into a nightmare, but it couldn't be everywhere.

“W
HAT DO YOU
propose, Eddington?”

“General Diggs, I want to move my people north. We just ate up two tank brigades easier'n a plate full of grits. The enemy's artillery is largely destroyed, sir, and I have a clear field in front of me.”

“Okay, take your time and watch your flanks. I'll notify B

“Roger that, sir. We'll be moving in twenty.”

They'd thought about this possibility, of course. There was even a sketch plan on the maps. L

They'd have to move slowly because of the darkness, the unfamiliar ground, and the fact that it was only half a plan, but the activation code word was N
