War Is Virtual Hell

The First Company of the 12th Armored Cavalry Regiment prepared for virtual battle.

At the Combined Arms and Tactical Training Center (CATTC) in Fort Knox, Ky., the troops prepared to enter SIMNET - a virtual war delivered via network links. With the almost Disney-like mimicry typical of SIMNET operations, the warriors were briefed in an actual field command-post, with folding camp-stools, fly swatters, and stenciled jerry cans. The young tankers wore green- and-brown forest camouflage fatigues, black combat boots, and forage caps.

Their command-post canvas tent was pitched inside the giant CATTC barn, right in the midst of silent rows of plastic tank simulators.

The Americans listened to a British officer on NATO exchange, Maj. Rogers, a two-year veteran of Fort Knox's simulator network. The major wore British olive- green, with rolled sleeves and gold-crowned epaulets and a Union Jack at the shoulder. He swiftly explained the tactical situation with deft scribbles on the plastic overlay covering a large topographical map.

Today's engagement would take place in a digital replica of California's Mojave Desert, the bleak, much-mangled terrain that is the heavy-armor stomping grounds of the US Army's National Training Center. Thanks to the Defense Advanced Research Projects Agency (DARPA), the Defense Mapping Agency, and the Army's Topographic Engineering Center, the US military's vast Mojave acreage had been replicated virtually. The virtual Mojave is now available for daily use even in distant Fort Knox (and in an increasing number of other simulation centers around the planet).

The NTC's Mojave was a very harsh terrain, a hell of a place to lose a cow or to throw a tank track, and today it was worse yet, because it was swarming with the Opposing Forces.

The Threat were on their way in overwhelming numbers. Their assault force was four times larger than the beleaguered Americans, and they were blitzkrieging headlong in Soviet T-72 heavy tanks and mechanized transports.

The unlucky One-Twelve Cav were to take their initial stand in the ruggedly digitized Mojave hills on a baseline code-named Purple. Their orders were to fight in their sector, delaying the advance as best they could, while retreating in good order to Baseline Amber, where the survivors (if there were any) were to take another stand.

The attacking enemy would advance from west to east. That much was already known. But the exact enemy tactics were obscured by the fog of war.

The US company commander, Capt. Van Aken, studied the terrain and deployed his meager forces with care. Alpha Platoon to guard the center. Bravo Platoon to the north. Charlie Platoon to the south. The command post to the rear, near Baseline Amber. And the scouts, in their swift but lightly armored Bradleys, to range ahead of Baseline Purple.

The One-Twelve Cav had their orders. They understood their strategy. They left the command post for the squat plastic ranks of simulators. The Jacuzzis of Death.

From the outside, a SIMNET M1 Abrams tank simulator is clearly not a tank. It looks like an oddly humped gray fiberglass shower-stall. The simulator is, in fact, built by Jacuzzi from the same materials as a whirlpool bath. Its interior, however, is designed to psycho-logically replicate the basic tank experience, and it does.

Inside, the simulator is the proper shape and size for a tank's crew chamber. It makes all the proper sounds: the loud engine whine, the ominous rumble of treads, the multi-ton coffee-grinder racket as the turret slews, the concussive thud of the main gun firing. It has the instruments of a tank, though many of those controls are nonfunctional and only painted-on. There are no actual 40- pound high-explosive shells inside simulators, though the loader, by design, must still go through the physical motions of cramming them into the ca

A real M1 Abrams battle tank is a nightmarish vehicle. It weighs 70 tons. It's 26 feet long and 12 feet wide. It carries a 120-millimeter ca

It is also a horrible place in which to die. The Abrams holds four men. Three of them (the tank commander, the gu

Almost every visible surface within the chamber is covered with readout screens, switches, sensors, gauges, and maintenance monitors. The area around the tank commander's tall black stool has a weirdly shaped black joystick, a targeting scope, and two flat screens with buttons bearing cryptic acronyms. These big square buttons are designed to be pressed by hands encased in chemical-warfare gauntlets. They're like a lethal parody of the child-sized buttons on a My First Sony.

Tanks are, of course, very well-armored vehicles, but there is very little on earth that can resist a 120-millimeter uranium slug traveling at a mile-per- second. Anything hit by this projectile instantly buckles and splatters. Modern tank-to-tank warfare is extremely lethal and the exchange of direct fire generally lasts only seconds.

Those seconds are precious, so time spent inside a simulator is not a picnic. Simulators are not toys. They are "fun" in some sense, but only about as much fun as an actual no-kidding tank. You can drive these simulators across cyberspace landscapes, coordinate their tactics, advance and retreat, aim their ca

The One-Twelve Cav deployed to their virtual tanks, opened the thick plastic doors on their hefty refrigerator-style hinges, took their posts at the black plastic seats, and were sealed inside. The drivers were also formally encased in their own separate plastic sarcophagi.

They started their virtual engines. They began exchanging virtual radio traffic. They examined their virtual navigation, and squinted at the desert-colored polygons in their vision-blocks. From the Ethernet lines dangling from metal frames overhead, SIMNET packets began to flow to and from the gloss-black Computer Image Generators, and the SIMNET recording angel, the big network machine they called "Radcliff," started to monitor the battle.
