Bai was standing calmly by the door, a hint of a smile on his face as he looked around at what must have been some pretty stunned expressions. "I'm sure all of you know," he said, "that using either a lift pack or exoskeleton muscle enhancers would be foolhardy in such a confined room. Um? So watch again."

His knees bent a few degrees, and with the same thump-thump he was back on the dais. "All right," he said. "Who saw what I did?"

Silence... and then a hand went tentatively up. "You bounced off the ceiling, I think," the recruit said, a bit uncertainly. "Uh... your shoulders took the impact?"

"In other words, you didn't really see," Bai nodded. "I actually flipped halfway over on the way up, took the impact with my feet, and continued around to be upright when I landed."

Jonny's mouth felt a little dry. The ceiling was no more than five meters up. To have done that much maneuvering in that small a space...

"The point, aside from the power and precision of the jump itself," Mendro said, "is that even you, who knew what was going to happen, couldn't follow Bai's movement. Consider how it would work against a roomful of Trofts who weren't expecting it. Next—"

He broke off as the door opened and one more recruit came in. "Viljo?" Bai asked, retrieving the comboard at his feet.

"Yes, sir," the newcomer nodded. "Sorry I'm late, sir—the registration people were running slow."

"Oh?" Bai waved the comboard. "Says here you went through the line at 1450. That's—let's see—seventeen minutes before Moreau, who got here seven minutes earlier than you did. Um?"

Viljo turned a bright red. "I... guess maybe I got a little lost. Sir."

"With all the signs posted around the complex? Not to mention all the regular Army personnel wandering around? Um?"

Viljo was beginning to look like a hunted animal. "I... I stopped to look at the exhibits in the entry corridor, sir. I thought this room was closer than it was."

"I see." Bai gave him a long, chilly look. "Punctuality, Viljo, is a mark of a good soldier—and if you plan to be a Cobra it's going to be an absolute necessity. But even more important are honesty and integrity in front of your teammates. Specifically, it means that when you crusk up, you damn well better not try to push the blame onto someone else. Got that?"

"Yes, sir."

"All right. Now come up here; I need an assistant for this next demonstration."

Swallowing visibly, Viljo unglued himself from the floor and threaded his way through the chairs to the dais. "What I showed you a minute ago," Bai said, once again addressing the entire room, "was essentially a party trick, though with some obvious military applications. This, now, I think you'll find along more practical lines."

From his tunic, he produced two metal disks, each ten centimeters in diameter with a small black inset in the center. "Hold the one in your left hand sideways," Bai instructed Viljo, "and when I give the word, throw the other toward the back of the room."

Mendro had meantime gone to one of the room's back corners. Taking a few steps off to the side, Bai checked positions and bent his knees slightly. "All right: now."

Viljo lofted the disk toward the door. Behind him, Jonny sensed Mendro's leap and catch, and an instant later the disk was shooting back toward Bai. In a smooth motion that was again too fast to follow, Bai fell to the side, out of the disk's path... and as he rolled again to one knee, two needles of light flashed in opposite directions from his outstretched hands. Viljo's surprised yelp was almost covered up by the crash of the flying disk against the wall.

"Good," Bai said briskly, getting to his feet and heading over to retrieve the first disk. "Viljo, show them yours."

Even from his distance Jonny could see the small hole just barely off-center through the black inset. "Impressive, um?" Bai said, stepping back up on the dais and presenting the other target. "Of course, you can't always expect the enemy to hold still for you."

This shot hadn't been nearly as clean. Only the very edge of the black showed the laser's mark, and when the light hit it right Jonny could see that the adjacent metal was rippled with the heat. Still, it was an impressive performance—especially as Jonny had no idea where Bai had been hiding his weapons.

Or where they were now, for that matter.

"That gives you an idea of what a Cobra can do," Mendro said, returning to the front of the room and sending Viljo back to find a seat. "Now I'd like to show you a little of the nuts and bolts involved." Retrieving the comboard, he keyed in an instruction, and a full-sized image of a man appeared beside him. "From the outside a Cobra is virtually indistinguishable from any normal civilian. However, from the inside—" The hologram's exterior faded to a blue skeleton with oddly-shaped white spots scattered randomly around. "The blue is a ceramic laminae which makes all the major and most of the minor bones unbreakable, for all practical purposes. That, along with some strategic ligament strengthening, is half the reason Cee-three Bai was able to pull off those ceiling jumps without killing himself. The non-laminated areas you can see are there to allow the bone marrow to continue putting red blood cells into the system." Another touch on the comboard and the piebald skeleton faded to dull gray, forming a contrast to the small yellow ovoids that appeared at joints all over the hologram. "Servomotors," Mendro identified them. "The other half of the ceiling jump. They act as strength multipliers, just like the ones in standard exoskeletons and fighting suits, except that these are particularly hard to detect. The power supply is a little nuclear goody here—" he pointed to an asymmetric object situated somewhere in the vicinity of the stomach"—and I'm not going to explain it because I don't understand it myself. Suffice it to say the thing works and works well."

Jonny thought back to Bai's incredible jumps and felt his stomach tighten. Servos and bone laminae were all well and good, but a trick like that could hardly be learned overnight. Either this Cobra training was going to take months at the minimum, or else Bai was an exceptionally athletic man... and if there was one thing Jonny knew for certain, it was that he himself hadn't been selected for this group because of any innate gymnastic abilities. Apparently the Army was getting set for a long, drawn-out conflict.

On the dais, the hologram had again changed, this time marking several sections in red. "Cobra offensive and defensive equipment," Mendro said. "Small lasers in the tips of both little fingers, one of which also contains the discharge electrodes for an arcthrower—capacitor in the body cavity here. In the left calf is an antiarmor laser; here are the speakers for two different types of sonic weapons; and up by the eyes and ears are a set of optical and auditory enhancers. Yes—question?"

"Recruit MacDonald, sir," the other said with military correctness, a slight accent burring his words. "Are these optical enhancers like the targeting lenses of a fighting suit, where you're given a range/scale image in front of your eyes?"

Mendro shook his head. "That sort of thing is fine for medium- and long-range work, but pretty useless for the infighting you may have to do. Which brings us to the real key of the whole Cobra project." The red faded, and inside the skull a green walnut-sized object appeared, situated apparently directly beneath the brain. From it snaked dozens of slender filaments, most of them paralleling the spinal column before separating off to go their individual ways. Looking at it, Jonny's thoughts flashed back to a picture from his old fourth-grade biology text: a diagram showing the major structures of the human nervous system....

"This," Mendro said, wagging a finger through the green walnut, "is a computer—probably the most powerful computer of its size ever developed. These optical fibers—" he indicated the filament network—"run to all the servos and weapons and to a set of kinesthetic sensors implanted directly in the bone laminae. Your targeting lenses, MacDonald, still require you to do the actual aiming and firing. This nanocomputer gives you the option of having the whole operation done automatically."
