“Okay, move to the center and clear out the rubble. Take your time. No rush until you pull the pin.”

“Sure, Sergeant.” We could hear small echoes of rocks clattering, sound conduction through her boots. She didn’t say anything for several minutes. “Found bottom.” She sounded a little out of breath.

“Ice or rock?”

“Oh, it’s rock, Sergeant. The greenish stuff.”

“Use a low setting, then. One point two, dispersion four. ”

“God darn it, Sergeant, that’ll take forever.”

“Yeah, but that stuff’s got hydrated crystals in it — heat it up too fast and you might make it fracture. And we’d just have to leave you there, girl. Dead and bloody.”

“Okay, one point two dee four.” The inside edge of the crater flickered red with reflected laser light.

“When you get about half a meter deep, squeeze it up to dee two.”

“Roger.” It took her exactly seventeen minutes, three of them at dispersion two. I could imagine how tired her shooting arm was.

“Now rest for a few minutes. When the bottom of the hole stops glowing, arm the charge and drop it in. Then walk out, understand? You’ll have plenty of time.”

“I understand, Sergeant. Walk out.” She sounded nervous. Well, you don’t often have to tiptoe away from a twenty-microton tachyon bomb. We listened to her breathing for a few minutes.

“Here goes.” Faint slithering sound, the bomb sliding down.

“Slow and easy now. You’ve got five minutes.”

“Y-yeah. Five.” Her footsteps started out slow and regular. Then, after she started climbing the side, the sounds were less regular, maybe a little frantic. And with four minutes to go.

“Shit!” A loud scraping noise, then clatters and bumps. “Shit-shit.”

“What’s wrong, private?”

“Oh, shit.” Silence. “Shit!”

“Private, you don’t wanna get shot, you tell me what’s wrong!”

“I … shit, I’m stuck. Fucken rockslide … shit … DO SOMETHING! I can’t move, shit I can’t move I, I—”

“Shut up! How deep?”

“Can’t move my, shit, my fucken legs. HELP ME—”

“Then Goddammit use your arms — push! You can move a ton with each hand.” Three minutes.

She stopped cussing and started to mumble, in Russian, I guess, a low monotone. She was panting, and you could hear rocks tumbling away.

“I’m free.” Two minutes.

“Go as fast as you can.” Cortez’s voice was flat, emotionless.

At ninety seconds she appeared, crawling over the rim. “Run, girl … You better run.” She ran five or six steps and fell, skidded a few meters and got back up, running; fell again, got up again

It looked as though she was going pretty fast, but she had only covered about thirty meters when Cortez said, “All right, Bovanovitch, get down on your stomach and lie still.” Ten seconds, but she didn’t hear or she wanted to get just a little more distance, and she kept running, careless leaping strides, and at the high point of one leap there was a flash and a rumble, and something big hit her below the neck, and her headless body spun off end over end through space, trailing a red-black spiral of flash-frozen blood that settled gracefully to the ground, a path of crystal powder that nobody disturbed while we gathered rocks to cover the juiceless thing at the end of it…

That night Cortez didn’t lecture us, didn’t even show up for nightchop. We were all very polite to each other and nobody was afraid to talk about it.

I sacked with Rogers — everybody sacked with a good friend — but all she wanted to do was cry, and she cried so long and so hard that she got me doing it, too.

“Fire team A — move out!” The twelve of us advanced in a ragged line toward the simulated bunker. It was about a kilometer away, across a carefully prepared obstacle course. We could move pretty fast, since all of the ice had been cleared from the field, but even with ten days, experience we weren’t ready to do more than an easy jog.

I carried a grenade launcher loaded with tenth-microton practice grenades. Everybody had their laser-fingers set at a point oh eight dee one, not much more than a flashlight. This was a simulated attack — the bunker and its robot defender cost too much to use once and be thrown away.

“Team B, follow. Team leaders, take over.”

We approached a clump of boulders at about the halfway mark, and Potter, my team leader, said, “Stop and cover.” We clustered behind the rocks and waited for Team B.

Barely visible in their blackened suits, the dozen men and women whispered by us. As soon as they were clear, they jogged left, out of our line of sight.

“Fire!” Red circles of light danced a half-klick downrange, where the bunker was just visible. Five hundred meters was the limit for these practice grenades; but I might luck out, so I lined the launcher up on the image of the bunker, held it at a forty-five degree angle and popped off a salvo of three.

Return fire from the bunker started before my grenades even landed. Its automatic lasers were no more powerful than the ones we were using, but a direct hit would deactivate your image converter, leaving you blind. It was setting down a random field of fire, not even coming close to the boulders we were hiding behind.

Three magnesium-bright flashes blinked simultaneously about thirty meters short of the bunker. “Mandella! I thought you were supposed to be good with that thing.”

“Damn it, Potter — it only throws half a klick. Once we get closer, I’ll lay ’em right on top, every time.”

“Sure you will.” I didn’t say anything. She wouldn’t be team leader forever. Besides, she hadn’t been such a bad girl before the power went to her head.

Since the grenadier is the assistant team leader, I was slaved into Potter’s radio and could hear B team talk to her.

“Potter, this is Freeman. Losses?”

“Potter here — no, looks like they were concentrating on you. ”

“Yeah, we lost three. Right now we’re in a depression about eighty, a hundred meters down from you. We can give cover whenever you’re ready.”

“Okay, start.” Soft click: “A team, follow me.” She slid out from behind the rock and turned on the faint pink beacon beneath her powerpack. I turned on mine and moved out to run alongside of her, and the rest of the team fanned out in a trailing wedge. Nobody fired while A team laid down a cover for us.

All I could hear was Potter’s breathing and the soft crunch-crunch of my boots. Couldn’t see much of anything, so I tongued the image converter up to a log two intensification. That made the image kind of blurry but adequately bright. Looked like the bunker had B team pretty well pinned down; they were getting quite a roasting. All of their return fire was laser. They must have lost their grenadier.

“Potter, this is Mandella. Shouldn’t we take some of the heat off B team?”

“Soon as I can find us good enough cover. Is that all right with you? Private?” She’d been promoted to corporal for the duration of the exercise.

We angled to the right and lay down behind a slab of rock. Most of the others found cover nearby, but a few had to hug the ground.

“Freeman, this is Potter.”

“Potter, this is Smithy. Freeman’s out; Samuels is out. We only have five men left. Give us some cover so we can get—”

“Roger, Smithy.” Click. “Open up, A team. The B’s are really hurtin’.”

I peeked out over the edge of the rock. My rangefinder said that the bunker was about three hundred fifty meters away, still pretty far. I aimed a smidgeon high and popped three, then down a couple of degrees, three more. The first ones overshot by about twenty meters; then the second salvo flared up directly in front of the bunker. I tried to hold on that angle and popped fifteen, the rest of the magazine, in the same direction.

I should have ducked down behind the rock to reload, but I wanted to see where the fifteen would land, so I kept my eyes on the bunker while I reached back to unclip another magazine—
