He paused only long enough to grab the emergency supply pack he kept handy for search and rescue operations, slung a four-millimeter military power rifle over one shoulder, and vanished out the back door at a run.

My sensors detect the EMP of multiple nuclear detonations at a range of approximately 392.25 kilometers, bearing 030 degrees relative. This coincides with the estimated locus of the second Fafnir, and the previously detected heavy gravitic emissions have ceased. I compute a probability of 98.511 percent that the Fafnir has been destroyed by defensive fire, indicating that my Commander’s friend Lorenco Esteban has managed to activate the Fleet Base defenses. I hope that he has not paid with his life for this success.

I detect two new emission sources. Their locations correspond to the projected landing loci of the previously observed assault pods. They match my files for SC-191(b) fusion plants, and are accompanied by narrow-band, encrypted communications transmissions. I attempt to penetrate the com link, but without immediate success. Analysis indicates a sophisticated, multilevel security system.

I devote 1.0091 seconds to consideration of available data and reach a disturbing conclusion. The energy signatures are consistent with the power plants of a Mark XXIV or XXV Bolo; no other mobile unit mounts the SC-191(b). I do not know how the Enemy could have obtained current-generation Bolos, but if these are indeed Mark XXIVs or XXVs, I am grossly overmatched. Despite the superiority of the systems Major Stavrakas devised for me, I compute a probability of 87.46 percent, plus or minus 03.191 percent, that I will be destroyed by two Mark XXIVs, rising to 93.621 percent that I will be destroyed by two Mark XXVs. Yet my duty is clear. However the Enemy may have obtained access to such war machines, I must engage them.

“Colonel Gonzalez, I have detected what may be two hostile Bolos,” the soprano voice said calmly, and Consuela Gonzalez’ olive complexion went sickly gray.

Bolos? In the hands of planet-raiders? It wasn’t possible! Yet she was receiving confirmation of nuclear air-bursts from outlying melon growers over the planetary com net, and the transmissions from Ciudad Bolivar were a babble of hysteria. Her com tech reported the sounds of explosions and heavy weapons fire in the background of the Bolivar transmissions. There could be no doubt that the capital-including her husband and children-was under heavy, ruthless attack, and no one had had even a hint of what was coming, not even a second to organize any sort of defense. Nausea twisted her stomach as she thought of all the civilians who must be dying even as her tank bucketed through the jungle a hundred kilometers to the south, and if the bastards had Bolos “What do you want us to do?” she rasped over the com.

“I will engage them, Colonel. Your own vehicles lack the capability to survive against them. Continue to the specified rendezvous, then advance at your best speed on a heading of two-six-three true for forty-two kilometers before changing to a heading of zero-three-niner. That course will pass to the west of the Enemy’s current location and take you to Ciudad Bolivar in the shortest possible time.”

“You can’t take two other Bolos on your own!”

“Your assistance will not appreciably enhance my own combat capability, Colonel, and your units will be of far more utility to Santa Cruz in Ciudad Bolivar than they will if they are destroyed here. Please proceed as I have advised.”

“All right,” Gonzalez whispered, and then, even knowing it was a machine to whom she spoke– “Vaya con Dios, amiga.”

Colonel Louise Granger stared at her display in shock. She didn’t know what had happened to Fafnir Two-her transport command ship was on the wrong side of the planet, where it had been busy killing the last communications array-but the sudden cessation of all transmissions from Fafnir One was chilling proof her careful battle plan had just been blown to hell. One hadn’t managed to report a damned thing about what was shooting back before whatever it was destroyed her, but she’d gotten off her full load of assault troops and armor to take out the field and the planetary capital before she died. That put her point of destruction well to the north of the Bolo depot, so whatever had killed her, it hadn’t been the Bolo. Granger didn’t know what else on the planet could have done the job, but whatever it was could only have come from the old fleet base, though how anyone could have had time to activate its defenses was beyond her. What she didn’t know was whether or not Fafnir Two had gotten her Golems off before her destruction, and, unlike a Fafnir-class transport-or a full-capability Bolo-a Golem had no subspace com capability. She couldn’t find out what had happened to the huge tanks until her ship swung back over their radio horizon.

She felt the shock and dismay rippling through her operations staff, and she didn’t blame them. But she also knew she had at least three quarters of her brigade’s fighting power down on its primary objective and, presumably, intact. Whatever ground-to-air system had nailed Fafnir One wouldn’t be much use against a ground assault, and she snarled at her shaken officers.

“How the fuck do I know what happened to her?! But whatever it was, it must’ve come from the Fleet Base, and we’ll clear its horizon in fifteen minutes! Get on those command circuits and keep our people moving! Primary objective is now the complete-I repeat, complete-neutralization of that base!”

I continue my efforts to penetrate the Enemy’s communications without success, yet analysis of their patterns convinces me that they are not the Total Systems Data-Sharing net of the Dinochrome Brigade. While they include what can only be interlinked tactical telemetry, they also include what are clearly voice transmissions. This indicates that my opponents are not, in fact, Bolos, and I compute a probability of 56.113 percent that they are actually Golem-IIIs or Golem-IVs. Possession of such vehicles by any Enemy, while still extremely improbable, is more likely than the possibility that the Enemy might somehow have acquired full-capability units of the Line. While the odds against my survival against properly coordinated Golems remain unfavorable, the probability of my destruction against Golem-IIIs drops from 87.46 percent to no more than 56.371 percent, although it remains on the close order of 78.25 percent against Golem-IVs. The probability that I can successfully destroy or at least incapacitate the enemy, on the other hand, has risen to 82.11 percent, regardless of the mark of Golem I may face.

My Battle Center cautions me to assume nothing, yet the intuitive function Major Stavrakas incorporated into my Personality Center argues otherwise. If I assume that these are, indeed, Golems and plan my tactics accordingly, my chance of victory-and survival-will be considerably enhanced. If I act on that assumption and it proves incorrect, my destruction will be assured. I consider for 0.90112 seconds and reach conclusion. I will assume my opponents are Golems.

Two huge war machines, each crewed by three very anxious humans, forged through the jungle like impatient Titans, bulldozing their way through hundred-meter trees while their commanders shouted at one another.

“It had to be the frigging Bolo!” Golem-Two’s commander bellowed finally, stunning his counterpart in Golem-One into silence with sheer volume. “And if it was, it’s coming after our asses next! So shut the hell up and listen to me, goddamn it!”

“If there’s a live Bolo out there, then let’s get the fuck out of here!”

“No, damn it! If we run, the damned thing’ll come right up our asses, and we’ve already lost both Fafnirs. If it gets to the field, there’s no way in hell Granger or Matucek will risk trying to pick us up-it’d swat ‘em like flies, if they did. If we want off this planet, we’ve gotta kill the fucking thing, and it’s only a Mark XXIII!”
