"Now, there at center screen, Mr. Counselor, you see that big blue rectangular formation. Actually that's the opening of Grand Crevasse, emerges through an ice tunnel, you know. Understand the Crevasse is a crustal fault, a part of the same formation that created the thermal sink from which the Complex draws its energy. Splendid spot for an ambush, of course, if we had the capability. Enemy has little option; like a highway in there-armor can move up at flank speed. Above, the badlands, where we must operate. Now, over to the left, you see that smoke, or dust or whatever. That represents the western limit of the unavoidable gap in General Bates's line. Dust raised by maneuvering Mark XV's, you understand. Obsolete equipment, but we'll do what we can with them. Over to the right, in the distance there, we can make out our forward artillery emplacement of the Threshold Line. Pitiful, really. Yes, Mr. Counselor, there is indeed a gap precisely opposite the point where the lead units of the enemy are expected to appear. Clearly anything in their direct line of advance will be annihilated; thus General Bates has wisely chosen to dispose his forces to cover both enemy flanks, putting him in position to counterattack if opportunity offers. We must, after all, sir, use what we have. Theoretical arms programmed for fiscal ninety are of no use whatever today. Umm. As for that, one must be flexible, modifying plans to meet a shifting tactical situation. Faced with the prospect of seeing the enemy drive through our center and descend unopposed on the vital installations at Cold City, I have, as you see, decided to order General Bates to make use of the experimental Mark XX. Certainly-my decision entirely. I take full responsibility."

I advance over broken terrain toward my assigned position. The prospect of action exhilarates me, but my assessment of enemy strength indicates they are fielding approximately 17.4 percent greater weight of armor than anticipated, with commensurately greater firepower. I compute that I am grossly overmatched. Nonetheless, I shall do my best.

"There's no doubt whatever, gentlemen. Computers work with hard facts. Given the enemy's known offensive capability and our own defensive resources, it's a simple computation. No combination of the manpower and equipment at our command can possibly inflict a defeat on the PR forces at this time and place. Two is greater than one. You can't make a dollar out of fifteen cents."

"At least we can gather some useful data from the situation, gentlemen. The Bolo Mark XX has been committed to battle. Its designers assure me that the new self-motivating circuitry will vastly enhance the combat-effectiveness of the Bolo. Let us observe."

Hate to see old Denny out there, just a great big sitting duck, all alone and-here they come! Look at 'em boiling out of there like ants out of a hot log. Can't hardly look at that screen, them tactical nukes popping fireworks all over the place. But old Denny know enough to get under cover. See that kind of glow all around him? All right, it, then. You know, working with him-it-so long, it got to feeling almost like he was somebody. Sure, I know, anyway, that's vaporized ablative shield you see. They're making it plenty hot for him. But he's fighting back. Them Hellbores is putting out, and they know it. Looks like they're concentrating on him now. Look at them tracers closing in on him! Come on, Denny, you ain't dumb. Get out of there fast.

"Certainly it's aware what's at stake! I've told you he-the machine, that is-has been fully programmed and is well aware not only of the tactical situation but of strategic and logistical considerations as well. Certainly it's an important item of equipment; its loss would be a serious blow to our present underequipped forces. You may rest assured that its pain circuits as well as its basic military competence will cause it to take the proper action. The fact that I originally opposed commissioning the device is not to be taken as implying any lack of confidence on my part in its combat-effectiveness. You may consider that my reputation is staked on the performance of the machine. It will act correctly."

It appears that the enemy is absorbing my barrage with little effect. More precisely, for each enemy unit destroyed by my fire 2.4 fresh units immediately move out to replace it. Thus it appears I am ineffective, while already my own shielding is suffering severe damage. Yet while I have offensive capability I must carry on as my commander would wish. The pain is very great now_f but thanks to my superb circuitry I am not disabled, though it has been necessary to withdraw my power from my external somatic sensors.

"I can assure you, gentlemen, insofar as simple logic functions are concerned, the Mark XX is perfectly capable of assessing the situation even as you and I, only better. Doubtless as soon as it senses that its position has grown totally untenable, it will retreat to the shelter of the rock ridge and retire under cover to a position from which it can return fire without taking the full force of the enemy's attack at point-blank range. It's been fully briefed on late developments, it knows this is a hopeless fight. There, you see? It's moving…"

"Thought you said-dammit, I know you said your pet machine had brains enough to know when to pull out! But look at it: half a billion plus of Concordiat funds being bombarded into radioactive rubbish. Like shooting fish in a barrel."

"Yes, sir, I'm monitoring everything. My test panel is tuned to it across the board. I'm getting continuous reading on all still-active circuits. Battle Reflex is still hot. Pain circuits close to overload, but he's still taking it. I don't know how much more he can take, sir; already way past Redline. Expected him to break off and get out before now."

"It's a simple matter of arithmetic; there is only one correct course of action in any given military situation. The big tactical computer was designed specifically to compare data and deduce that sole correct action. In this case my readout shows that the only thing the Mark XX could legitimately do at this point is just what the Professor here says: pull back to cover and continue its barrage. The onboard computing capability of the unit is as capable of reaching that conclusion, as is the big computer at HQ. So keep calm, gentlemen. It will withdraw at any moment, I assure you of that."
