I wait, repeat my transmission; nothing. I am cut off from Command Unit, from my comrades of the Dinochrome Brigade. Within me, pressure builds.
I feel a deep-seated click and a small but reassuring surge of power brightens the murk of the cavern to a dim glow, burning forgotten components to feeble life. An emergency pile has come into action automatically.
I realize that I am experiencing a serious equipment failure. I will devote another few seconds to troubleshooting, repairing what I can. I do not understand what accident can have occurred to damage me thus. I cannot remember…
I go along the dead cells, testing.
"-out! Bring.09's to bear,.8 millisec burst, close armor…"
"… sun blanking visual; slide number-seven filter in place."
"… 478.09, 478.11, 478.13, Mark!…" The cells are intact. Each one holds its fragment of recorded sense impression. The trouble is farther back. I try a main reflex lead.
"… main combat circuit, discon-"
Here is something; a command, on the reflex level! I go back, tracing, tapping mnemonic cells at random, searching for some clue.
"-sembark. Units emergency standby…"
"… response one-oh-three; stimulus-response negative…"
"Check list complete, report negative…"
I go on, searching out damage. I find an open switch in my maintenance panel. It will not activate; a mechanical jamming. I must fuse it shut quickly. I pour in power, and the mind-cavern dims almost to blackness. Then there is contact, a flow of electrons, and the cavern snaps alive; lines, points pseudo-glowing. It is not the blazing glory of my full powers, but it will serve; I am awake again.
I observe the action of the unfolding arm. It is slow, uncoordinated, obviously automated. I dismiss it from direct attention; I have several seconds before it will be in offensive position, and there is work for me if I am to be ready. I fire sampling impulses at the black memory banks, determine statistically that 98.92% are intact, merely disassociated.
The threatening arm swings over slowly; I integrate its path, see that it will come to bear on my treads; I probe, find only a simple hydraulic ram. A primitive apparatus to launch against a Mark XXXI fighting unit, even without mnemonics.
Meanwhile, I am running a full check. Here is something… An open breaker, a disconnect used only during repairs. I think of the cell I tapped garlier, and suddenly its meaning springs into my mind. "Main combat circuit, disconnect…" Under low awareness, it had not registered. I throw in the switch with frantic haste. Suppose I had gone into combat with my fighting-reflex circuit open!
The arm reaches position and I move easily aside. I notice that a clatter accompanies my movement. The arm sits stupidly aimed at nothing, then turns. Its reaction time is pathetic. I set up a random evasion pattern, return my attention to my check, find another dark area. I probe, feel a curious vagueness. I am unable at first to identify the components involved, but I realize that it is here that my communication with Command is blocked. I break the connection to the tampered banks, abandoning any immediate hope of contact with Command.
There is nothing more I can do to ready myself. I have lost my general memory banks and my Command circuit, and my power supply is limited; but I am still a fighting Unit of the Dinochrome Brigade. I have my offensive power unimpaired, and my sensory equipment is operating adequately. I am ready.
Now another of the jointed arms swings into action, following my movements deliberately. I evade it and again I note a clatter as I move. I think of the order that sent me here; there is something strange about it. I activate my current-action memory stage, find the cell recording the moments preceding my entry into the metal-walled room.
Here is darkness, vague, indistinct, relieved suddenly by radiation on a narrow spectrum. There is an order, coming muffled from my command center. It originates in the sector I have blocked off. It is not from my Command Unit, not a legal command. I have been tricked by the Enemy. I tune back to earlier moments, but there is nothing. It is as though my existence began when the order was given. I scan back, back, spot-sampling at random, find only routine sense-impressions. I am about to drop the search when I encounter a sequence which arrests my attention.
I am parked on a ramp, among other Combat Units. A heavy rain is falling, and I see the water coursing down the corroded side of the Unit next to me. He is badly in need of maintenance. I note that his Command antennae are missing, and that a rusting metal object has been crudely welded to his hull in their place. I feel no alarm; I accept this as normal. I activate a motor train, move forward. I sense other Units moving out, silent. All are mutilated…
The bank ends; all else is burned. What has befallen us?
Suddenly there is a stimulus on an audio frequency. I tune quickly, locate the source as a porous spot high on the flint-steel wall.
"Combat Unit! Remain stationary!" It is an organically produced voice, but not that of my Commander. I ignore the false command. The Enemy will not trick me again. I sense the location of the leads to the speaker, the alloy of which they are composed; I bring a beam to bear. I focus it, following along the cable. There is a sudden yell from the speaker as the heat reaches the creature at the microphone. Thus I enjoy a moment of triumph.
I return my attention to the imbecile apparatus in the room.
A great engine, mounted on rails which run down the center of the room moves suddenly, sliding toward my position. I examine it, find that it mounts a turret equipped with high-speed cutting heads. I consider blasting it with a burst of high-energy particles, but in the same moment compute that this is not practical. I could inactivate myself as well as the cutting engine.
Now a cable snakes out in an undulating curve, and I move to avoid it, at the same time investigating its composition. It seems to be no more than a stranded wire rope. Impatiently I flick a tight beam at it, see it glow yellow, white, blue, then spatter in a shower of droplets. But that was an unwise gesture. I do not have the power to waste.
I move off, clear of the two foolish arms still maneuvering for position. I wish to watch the cutting engine. It stops as it comes abreast of me, and turns its turret in my direction. I wait.
A grappler moves out now on a rail overhead. It is a heavy claw of flint-steel. I have seen similar devices, somewhat smaller, mounted on special Combat Units. They can be very useful for amputating antennae, cutting treads, and the like. I do not attempt to cut the arm; I know that the energy drain would be too great. Instead I beam high-frequency sound at the mechanical joints. They heat quickly, glowing. The metal has a high coefficient of expansion, and the ball joints squeal, freeze. I pour in more heat, and weld a socket. I notice that twenty-eight seconds have now elapsed since the valve closed behind me. I am growing weary of my confinement.
Now the grappler swings above me, maneuvering awkwardly with its frozen joint. A blast of liquid air expelled under high pressure should be sufficient to disable the grappler permanently.
But I am again startled. No blast answers my impulse. I feel out the non-functioning unit, find raw, cut edges, crude welds. Hastily, I extend a scanner to examine my hull. I am stunned into immobility by what I see.
My hull, my proud hull of chrome-duralloy, is pitted, coated with a crumbling layer of dull black paint, bubbled by corrosion. My main emplacements gape, black, empty. Rusting protuberances mar the once-smooth contour of my fighting turret. Streaks run down from them, down to loose treads, unshod, bare plates exposed. Small wonder that I have been troubled by a clatter each time I moved.
But I cannot lie idle under attack. I no longer have my great ion-guns, my disruptors, my energy screens; but I have my fighting instinct.
