In the faint green light from the panel, the dead man crouched over the controls, one desiccated hand in a shriveled black glove clutching the control bar. He wore a GI weather suit and a white crash helmet, and one foot was twisted nearly backward, caught behind a jack lever. The leg had been broken before he died. He must have jammed the foot and twisted it so that the pain would hold off the sleep that had come at last. I leaned forward to see the face. The blackened and mummified features showed only the familiar anonymity of death, but the bushy reddish mustache was enough. "Hello, Mac," I said. "Sorry to keep you waiting; I got held up." I wedged myself into the co-pilot's seat, flipped the IR screen switch. The eight-inch panel glowed, showed me the enemy Bolo trampling through the fence three hundred yards away, then moving onto the ramp, dragging a length of rusty chain-link like a bridal train behind it. I put my hand on the control bar. "I'll take it now, Mac." I moved the bar, and the dead man's hand moved with it. "Okay, Mac," I said. "We'll do it together." * * * * * I hit the switches, canceling the pre-set response pattern. It had done its job for eighty years, but now it was time to crank in a little human strategy. My Bolo rocked slightly under a hit and I heard the tread shields drop down. The chair bucked under me as Mallon moved in, pouring in the fire. Beside me, Mac nodded patiently. It was old stuff to him. I watched the tracers on the screen. Hosing me down with contact exploders probably gave Mallon a lot of satisfaction, but it couldn't hurt me. It would be a different story when he tired of the game and tried the heavy stuff. I threw in the drive, backed rapidly. Mallon's tracers followed for a few yards, then cut off abruptly. I pivoted, flipped on my polyarcs, raced for the position I had selected across the field, then swung to face Mallon as he moved toward me. It had been a long time since he had handled the controls of a Bolo; he was rusty, relying on his automatics. I had no heavy rifles, but my pop-guns were okay. I homed my 4 mm solid-slug cannon on Mallon's polyarc, pressed the FIRE button. There was a scream from the high-velocity-feed magazine. The blue-white light flared and went out. The Bolo's defenses could handle anything short of an H-bomb, pick a missile out of the stratosphere fifty miles away, devastate a county with one round from its mortars--but my BB gun at point-blank range had poked out its eye. I switched everything off and sat silent, waiting. Mallon had come to a dead stop. I could picture him staring at the dark screens, slapping levers and cursing. He would be confused, wondering what had happened. With his lights gone, he'd be on radar now--not very sensitive at this range, not too conscious of detail.... I watched my panel. An amber warning light winked. Mallon's radar was locked on me.
