Free The Complete Hammer's Slammers: Volume 3 by David Drake

pitched the bad chip out into mud and darkness. If she’d instead saved the fried unit, Daun would have examined it to determine the cause of failure. Long odds the problem was due to manufacturing error, but there was always a possibility that a short within the box was causing a hot spot.
    The chance to diagnose the underlying problem instead of merely fixing the symptom was much of the reason Daun had volunteered to climb the mast. Besides, he liked the hardware part of his work well enough that he preferred to be doing it instead of playing cards with strangers he couldn’t respect and didn’t much like.
    There were guy wires on each of the three sections of the telescoping mast. When he reached each set of guys, Daun unhooked one of his two safety loops, rehooked it above the wires, and repeated the process with the second loop. At no time did he trust merely his boots and grip to keep him on the mast. Daun wasn’t so much cautious as perfectly methodical. The notion of cutting corners to lessen his exposure to the chill drizzle didn’t cross his mind.
    Viewed from the top of the thirty-meter mast, the lights of Bulwark Base had a surreal innocence, like the gleam of will-o’-thewisps in a nighted meadow. Rain softened the patterns and dusted glare into sparkle. The scene wasn’t beautiful but it had a dignified tranquility, far removed from the muddy truth. The glowing canvas of the TOC could be the entrance to the Venusberg, and Daun could imagine that flashlights in the tents on the perimeter were cupids twinkling around the goddess of love.
    The receiving antenna at the mast peak was enclosed in a weatherproof capsule about the size of a soccer ball. The covering was dull gray plastic which was reasonably sturdy but remained transparent over most of the electromagnetic spectrum. Wherever possible, the sensor wands transmitted over microwave frequencies, but those without a line of sight to the receiver used VHF or UHF as circumstances required.
    Daun arranged the working canopy over the capsule. When he had it stiffened into position, the monomolecular sheeting blocked the rain completely. Before then, however, he managed to pour what felt like a liter of cold water down the back of his neck from the canopy’s folds.
    He sighed, clipped his light to a strut so that it shone down on the work, and opened the antenna capsule. Two of the micro-miniaturized circuits were black instead of the healthy gold color. That was neither surprising nor a problem. When one chip blew, it could easily have overloaded its neighbor. Daun’s repair kit contained at least three replacements for every chip on the chassis.
    He opened the cover wider as he prepared to pull the failed chips. An irregularity on the inner face of the cover caught his eye. The plastic had blistered and turned silvery on the side facing the chips that had failed.
    The antenna didn’t draw enough juice to heat the cover even slightly. A short circuit which blistered the plastic that way would have vaporized the circuitry, chassis and all, instead of popping a chip or two.
    The energy that had caused the antenna to fail had come from outside. The most likely outside source was a precisely aimed X-ray laser on one of the enemy-held hilltops overlooking Bulwark Base.
    Feeling colder than rain could make him, Daun reached up to key his commo helmet and alert the camp. The shock wave proved he was too late.
    The warhead went off with a hollow Klock! that blew one of the TOC trailers inside out in a sleet of aluminum. The weapon, a laser-guided anti-tank missile, was configured to defeat heavy armor with a shaped charge. A straight fragmentation or HE warhead would have been better suited for the present task. This was along the lines of killing mosquitoes with an elephant gun.
    On the other hand, an elephant gun will kill a mosquito. Little survived of the trailer, and nothing of anyone who happened to be in it.
    The canopy flapped skyward in the blast. The
