Free Resistance by William C. Dietz

Bullseye, and the remains of an encampment littered with partially gnawed human bones. All of which forced Hale to slow down lest he inadvertently walk into a Chimeran emplacement.
    By that time he knew he was nearing the White River. It ran roughly east and west, a few miles south of the main highway that ran between Rapid City and Sioux Falls. The Rocking F Ranch was located in the strip of land south of the highway and north of the river.
    In order to get there Hale would have to cross the river via one of the local bridges. The span he had in mind was a modest affair that had been put in place to serve ranchers who needed to move livestock back and forth across the waterway. Hale had spent the first two decades of his life in the area, so he knew exactly how to reach the bridge. But would it still be there? If so, was it being used by the Chimera? There was only one way to find out.
    At that point Hale decided to remove the clumsy snowshoes, bundle them with the ski poles, and tie all of them to his pack. Then, boots sinking into the snow, he fought his way up the side of a low-lying hill to an outcropping of rock at the top. A spot where a muchyounger Hale had spent many an hour while his horse grazed below. It was a fairly simple matter to circle around, find cover, and examine the bridge through his binoculars.
    The good news was that the structure was still in place, but the bad news was that four stinks were guarding it. Two of the Hybrids were stationed at the north end of the span, one carrying a Bullseye, and two of them paced back and forth at the south end, one of them wielding an Auger.
    The Chimera had smooth skulls, six eyes each, and mouths filled with needle-sharp teeth. None of the stinks were equipped with the sort of cool packs Hale had seen in England, suggesting that the cold weather was to their liking, and sufficient to keep their core temperatures down.
    This was a disappointment, since it had been Hale's hope to carry out his self-assigned mission entirely unnoticed. But he wasn't about to let four Hybrids prevent him from reaching his goal. So he shrugged off the pack, put the Rossmore aside, and brought the Fareye around to where he could use it. Then, placing his right glove on a rock, he set the rifle on top of it.
    With that accomplished, Hale brought his eye down to the telescopic sight and began the not altogether unpleasant process of deciding which stink to kill first.
    He needed to drop all four of the aliens one right after the other, if possible, both to clear a path across the bridge and to prevent them from spotting him before he had finished taking them down. Had the targets been human, Hale might have chosen to kill an officer or non-com first, but with no way to determine which freak was in charge, he had to rely on speed. So he made the decision to drop the sentries located at the north end of thebridge first, because they were farther away and had quicker access to cover.
    Then would come the ticklish task of swinging the Fareye to the right and acquiring his other two targets, both of whom would probably be firing on him by then. Thanks to the distance, he would retain the advantage, however, so he couldn't allow them to come closer. Because the last thing he wanted was for the alien with the Bullseye to tag him and send a dozen projectiles to seek him out. Or for the stink with the Auger to shoot
through
the rocks, and kill him that way.
    Judging from the drift of the snowflakes the wind was blowing west to east, something Hale would need to take into consideration along with the ambient air temperature and the way the slug would drop slightly while in flight. With all of those factors in mind, he placed the crosshairs over the first Chimera's head, made a tiny adjustment for the wind, and tilted the barrel up a fraction of an inch. Then, having taken a deep breath, he let most of it out. The trigger seemed to squeeze itself.
    The Fareye nudged Hale's shoulder, but thanks to the
