He opened his one remaining ration can, tore back the layers of thermofoil insulation, and started devouring the warm lamb stew. The dull staccato of automatic fire commenced far down the valley. Somebody screamed. Tom contemplated his own flashless weapon, trying to recall what he had been taught about its principle of expulsion. That had been so far back. A year? Two? He did not remember. It was time for the corporal to take over the watch, but Tom decided to give him another ten minutes. Wearily, he raised the binoculars to his eyes, pushed the switch. The battery was about exhausted and he replaced it. Overhead a flare was drifting downward, and he watched as it illuminated the murky battle ground. "Light up!" the platoon sergeant growled.
