"Did you hear the rumor," Hank went on, "that every guy going into combat has something done to him so he'll kill himself if he's captured? Hypnotism or something?" "Uh-huh." Murphy wished Hank hadn't mentioned that. He remembered, there at Fort Hendricks, something strange had happened. Take a battalion of men, line them up outside a hospital. One by one, as the men enter a room, give them an injection that knocks them cold. Keep them unconscious for days while you feed them through the veins, and then revive them, put them in a formation and march them back to their barracks without an explanation. Do something like that and you'll cause all sorts of rumors. Those men will wonder what happened to them while they were unconscious. The more they wonder, the more fantastic the rumors will get.... "I doubt it," Murphy said. They had been whispering. No enemy followed a barrage so close that they were killed by their own shells, and Antarians could only move at a certain speed. That always left—immediately after a barrage—a few minutes during which they could talk or whisper in safety. But that time was limited and they fell silent now. Murphy thought, Somewhere out there, lizard-like things are crawling toward us. Any minute now, they'll be close enough to hear us if we make a sound, and they'll be waiting, hoping to hear a sound. They'll be holding their weapons with their tentacles as they move closer. They should be in a zoo where you could see them on Sunday afternoons and laugh. They're funny-looking, but it's hard to laugh at them while they're trying to kill you— A rumble of sound. Murphy swung his rifle, aiming through the sights. It was a tank. They had no hand grenades, and it was impossible to knock one out with a rifle. But, he reminded himself, he had explained to Hank. It was a soldier's job to fight, even with rocks if necessary. No. It was one of their tanks! "Let's go! Maybe they'll give us a ride!" They climbed out of the foxhole. Murphy ran toward the tank, raising his arms above his head—not a gesture of surrender, but a means of recognition. Antarians could walk on their hind legs but their physiology did not allow them to raise their forelegs above their heads as men could. At night, when nothing could be seen clearly, it was the most effective password. The tank stopped.
