Weapon
Robert Mason
 The novel describes a new weapon system being developed for the US military; the titular Solo. A robot, Solo is designed to replace human soldiers in battle. It is humanoid in shape, in order to allow it to use all the military vehicles and equipment human soldiers do. Solo is capable of feats of great speed, strength and endurance. Most importantly, Solo is governed by a neural network computer which is able to learn and think much as a human brain does. The robot's designer recognises that this could potentially make Solo as unpredictable and difficult to control as any human is; the military therefore insist that Solo be told a carefully edited version of world history and politics in which the United States are in all cases the unambiguously "good guys" and winners of all conflicts - for example Solo is told that the US won a clear victory in the Vietnam War. Despite his indoctrination, Solo begins to display what his designers consider aberrant behaviour. He begins to question and occasionally refuse his orders. For example on one training session Solo is assigned to shoot a human target in a sniper mission. He is told that the mission and target are real, and that he is to genuinely kill the person. He point blank refuses to do so. More worryingly to his designers, Solo is not entirely forthcoming about his reasons for such hesitancy. On another training mission Solo is lost; he is discovered by a group of Nicaraguan villagers who although initially fearful of him, come to trust the robot and depend on his protection. The novel details Solo's developing friendship with the villagers, whilst the US military attempts to recapture him.
