The Lieutenant has lost several men to enemy snipers over the past several weeks. He orders the AWS to accompany one of the squads under his command and preemptively strike any enemy sniper nests it detects–again, an order he had given to other AWS units before without incident. This time, the AWS unit misidentifies a nearby civilian house as containing a sniper nest, based on the fact that houses with similar features had frequently been used as sniper nests in the Caucuses conflict. It launches a RPG at the house. There are no snipers inside, but there are 10 civilians–all of whom are killed by the RPG. Human soldiers who had been fighting in the area would have known that that particular house likely did not contain a sniper’s nest because the glare from the sun off a nearby glass building reduces visibility on that side of the street at the times of day that American soldiers typically patrol the area–a fact that the human soldiers knew well from prior combat in the area, but a variable that the AWS had not been programmed to take into consideration.
