The Copperhead’s guidance vanes that maneuvers the round onto target are clearly visible in this silhouette image before impact. As long as the howitzer fires in the general direction of the target, the guidance systems can steer the round during its ballistic trajectory to the illuminated point. The round’s “footprint” is determined by the range, direction, and parabola of the firing ballistics. The footprint determines the probability of the round hitting the illuminated target. The smaller the footprint, the more likely the round is to land on target.
