An anti-aircraft targeting computer. This allows a single man to use a regular rocket launcher or other long-distance weapon and hit airplanes with excellent accuracy. However, the skills involved in targeting land-based things, with speeds usually of below 100 mph, are much different from the skills involved in the air, where targets such as airplanes are moving hundreds of miles an hour. Terrain makes no difference in the latter; there is no terrain. Wind speed plays different roles in either one. So, in other words, a Anti-Aircraft Targeting Computer is not very good at targeting ground targets, and vice versa. Also, the AA Targeting Computer is expecting large, plane-sized targets, not human-sized targets. So a flying person such as Fred or a bird might go unassaulted due to the size.
