Abstract : This patent discloses a trainer for manually aimed weapons, having a projection screen video system, a video disk player for providing pre-recorded scenes of a target image, a simulated weapon having actuable trigger, and a microprocessor having a file that identifies target location and range within each frame of the scenes and programmed to superimpose upon actuation of the trigger a graphic in-flight and impact image of a shot computed from a fourth order ballistics equation. Recoil of the simulated weapon is provided by pneumatics, as well as sound effects of the shot and its distant impact. Hit and miss explosions are provided in graphics selected from a set of stored image data by comparing the computed location of impact to the pre-identified target location. For shots that impact beyond the target, blanking of the graphics image is provided for that part of the explosion hidden by the target.
