Abstract : Disclosed is a marksmanship trainer that can accommodate a plurality of trainees. The trainer includes the long range light pen that is the present invention to measure sighting accuracy and tracking steadiness. In the disclosure it is set with the sight of a simulated or operational weapon, and achieves resolution to the pixel level by using telescope optics and special purpose circuitry. Each trainee is provided with a raster scan display and a computer that provide a targe image and corrective feedback to the trainee. Bridge configured dual strain gauges are used to sense breathing, and a force sensing resistor is used to monitor trigger squeeze. Recoil is simulated mechanically, and a simulated report of the weapon is provided through a headset. The feedback of corrective action is provided aurally/graphically from a stored expert library.
