Abstract: An electro-optical apparatus for marksmanship training wherein a simulated cene is presented on a screen by a motion picture projector. The marksman or trainee operates a weapon, which includes a module to develop a laser beam, to simulate firing at a target on the scene. The apparatus provides an improved optical system including a dichroic mirror which permits the light which projects the target scene to pass through the mirror for providing an improved scene illumination while reflecting substantially all the laser beam energy to activate a target hit detector.
