Abstract

A marksmanship training system is disclosed as comprising a viewing screenpon which a scenic picture having a predetermined target included therein is projected by a combination motion picture projector and film. A plurality of simulated rifles shoot laser light shots of different colors, respectively, at the target located within the image of said projected motion picture scene. A like plurality of receiver channels respond to the colors of said laser shots respectively, and as a result of being properly synchronized with said projector and film, determine and indicate the number of target "hits" for any given number of shots. A color television camera and video tape recorder monitor training exercises, and a video tape player permits the playback thereof for additional training purposes. Optionally, a suitable sound system may be used in conjunction with the aforesaid projector and film combination, so as to provide a more realistic training environment for the marksmen while they are shooting at the aforementioned viewing screen with said simulated rifles.
