A universal weapon fire simulation system in which frames of motion picture ilm are employed to produce simultaneously from one set of frames a background area including a target and, from another set of frames, an infrared lead aim spot. The sets of film frames are coordinated in projection in a desired degree of non-registration between the lead spot and the target to provide a lead in the infrared spot representative of the correct lead and elevation of a properly aimed weapon. The invention also includes a receiver circuit comprising a quadrant arrangement of infrared detectors for sensing the infrared lead aim spot when the weapon is correctly aimed, and amplifier, comparator, logic and hit indicator means for indicating a miss, hit, or a specific area of near miss when the weapon is triggered to activate the sensor circuit.
