SIMULATOR, WEAPON, FIRING AND RANGING (LASER) SYSTEM.

A Laser Weapon Simulator system--a device developed around a laser that simulates the important effects of a tankgun fired at a target, and accordingly enhances the training of tank gunners is described. In operation, this simulator is boresighted with the main tank gun. Aiming is achieved through the existing tank optics firing is accomplished by depressing the same trigger switch used in firing actual rounds. When the simulator is fired, the laser produces a concentrated red flash on the target which realistically simulates an actual round. Provisions are incorporated for the instructor to introduce deliberate offsets which must then be compensated by the trainee. The theory of operation of the laser plus optics, and the associated power supply, is presented in detail. Procedures for installing the simulator system on the tank and the target in the downrange area, for performing preoperation checkout, adjustment, and alignment, for conducting training exercises, and for troubleshooting and repairing the equipment, are also provided in detail. Safety precautions necessary in aligning, operating, and repairing the equipment are carefully noted. Author
