This training simulator is designed for both individual and group training with sniper rifles as well as other types of light firearms without using ammunition as well as to sustain the acquired sniper skills on a required high level. The training simulator supports shooting practice against stationary, mobile, close proximity, remote and very remote targets. The shots are emulated by sending a laser pulse along the target line that is accompanied by the sound in n the shooter's headphones. The training simulator is equipped with a computer and a high resolution TV camera, which registers the hit point of the laser beams on the targets, the optical axis of the TV camera and the projector are aligned with high precision. The performance results of the shooters are displayed in symbolic and digital formats on the individual computer screens in real time. The training simulator includes a trigger emulator and an autonomous emitter device the simulator that allow training with real firearms that are free of ammunition.
