Russian military personnel began to use the SLIB-177 laser complex in exercises. The SLIB-177 laser combat simulation system is designed for training and tactical training of soldiers. In simple terms, a soldier is wearing a vest with laser sensors, and the weapon is equipped with an Aspid laser designator combined with a trigger. During the exercise, the system analyzes whether the soldier was hit and in what area. The SLIB-177 complex is quite complex and operates on microcomputers. The operating time of the complex is 10 hours, the range of use is up to 800 meters. In a more complex version, the soldier's vest can be equipped with electroshock devices to simulate a hit.
