ข้อมูลระบบกล้องเล็ง PNK-6 ,1G46M และ PTT-2 ที่ติดตั้งอยู่ในรถถังหลัก OPLOT..
- detection and identification of ground and aerial targets by the tank commander in daylight and at night;
- target range measurement by a laser rangefinder;
- target designation for the gunner;
- targets engagement with the gun and coaxial machine-gun by the commander in the backup or semiautomatic autonomous backup control mode (in case of the gunner's fire control system failure);
- ATGM fire in the backup mode using the gunner's TI channel. The sight is used in the "OPLOT" tank fire control system and can also be used to upgrade the T-64B, T-72 and T-80 tanks

PTT-2 is used by the gunner and commanderto observe, detect, identify and engage targets with the gun and coaxial machine-gun by day, night and under adverse weather conditions. It is used in the fire control systems of the T-80, T-84 and "Oplot" tanks. The PTT-2 system can also be used to upgrade the T-72, T-64B, T-55, and T-62 tanks. The sight is operated with a ballistic computer and laser rangefinder
