Upon a gunner's command, the gun is brought to the loading angle (+3° from horizontal), and the transporter starts to rotate, bringing the cassette with the desired type of round into the loading plane. The cassette then rises until its lower tier (main round) is in the ramming line. The loader then rams the round into the chamber of a gun fixed in a loading angle and then returns to its original position. The cassette lowers bringing the propellant charge to the ramming line, and it is rammed into the chamber in a second cycle. The cassette returns to its original position on a transporter, while the gun is automatically moved to the remembered engagement angle. After the shot the stub base is caught by the extraction mechanism and in the next loading cycle gets ejected out of the tank through the hatch in the rear of the turret.
