The 2S19's gun crew can load the gun at any angle of elevation. Ammunition and gun loading, laying and re-targeting are highly automated, allowing maximum firing rate of 8 rounds per minute with onboard rounds and 6-7 rounds per minute with rounds from the ground. The system provides automatic gun loading for projectiles and semi-automatic loading for charges.
