Noticed gunner still had to induce range. On M-1 Tank and I also believe the T-90 the ballistics computer induces lead of target based on distance and speed based on tracking of target.
Most of today s tanks have fire control systems that take into consideration, barometric pressure, temperature, barrel ware and barrel droop. and wind speed. It also has information placed in the computer for the lot of ammo based on test firing of that production ammo. Basically if all information for the ammo lot, and up to date barometric pressure information is feed to the computer it just requires lazing the target and keeping the reticle centered on the target. The computer automatically induces super elevation and lead.
