Gun sights: lead, dumping lead, and delta-D

In Gunner, HEAT, PC!, fire control systems (FCS) often include automatic lead adjustment for moving targets. "Lead" refers to the horizontal aim shift needed to account for a moving target's position when the shot reaches it. In GHPC, some vehicles, like the M60A3 TTS, apply lead automatically when lasing. This feature adjusts for the last 1.5 seconds of aim movement.
To cancel a lead offset, "dump" the lead using Ctrl + E or the quick menu (Q). Additional FCS features are accessible through the quick menu.
Delta-D, another FCS feature, automatically adjusts range as the vehicle moves towards or away from the aim point. It activates after lasing and can be canceled using the same shortcut as dumping lead. The T-72M1 is an example of a vehicle with this feature.
