What I’m suggesting is that if you have several of the same type of artillery pieces in close proximity to one another then you should have the ability to do adjusting fire with just one piece (to save ammo and be less conspicuous about your intentions) and then propagate the accuracy increase to the rest of the pieces in the battery.
Accuracy? You mean line of sight?
Not line of sight. There’s code in place which increases the accuracy of artillery after a few shots if there’s a unit providing LOS where the shells land. Currently each artillery piece must perform this process individually, my suggestion was that only one piece per battery do this process and then the whole battery fires with increased accuracy.
