"Not reallly a cheat - there is an artillery technique called a "silent barrage" where the guns are laid on various likely targets on a preplanned schedule as with a normal barrage, however no rounds are fired until the observer gives a keyword. The barrage then starts firing live rounds from that point."

Doesn't the game already account for this artillery practice in the deployment menu with preset artillery targets. IMHO reality= you can't be sure you will have rounds on target until you put rounds on target. But I was in the Infantry not the Artillery.
