The practice of plotting artillery for future strike at a specific place is realistic, not gamey. The FOO makes sure his guns are sighted in, then they just wait for the order to fire.
There may have been a couple of ranging shots (depending on nation and era) that aren't seen in the game

The FOO can adjust this plot without having to stonk a target.
And as a player you pay the price of delay each time the target is adjusted.

You have also committed your guns to a target location where the enemy may not even appear.
