For the French I know some real life facts about counter battery:
Artillery officer Jean du Teil published a treatise on the use of artillery in 1778, which greatly influenced Napoleon, since he served with du Teil in the same artillery regiment under Jean du Teil's older brother Joseph, who became one of Napoleons chief patrons.
French Artillery was made shorter, therefore lighter and therefore better to handle when General Gribeauval was inspector general of the french artillery. With those improvements du Teil's opinion was that artillery should be more agressively used than before. When casualties occured, a fresh battery should come forward as fast as possible, to relieve the weakened unit and keep the firepower up.
Another thing du Teil's reforms brought, and this is why I started to write here in the first place
, is that he argued against counter battery fire. In his opinion it was a waste of resources and fire should instead be concentrated primarily on enemy troops and only fire on artillery when there was no other target, or the enemy artillery was causing too much trouble.
So for the french, I think we can say, counter battery fire in real life was not the primary use of artillery, like in other armies.
