I think there's a meaningful difference here, and it's very incorrect to consider it an incremental change.
An infantry squad dug into foxholes in some forest in WWII was really quite safe against artillery. A forward observer can maybe spot a tank or artillery battery (sometimes). A drone can scan an entire battlefield and identify infantry 10 miles behind a line of trenches, and coordinated artillery strikes can wipe them out.
That's hugely difference! It vastly changes the lethality per unit of artillery, and the relative risk for infantry units who aren't in obviously-fortified positions.
