Between the American Civil War and World War II, the number of artillery pieces deployed by military units increased dramatically, reflecting a broader trend of rising firepower and industrial-scale warfare.1

This growth in quantity is illustrated by the changing composition of infantry divisions:
* American Civil War: An infantry division of 3,000 to 5,000 men typically had an artillery complement of up to 24 pieces.1
* World War II: A comparable infantry division of approximately 15,000 men was equipped with 328 artillery pieces.1
* Armoured Divisions: By World War II, specialized armoured divisions were equipped with nearly 1,000 pieces of artillery.1

This quantitative expansion was accompanied by significant technological advancements, such as the introduction of recoil-control systems, which allowed for much more rapid fire. The scale of production also shifted from the limited industrial output of the 1860s to the massive mobilization of the 20th century, where millions of tons of steel were dedicated to manufacturing artillery and ammunition to sustain prolonged, large-scale operations.231
