What is the primary purpose of smoke rounds in artillery operations?

The primary purpose of smoke rounds in artillery operations is to obscure visibility for enemy forces. When smoke rounds are deployed, they create a dense cloud that significantly reduces the ability of the enemy to see and accurately target friendly units. This tactical advantage can be crucial during offensive maneuvers or when repositioning forces, as it helps to conceal movements, protect troops, and hinder the enemy's situational awareness. By effectively using smoke, military units can create cover, allowing them to execute strategies with more safety and effectiveness.
