An artillery shell is a type of ammunition designed to be fired from large-caliber guns, such as howitzers or cannons. These shells are typically filled with explosives and can vary in size and type, including high-explosive, smoke, or illumination shells. They are used in military operations to deliver powerful strikes over long distances. When fired, an artillery shell travels through the air and detonates upon impact or at a predetermined altitude. The design of the shell allows for a range of effects, making it a versatile tool in warfare. Artillery shells play a crucial role in providing support for ground troops and targeting enemy positions.
