Artillery shells are large projectiles designed to be fired from artillery pieces, such as howitzers and cannons. They come in various types, including high-explosive, smoke, and illumination shells, each serving different tactical purposes on the battlefield. The design and construction of these shells are crucial for their effectiveness and safety during use. When fired, artillery shells can travel long distances and deliver devastating impacts on enemy positions. The technology behind artillery shells has evolved significantly over the years, incorporating advanced materials and guidance systems to improve accuracy and lethality. Understanding their mechanics is essential for military strategy and operations.
