Shrapnel refers to fragments of a bomb, shell, or other explosive device that are propelled outward during an explosion. These pieces can cause injury or damage to people and objects in the vicinity. The term originated from Henry Shrapnel, a British Army officer who developed a type of artillery shell in the early 19th century designed to scatter small projectiles. Shrapnel can vary in size and shape, depending on the explosive device and its construction. It is often a significant concern in military conflicts, as it can lead to casualties even when the main explosive does not directly hit a target. Understanding shrapnel is important for safety and medical response in combat situations.
