Steel armor is a protective covering made from steel, designed to shield individuals or vehicles from attacks. It is commonly used in military applications, such as on tanks and armored vehicles, to enhance their survivability in combat situations. The strength and durability of steel make it an effective material for resisting bullets, shrapnel, and other forms of weaponry. In addition to military use, steel armor can also be found in historical contexts, such as in the suits worn by knights during the Middle Ages. These suits, often referred to as plate armor, were crafted to protect the wearer in battle while allowing for mobility. Today, advancements in materials have led to the development of lighter and more flexible alternatives, but steel armor remains a significant part of military history.
