Armor design involves creating protective gear for individuals, primarily in military or combat situations. The design process considers materials, weight, and mobility to ensure that the armor can effectively shield the wearer from various threats, such as bullets or sharp objects. Common materials used include metals, ceramics, and advanced composites, each chosen for their specific protective qualities. Throughout history, armor has evolved significantly, from the heavy plate armor of the Middle Ages to modern tactical vests used by military personnel. Designers must balance protection with comfort and agility, allowing wearers to move freely while remaining safe in dangerous environments.
