helm

A helmet is a protective covering for the head, serving as a universal form of armor. While commonly associated with military use, helmets are also essential for firefighters, miners, construction workers, police, motorcyclists, athletes, and bicyclists.

Historically, helmets protected the head, face, and neck from weapons like swords, spears, and arrows. Ancient civilizations such as the Assyrians, Persians, Greeks, and Romans developed sophisticated helmet designs using materials like leather, iron, bronze, and steel. These designs evolved over centuries, with innovations like movable visors and rounded contours to deflect blows.

The steel helmet re-emerged as standard infantry equipment during World War I to protect against artillery shell fragments. Modern infantry helmets are typically smooth, rounded hemispheres made of hardened steel, weighing between 1 to 4 pounds. Helmets are also significant in heraldry, where their depiction can indicate rank, and in non-Western cultures, where they are often valued as works of art.12
