A shield is a piece of metal or another durable material designed to safeguard the front of the body during attacks. It serves as a vital defensive tool in various scenarios where protection from physical harm is necessary.

In law enforcement, riot shields are commonly used by police officers to protect themselves from projectiles, blows, and other forms of assault during demonstrations or confrontations with hostile crowds. These shields are robust and often equipped with additional features like visors for facial protection.

Beyond its literal meaning, the term "shield" can also refer metaphorically to a person or thing that provides protection. This extended usage highlights the concept of safeguarding against potential threats or dangers.

For instance, the ozone layer in the Earth's atmosphere acts as a natural shield against harmful radiation from the sun. It absorbs ultraviolet radiation, thereby reducing the risk of skin cancer and other health issues related to overexposure to these rays.
