Guard

A guard is someone who supervises the protection and/or captivity of a person, item or location. In medieval lore, a guard was usually in service to an authoritative figure of noble bearing such as a King or a Duke. They protected the king's families and also managed castle dungeons.

Guards may also work in prisons where they are charged with maintaining order amongst the inmates, making sure that none of them try to escape.

Security guards are hired professionals that may work in various industries such as large companies, hospitals, or public centers.
