Personal armour

Body armor or Body armour, or personal armor/armour is protective clothing, designed to absorb and/or deflect slashing, bludgeoning and penetrating attacks by weapons. It was historically used to protect military personnel, whereas today, it is also used to protect various types of police (riot police in particular), private citizens, private security guards or bodyguards. Today there are two main types: regular non-plated personal armor (used by the people mentioned above, except combat soldiers) and hard-plate reinforced personal armor, which is used by combat soldiers, police tactical units, private citizens, and hostage rescue teams.

Many factors have affected the development of personal armor throughout human history. Significant factors in the development of armor include the economic and technological necessities of armor production. For instance full plate armor first appeared in Medieval Europe when water-powered trip hammers made the formation of plates faster and cheaper. At times the development of armor has run parallel to the development of increasingly effective weaponry on the battlefield, with armorers seeking to create better protection without sacrificing mobility. With the development of capitalism and technological advancements armor became more available to the lower classes often at a cost of quality.

Eastern armor has a long history, spanning several thousand years, beginning in Ancient China. The oldest known Western armor is the Dendra panoply, dating from the Mycenaean Era around 1400 BC. Mail, also referred to as chainmail, is made of interlocking iron rings, which may be riveted or welded shut. It is believed to have been invented by Celtic people in Europe about 500 BC. Most cultures who used mail used the Celtic word Byrnne or a variant, suggesting the Celts as the originators. The Romans widely adopted mail as the lorica hamata, although they also made use of lorica segmentata and Lorica squamata. While no non-metallic armor survives, a linen laminate known as linothorax is repeatedly mentioned in ancient Greek sources.
