A suit of armour, also known as a suit of armor or full plate armour, is a type of protective clothing worn by soldiers in battle. There are several synonyms for the term, including panoply, harness, plate mail, and full suit. Other terms like armour suit, chainmail suit, and knight's armour are also used. The history of armour dates back to ancient times, with different types of armour used in different parts of the world. Today, suits of armour are no longer used for protection but are often displayed in museums or used for reenactments of historical battles.
