Armour, commonly called armor, is a covering that is used to protect an object, individual, or a vehicle from direct contact weapons or projectiles, usually during combat, or from a dangerous environment or action (e.g., cycling, construction sites, etc.).Personal armor is used to protect soldiers and such war animals as war horses (the application for the latter called barding). Vehicle armor is used on warships and armored fighting vehicles.
The word “armour” was introduced into use in the Middle Ages as a borrowing from the French. It is dated from 1297, as a “mail, defensive covering worn in combat” from Old French armoire, itself derived from the Latin armatura “arms and/or equipment” with the root arma “arms or gear”.
Throughout recorded history armor has been made from various materials: from rudimentary leather protection, personal armor evolved to Mail and full plated suits of armor. For much of military history the manufacture of metal personal armor has dominated the technology and employment of armor, which drove the development of many important technologies of the Ancient World, including wood lamination, mining, metal refining, vehicle manufacture, leather processing, and later decorative metal working. Its production influenced the industrial revolution and commercial development of metallurgy and engineering. Armor most influenced the development of firearms, which revolutionized warfare.
