Armour (spelled armor in the United States of America) is a protective covering that is used to prevent damage from being inflicted to an object, individual, or vehicle by direct contact weapons or projectiles, usually during combat, or from damage caused by a potentially dangerous environment or action (e.g., cycling, construction sites, etc.). Personal armour is used to protect soldiers and war animals. Vehicle armour is used on warships and armoured fighting vehicles.
