Armor

v. cover with armor

n. hard protective covering for the body; covering of metal plates (on warships, tanks, etc.)

Armour or armor (see spelling differences) is protective clothing intended to defend its wearer from intentional harm in combat and military engagements, typically associated with soldiers. Armour has been used throughout recorded history, beginning with hides, leather, and bone, before progressing to bronze, then steel during the Roman Era, to modern fabrics such as Kevlar, Dyneema and ceramics.

The defense of the knight against the weapons of his opponents, consisting of his complete harness . Often this was used only to denote the "hard" bits of the harness, the hardened leather or plate defenses, rather than the softer arming garments, though sometimes layered cloth was also used as the sole defense, as in a jupon . I use the English spelling with the "-our" rather than the Americanized version to denote the difference between modern armored combat vehicles (e.g. tanks) and armour that is meant for the individual medieval soldier.
