The Israeli Armor Corps is a corps of the Israel Defense Forces, since 1998 subordinate to GOC Army Headquarters. The Armor Corps is the principal maneuvering corps, and primarily bases its strength on Main Battle Tanks. The Armor Corps is the decisive corps in GOC Army Headquarters, and bases its "crushing power" on its "fists of steel": a combination of mobility, armor, and firepower. During wars, its role is, on the one hand, to lead the first line of the attacking forces and to clear the area of the enemy, while on the other hand, to block the armor forces of the enemy and to destroy its tanks and armor. During peacetime, it reinforces the Infantry Corps while it performs security tasks, with the tanks serving as a mobile bunker.
