The Five Rings include: * Leadership * Organic/System Essentials/Key Production * Infrastructure * Population * Fielded Military Forces Each level of system or "ring" was considered one of the enemy's centers of gravity. The idea behind Warden's five rings was to attack each of the rings to paralyze their forces, an objective also known as physical paralysis. To optimize a strike attack the attacker would engage as many rings as possible with special emphasis on taking out the center ring, which is the enemy's leadership. This would result in total physical paralysis.
