Strategy without tactics is the slowest route to victory. Tactics without strategy is the noise before defeat.
Sun TzuThe control of large numbers is possible, and like unto that of small numbers, if we subdivide them.
Sun TzuHence that general is skilful in attack whose opponent does not know what to defend; and he is skilful in defense whose opponent does not know what to attack.
Sun TzuAgainst those skilled in attack, an enemy does not know where to defend; against the experts in defense, the enemy does not know where to attack.
