If your enemy is secure at all points, be prepared for him. If he is in superior strength, evade him. If your opponent is tempermental, seek to irritate him. Pretend to be weak, that he may grow arrogant. If he is taking his ease, give him no rest. If his forces are united, separate them. If sovereign and subject are in accord, put division between them. Attack him where he is unprepared, appear where you are not expected.

(Mission/task Verb) A tactical task or obstacle effect (that integrates fire planning and obstacle effort) that breaks apart an enemy's formation and tempo, interrupts the enemy's time table, causes premature commitment of forces, and/or splinters their attack.
