Which is NOT one of the six purposes of offensive combat?

The statement that "Gain tactical advantages" is not one of the six purposes of offensive combat is incorrect because gaining tactical advantages is a fundamental goal of any offensive action. When forces engage in offensive operations, they aim to not only disrupt the enemy’s actions and deceive or divert them but also to position themselves advantageously in the combat space.

The three purposes of offensive combat generally include disrupting enemy actions, deceiving or diverting the enemy, and maintaining a constant pressure to minimize their capabilities. While "Defense of resources" is crucial for overall military strategy, it does not fall under the specific purposes of offensive combat which are focused on proactive measures against an opponent. Gaining tactical advantages ensures that the attacking force can execute their operations effectively and maneuver in a way that maximizes their potential for success.
