What is the purpose of a strike in a defensive course of action?

A strike in a defensive course of action primarily aims to rapidly destroy key enemy organizations through mass precision fires. This tactic allows a defending force to disrupt the enemy's plans and capabilities, which is crucial for maintaining an effective defense. By targeting specific enemy units or installations with precise firepower, the defending side can weaken the overall offensive capabilities of the adversary, thereby providing relief and support to their own positions.

Implementing strikes effectively can change the tempo of the battlefield and inflict significant losses on the enemy, allowing the defending force to regain the initiative and provide a more robust defense against further attacks. This strategic element of striking is essential for turning the tide in defensive operations, as it can prevent the enemy from establishing momentum and effectively executing their own plans.

The other options, while they may have tactical relevance, do not encapsulate the primary purpose of a strike in a defensive context as accurately. Creating diversions, maintaining supply lines, and fortifying positions are all important components of a broader defensive strategy but do not directly relate to the striking capability aimed at inflicting significant damage on enemy forces.
