What is the purpose of a demonstration in military operations?

A demonstration in military operations primarily serves the purpose of distracting the enemy's attention. By conducting a demonstration, forces can create the appearance of an imminent and significant action in one area, effectively drawing the attention and resources of the enemy away from other areas where a real offensive may occur. This tactic allows for deception and can lead to an opportunity for a more decisive action elsewhere.

While elements such as probing enemy defenses or securing supplies can be parts of military strategy, they do not encapsulate the primary intent of a demonstration. A demonstration's main focus is on creating a diversion rather than direct engagement or logistical objectives, which makes distracting the enemy's attention the most accurate answer regarding the purpose of a demonstration.
