What task/effect integrates direct and indirect fires to disrupt an enemy's formation?

The task that integrates direct and indirect fires to disrupt an enemy's formation is the one that specifically focuses on breaking the cohesion and effectiveness of the enemy's units. When an enemy's formation is disrupted, it lowers their ability to maintain effective communication, coordination, and combat strength, making them more vulnerable to additional actions by friendly forces.

Disruption entails not just inflicting casualties but also creating confusion and chaos within the enemy's ranks. This can be achieved through coordinated fire from both direct and indirect assets, which targets key elements of the enemy's setup, causing them to break formation and lose operational effectiveness. In contrast, the other terms such as divert, defeat, and deceive refer to different tactical objectives; divert shifts the enemy's focus, defeat implies total destruction or overwhelming of the enemy, and deceive involves misleading the enemy about one's own intentions or capabilities. Each of these has its role but does not specifically relate to the task of disrupting an enemy's formation.
