The primary focus of fire planning in the Block obstacle effect is to support obstacles effectively. This entails coordinating firepower in a way that enhances the obstacle's effectiveness in impeding or stopping enemy forces. The fire planning aims to create a synergistic effect where the firepower reinforces the physical barriers, ensuring that the obstacles serve their purpose in the overall tactical plan.

When obstacles such as barriers or mines are placed to restrict enemy movement, the simultaneous application of fire can prevent the enemy from breaching these obstacles and force them into kill zones where friendly forces can engage them more effectively. This coordination of fire and obstacles is vital for creating a defensive posture that can hold off or disrupt enemy advances.

In contrast, while maximizing psychological impact, preparing for breaching enemy lines, and ensuring rapid troop advancements are important tactical considerations, they do not specifically align with the primary goal of fire planning in the context of Block obstacles.
