Which type of fire is aimed at targets behind enemy lines to support an attack?

The option indicating long range fires is correct because this type of fire is specifically designed to reach targets located beyond the immediate frontline and behind enemy lines. The primary purpose is to disrupt enemy positions, support maneuvering forces, and create a better operational environment for the attacking units. Long range fires enable forces to engage targets at a significant distance, allowing for the application of suppressive fire on enemy assets and infrastructure critical to their operations.

This capability is essential in modern combat scenarios where precision and reach are necessary to ensure that attacking forces can exploit vulnerabilities without exposing themselves to enemy fire. Such fires are typically executed by heavier artillery systems or advanced weaponry that is capable of engaging targets well beyond the direct engagement range of infantry weapons.
