What type of fire supports artillery units in a combat operation?

In combat operations, artillery units primarily utilize indirect fire to support ground forces. Indirect fire refers to the targeting of enemy forces or positions that are not in the direct line of sight, allowing artillery units to engage threats from a distance using trajectories that can cover obstacles such as terrain or buildings. This method is essential for providing fire support while reducing the risk to friendly ground troops and increasing the effectiveness and range of artillery attacks.

While close air support, naval gunfire, and rocket artillery can also provide pivotal support in various situations, they represent different categories of firepower and operational support that may not directly pertain to the traditional role of artillery units like those operating the M119A3. Indirect fire specifically characterizes the core function of artillery as it effectively complements the infantry's maneuvers by creating suppressive fire that disrupts enemy actions and provides opportunities for tactical advancement.
