What is one of the key tasks of attack by fire?

One of the key tasks of attack by fire is to engage the enemy without direct contact. This approach allows military forces to inflict damage on the enemy and disrupt their operations while maintaining a safe distance, thus minimizing the risk to personnel. Utilizing indirect fire support, such as artillery or airstrikes, enables units to target enemy forces effectively and can be an essential tactic in various combat scenarios.

In contrast, other tasks mentioned, such as performing reconnaissance behind enemy lines, providing humanitarian aid, and establishing communication routes, do not specifically align with the primary objective of engaging the enemy through fire. These activities serve different operational purposes in military strategy, focusing either on gathering intelligence, supporting civil populations, or enhancing logistical capabilities, rather than direct engagement in combat.
