Which of the following is NOT considered a basic task of fire support?

The task of establishing local supply routes is typically not classified as a basic task of fire support. Fire support primarily focuses on delivering effective fire to support troops engaged in combat, which includes tasks like supporting forces in contact, sustaining fire support operations, and synchronizing fire support to coordinate the use of different fire assets.

Support forces in contact involves providing direct fire assistance to troops that are actively engaged with the enemy, ensuring that they have the necessary firepower to maintain their position or achieve objectives. This is a vital function of fire support.

Sustain fire support operations refers to the ongoing management and provision of fire support, ensuring that units have adequate ammunition, coordination, and resources to continue operations effectively.

Synchronizing fire support involves coordinating various fire assets (such as artillery, air support, and naval gunfire) to optimize their impact on the battlefield. This ensures that fires are delivered in a timely and effective manner, reducing the risk of friendly fire and maximizing support for maneuvering forces.

In contrast, establishing local supply routes is more aligned with logistics than fire support operations. While logistics is essential for overall success in military operations, it does not fall under the category of basic fire support tasks. Hence, this option stands apart from the fundamental responsibilities of fire support.
