Which of the following is NOT part of the troop leading procedures in the defense?

The troop leading procedures in the defense are crucial actions that a leader must undertake to ensure their unit is prepared for combat operations. Establishing security, assigning sectors of fire, and coordinating with supporting units are all integral components of these procedures.

Establishing security involves setting up measures to protect the unit from enemy detection and initial attack. This is foundational in defense, as it allows for better control of the operating environment.

Assigning sectors of fire is essential for positioning unit members effectively, ensuring that all areas are covered and that there are no gaps in defense. This allows for effective cross-fire and maximizes the unit's defensive capabilities.

Coordinating with supporting units ensures that there are established lines of communication and cooperation between different military elements, allowing for a unified approach to defense.

In contrast, requesting reinforcements is not a part of the initial troop leading procedures but rather a subsequent action that may occur after the initial defensive setup. While it is certainly a critical aspect of broader operational planning and execution, it does not fall directly under the immediate troop leading procedures that a leader must conduct to prepare their unit for defense.
