What should be established first in troop leading procedures for defense?

Establishing security is the first and foremost step in troop leading procedures for defense as it lays the foundation for the entire defensive operation. The primary concern when preparing a defensive position is to ensure that troops are protected from enemy observation and attack. By securing the area first, a leader can effectively control the movement of both their forces and the enemy, minimize vulnerabilities, and provide a safer environment for subsequent actions.

Establishing security encompasses various tasks, such as conducting reconnaissance to gather intelligence, positioning lookouts to keep watch for enemy movements, and setting up barriers or obstacles to delay or deter the enemy. These actions create a comprehensive security network, preventing surprise attacks and allowing for efficient communication and coordination amongst squad members.

Once security has been established, roles can be assigned to squad members, reconnaissance can be conducted for further intelligence gathering, and weapons can be calibrated with a clear understanding of potential threats and engagements. This progression ensures that all subsequent actions are taken with an informed and secure approach following the initial establishment of security.
