Upon returning to friendly lines and leaving the squad in a covered position, who moves forward to make contact with the forward unit?

The choice of the security team to move forward to make contact with the forward unit is grounded in the tactical principles of maintaining security and effective communication in a patrolling scenario. The security team is specifically tasked with ensuring that the area is clear of threats, providing a safe environment for the rest of the patrol and the command elements.

By deploying the security team to make contact with the forward unit, the squad can reduce the risk of ambush or surprise from the enemy. The security team's role includes conducting reconnaissance, assessing potential threats, and facilitating a secure line of communication with the forward unit. This is essential in military operations, where situational awareness and rapid information exchange are critical for the effectiveness of the larger unit.

The assistant patrol leader typically supports the patrol leader in planning and executing the patrol, while the SAW gunner focuses on providing suppressive fire if needed. The navigator's role is primarily to ensure the unit remains oriented and on the correct route. While all these roles are important, they are not primarily designed to engage directly with other units, especially in scenarios where security and reconnaissance are a priority. Thus, the selection of the security team for this particular task aligns with the standard operational practices in infantry patrolling.
