Which of the following is a critical responsibility of an infantry squad?

Executing tactical movements under fire is a critical responsibility of an infantry squad because infantry units are often required to maneuver in complex and dangerous environments where enemy engagement is likely. This responsibility involves coordinating actions to maintain combat effectiveness while responding to threats, which includes the ability to move quickly and efficiently to minimize casualties and maintain the initiative in battle. Effective tactical movement is essential for positioning the squad advantageously in relation to the enemy and for achieving mission objectives.

In combat situations, an infantry squad's ability to execute tactics while under fire not only enhances their survivability but also contributes to the overall mission success. Performing these movements requires a solid understanding of tactical principles, teamwork, and decision-making under pressure, all of which are vital components of infantry operations.
