What is the primary means of communication used during a patrol?

The primary means of communication used during a patrol is hand and arm signals. This method is essential for maintaining stealth and security, especially in situations where silence is crucial to prevent detection by enemy forces. Hand and arm signals allow soldiers to convey messages quickly and discreetly without the need for verbal communication, which can expose their location.

In the context of a patrol, visual signals are less likely to compromise the mission and can be understood at a distance even under adverse weather conditions or when ambient noise is high. Mastery of these signals is critical for effective teamwork and coordination within the squad, ensuring that all members are aware of commands and intentions without alerting adversaries.

While radio communications and verbal commands are useful in other contexts, they can attract attention and are not as efficient in maintaining the element of surprise during patrols. Written notes are not practical in dynamic situations where quick communication is necessary. Hence, hand and arm signals are the most appropriate and effective method for communicating on patrol.
