When summoning subordinate leaders, what signal should be used?

Raising one hand in a fist is an effective and widely recognized signal for summoning subordinate leaders because it draws attention in a clear and commanding manner. This gesture stands out and can be quickly recognized even in chaotic or noisy environments, making it a practical choice in operational settings. It conveys authority and indicates a need for immediate attention without causing confusion about intent, as it is distinct from other casual gestures.

Using this signal aligns with standard military communication protocols, ensuring that subordinate leaders understand the urgency or significance of the request. It avoids the potential ambiguity that could arise from other options, which might not be as universally understood or might be interpreted in various ways, especially in high-stress situations.
