What is the primary purpose of using hand signals in the field?

The primary purpose of using hand signals in the field is to communicate silently and effectively without alerting the enemy. In combat situations, maintaining stealth is critical, as verbal communication can easily give away a unit's position. Hand signals allow soldiers to convey important information and instructions quickly and discreetly, which is crucial for maintaining operational security and the element of surprise.

While signaling for additional supplies, directing vehicle movements, or establishing communication with allied forces are important aspects of military operations, they do not encompass the fundamental need for stealth and quiet communication that hand signals fulfill in potentially hostile environments. This ability to communicate without noise helps ensure that movements and plans remain hidden from enemy observation, thereby enhancing the effectiveness of tactical maneuvers.
