What is the primary function of arm and hand signals in fire control?

The primary function of arm and hand signals in fire control is to enhance communication in noisy environments. In combat situations, verbal communication can often be challenging due to the sounds of explosions, gunfire, and other battlefield noise. Hand and arm signals provide a reliable means of conveying commands and information between soldiers, enabling them to coordinate their actions effectively. This non-verbal form of communication ensures that important instructions regarding fire control, positioning, or maneuvers can be communicated quickly and clearly, regardless of the auditory distractions present.

Utilizing hand and arm signals is crucial for maintaining situational awareness and operational effectiveness in both direct combat and tactical movements, thereby facilitating teamwork and responsiveness among units.
