What does TC 3-21.6 cover?

TC 3-21.6 focuses specifically on visual signals, which includes hand and arm signals used for communication during aviation operations. These signals are essential because they provide a non-verbal way for personnel to communicate in environments where radio communication may not be feasible or could be disrupted. The training outlined in TC 3-21.6 emphasizes the importance of these signals for safety and coordination, especially in air assault missions where swift and clear communication can be crucial. Understanding and utilizing these signals correctly is vital for personnel involved in air assault operations to ensure effective teamwork and to avoid miscommunication during critical missions.
