Which of the following is NOT a technique for demonstrating noise discipline?

• A. Avoid unnecessary vehicular and foot movement.
• B. Secure metal parts to prevent noise.
• C. Shout operational orders to ensure clarity.
• D. Use radios only when necessary and keep the volume low.

Answer: (C)

Noise discipline focuses on keeping audible signals to a minimum so you remain discreet and your position isn’t revealed. Shouting operational orders directly increases noise and can be heard by others, potentially giving away where you are and causing confusion among the team. That behavior runs counter to the goal of staying stealthy and maintaining clear covert coordination.

By contrast, the other practices support quiet operations: avoiding unnecessary vehicle and foot movement reduces step and engine noise; securing metal parts prevents clanking and jingling; and using radios only when necessary with the volume kept low minimizes radio chatter that could be picked up by observers. When communication is needed, rely on quiet, pre-arranged hand signals or concise, low-volume transmissions to preserve silence and situational awareness.
