How should Number 2 communicate the need to repeat the deflection?

The correct choice for communicating the need to repeat the deflection emphasizes a concise and standardized form of communication that is essential in a military context, particularly when coordinating in a high-stakes environment like artillery operations.

By stating, "Deflection, number 2," Number 2 clearly identifies the task at hand (horizontal aiming direction) followed by the specific call sign or position that requires attention. This method adheres to the principles of effective military communication by being direct and immediate, reducing the potential for confusion in a dynamic situation. Using a succinct format helps ensure that commands and requests are understood quickly and accurately, which is crucial for operational efficiency and coordination among team members.

This style of communication aligns with standardized Army protocols, which prioritize clarity and brevity in commands, particularly in artillery operations where timely and accurate responses can significantly impact the mission's success.
