Which of the following best describes a downside of ignoring signal communication training?

Ignoring signal communication training can lead to a heightened risk of operational failures, as effective communication is foundational for operational success in many environments. When personnel are not trained in signal communication, they may struggle with critical information exchange, leading to misunderstandings or misinterpretations. This can result in delays, coordination issues, and ultimately mission failure.

In military and operational contexts, where timely and accurate communication can be the difference between success and failure, neglecting this training can severely impact the effectiveness of operations. It can also lead to increased vulnerability to adversaries who exploit these communication gaps. Therefore, the significant risk associated with operational failures directly ties back to the lack of proper training in signal communication.
