What is a common signal for starting and stopping live fire training exercises?

The designated audible signal, such as a horn or whistle, is commonly used to start and stop live fire training exercises because it provides a clear and immediate notification that can be heard by all participants, regardless of their location within the training area. This method is particularly effective in ensuring that everyone engaged in the training is aware of the action at the same time, reducing the risks associated with miscommunication or confusion.

Audible signals are essential for maintaining safety and coordination in live fire environments, as they can cut through background noise and be recognized by all individuals involved, facilitating a swift response. Other methods, while they may have their applications, do not offer the same level of clarity and immediacy needed in high-stakes situations, making the audible signal the preferred choice.
