What is the function of the police whistle in rendering honors?

The function of the police whistle in rendering honors primarily serves to indicate the start and conclusion of a salute. When honors are to be rendered, such as during the arrival or departure of a senior officer, the whistle provides a clear and audible signal for personnel to initiate or conclude the salute. This ensures that all crew members are synchronized in their actions, maintaining discipline and protocol during these formalities.

The use of a whistle in this context helps to eliminate confusion and enhances the formality of the honors by providing a definitive and consistent signal. This clear auditory cue reinforces the importance of the occasion and helps uphold the traditions of military protocol.
