The rule that tells a sentry to talk to no one except in the line of duty is about keeping communication purposeful and the guard’s attention focused. By limiting speech, it reduces distractions, prevents casual chatter from revealing information, and ensures any necessary communication is official and clear to the right people. This helps the sentry stay alert to sounds, movements, and signals and ready to respond to threats or instructions. Other orders cover duties like posting, relief, reporting violations, or emergencies, but this particular directive is specifically about maintaining silence while on guard to preserve security and discipline.
