In which General Order is it stated that a sentry should not talk to anyone except in the line of duty?

The 7th General Order, which outlines the conduct of sentries, explicitly states that a sentry should not talk to anyone except in the line of duty. This emphasizes the importance of maintaining security and focus while on guard duty. By restricting communication to official interactions, the 7th General Order helps prevent distractions, potential breaches of security, and ensures that the sentry remains alert to their responsibilities. This is vital for maintaining the integrity of the duty they are performing, as any unnecessary conversation could lead to lapses in attention or information security.
