What is the primary duty of a sentry according to the 10th General Order?

The primary duty of a sentry according to the 10th General Order is centered around the importance of saluting. This order emphasizes the respect and protocol that must be shown towards officers, colors, and standards that are not cased. Saluting is a fundamental part of military courtesy, designed to maintain the hierarchy and mutual respect within the armed forces. By saluting all officers and colors, sentries help foster a dignified environment and uphold traditions that are essential to military culture.

While the other duties associated with a sentry—such as reporting unauthorized personnel, maintaining communication, and conducting inspections—are significant aspects of their responsibilities, the 10th General Order specifically highlights the act of saluting as a crucial duty. Thus, the focus on saluting in this context underscores the importance of respect and discipline within a military framework.
