The First General Order of the Guard is "To take charge of this post and all government property in view." This order is foundational for the role of a sentry or guard, establishing the primary responsibility of ensuring the security and protection of a designated area and any property within their line of sight. The essence of this order emphasizes accountability and vigilance, which are critical qualities for anyone in a guard position, reinforcing an understanding that the guard is entrusted with both a location and the assets it contains.

The other options describe important but secondary responsibilities. Walking the post in a military manner relates to the conduct expected while on duty but does not capture the primary duty of overseeing the post and property. Reporting violations and repeating distant calls are also significant tasks, but they are part of the broader responsibilities that come after the fundamental duty of taking charge is established. Thus, the emphasis on charge and protection in the correct answer highlights the sentinel's essential role in maintaining security.
