Orders to Sentry is the official title of a set of rules governing sentry duty in the United States Armed Forces. While any guard posting has rules that may go without saying, these orders are carefully detailed and particularly stressed in the U.S. Navy, U.S. Marine Corps, and U.S. Coast Guard. Also known as the 11 General Orders, the list is meant to cover any possible scenario a sentry might encounter on duty. All recruits learn these orders verbatim while at recruit training and are expected to retain the knowledge to use for the remainder of their military careers. It is very common for a drill instructor or an inspecting officer to ask a question such as, "What is your sixth general order?" and expect an immediate reply.

U.S. Army
The U.S. Army now uses a condensed form of orders, with three basic instructions. Previously it used the same eleven general orders as the U.S. Navy and U.S. Marines.
I will guard everything within the limits of my post and quit my post only when properly relieved.
I will obey my special orders and perform all my duties in a military manner.
I will report violations of my special orders, emergencies, and anything not covered in my instructions to the commander of the relief.
