The simple act of performing your duties in a military manner will keep you out of more trouble in your career than just about anything else. Drill these in your head and let them become second nature.
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 of 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. The Eleven General Orders are common to all branches of the U.S. Armed Forces. It is best to learn these before boot camp: you will be expected to know these by heart, in any order, after a few weeks in basic training!
1. To take charge of this post and all government property in view. 2. To walk my post in a military manner, keeping always on the alert, and observing everything that takes place within sight or hearing. 3. To report all violations of orders I am instructed to enforce. 4. To repeat all calls from posts more distant from the guard house than my own. 5. To quit my post only when properly relieved.
6. To receive, obey, and pass on to the sentry who relieves me all orders from the commanding officer, field officer of the day, officer of the day, and officers and petty officers of the watch. 7. To talk to no one except in line of duty.
8. To give the alarm in case of fire or disorder. 9. To call the petty officer of the watch in any case not covered by instructions. 10. To salute all officers and all colors and standards not cased. 11. To be especially watchful at night, and during the time for challenging, to challenge all persons on or near my post, and to allow no one to pass without proper authority.
