 I'm going to go walk and we're going to change. I'll see you in inspection, but I'll be right back. The Tomb of the Unknown Soldier is a monument that has three unknown soldiers through respective wars. And the guards out there, they guard this monument 24 hours a day, 365 days a year. To become a sentinel, there are several requirements that have to be met, although we only grade in three different areas, such as the uniform, the outside performance, and their knowledge. So long, my comrades. Sleepy, hello. Since the badge was first awarded in 1958, in about 60 years, in that 60-year period, we've only had 665 qualified sentinels to make a new training. 21 is significant here for us, and the Unknown Soldier is the way we can honor the Unknown Soldier as the best way that we can. It also comes from the 21 gun scene as well. So, facing the 21 seconds, facing the 21 seconds down the map and making the 21 steps across the map is our way of honoring those Unknown Soldiers in every way that we can. As sentinels, remember, stand down from this post because those Unknown Soldiers are out there. They deserve that. They deserve our absolute best and everything that we can get from them. The sacrifice that they made is just a small comparison of what we have to go through out there for 30 minutes or an hour. So no matter how high it is, how over it is, the implement weather, we're always going out there for what they did for this country. It's us who owe those Unknown Soldiers our absolute best and everything.
