COSTELLO: Of course today is Memorial Day. A time when the nation pauses to remember those who died while serving our country. At 11:00 Eastern, President Obama will lay a wreath at the Tomb of the Unknowns. Also on hand, one of the most elite groups of the U.S. army, the handpicked soldiers who stand sentry over the tomb and all that it symbolizes.</s>SPEC. NATE CHARTER, TOMB SENTINEL: It's an honor being able to work in Arlington Cemetery. There are some days where you just down like, like, hair raising on the back of your neck feeling that it's just right, that it is just perfect, you wouldn't want to work anywhere else for the rest of your life. Everyone worked on each other's uniforms even. To have somebody else around you taping you off, making sure there's no lint, debris or anything in there. May not look as good or may not look uniform to the other soldiers on the plaza. The reason why some of us may have certain things going out the door is because it's just worth for us during training to kind of calm us town before we go out the door. One of those things just give you motivation. It'd be like hey, I want to crush this guard thing. He's guard thing is going to be amazing. Yes. They started to heat in the place and then with the beam so bright it bounced off and hit you back. It just feels like the temperatures even warming than it is. If you're in your regular clothes. I do not think it was every going to be, guarding the Tomb of the Unknown Soldiers: We realize that that freedom isn't free. It really is and you have thousands of soldiers that die for our country. I don't look at it as just three unknown soldiers that I'm guarding. I'm guarding the 300,000 plus soldiers that have their life for this country.
