Thanks much for your curiosity about The Old Guard of the Army, the 3rd Infantry Regiment that is the oldest active infantry unit of the Army, since 1784, posted to Ft. Myer Va., next to Arlington National Cemetery and the Pentagon since 1948 as "The Official Escort To The President" unit of the armed forces.
The principal mission of the ceremonial unit of each armed service in Washington DC is to conduct military funerals in ANC. Each service member selected for this mission is awarded the high honor and privilege to perform these solemn and sacred duties. I did this myself in TOG from 1966-70, during which time I participated in more than a thousand Army honors funerals or full honors funerals to include some Joint Force funerals and state funerals.
The overriding mission of these Washington DC units of the Army, Marines, Navy, Air Force, Coast Guard is the defense of the nation's capital and area under the Joint Force Headquarters - National Capital Region that is in the Washington background of the video, at Ft. Leslie J. McNair. In the upper right of the video frame, on this side of the Potomac, we can see (and hear) some of Reagan National Airport that uses the Potomac as the landing approach path.
JFH-NCR is a part of Northern Command at Peterson AFB, Colorado that consists of the 5th Army and the 1st Air Force with some units of Marines and Navy to include CG. 3 IR TOG is a part of the 5th Army and continually rotates one company deployed abroad in a combatant command. Sen. Tom Cotton was in TOG too although I don't say that too loudly ha.
All the same it's good to lighten up somewhat as we sort of do in this video that I wanted to post in reply to your excellent post. The video records four 5th graders from the Betsy Ross Elementary School in Washington DC placing a wreath at the Tomb of the Unknowns. The video opens with TOG commander of the relief instructing them in the procedure. I challenge anyone here ha to follow these instructions issued by the TOG Sergeant E-5 commander of the relief that these four children did precisely. Everyone agrees these boys and girls are amazing.
So I see I'm still not smarter than a 5th grader. Certainly not these 5th graders at the Ross Elementary in upper Northwest Washington DC that includes Georgetown, National Cathedral, The American University, St. Albans School for Boys and so on. The neighborhood of this public school includes "Embassy Row" on Massachusetts Avenue. The non-profit GreatSchools says, "Most students at this school are performing at or above grade level."
Ross Elementary consists of learners who are 49% white, 19% Hispanic, 16% black, 9% Asian, 7% of two or more races. Being a boy at this school has its advantages too btw as 60% of the learners are girls.
And check out the four kids at the end after they're released by the Sergeant ha. You'll wanna pinch each cheek hah.
