This was at our 50th 508th  Engineer Battalion OCS reunion in Washington DC 2018.  We were honored by the United States Army Old Guard Fife and Drum Corps.  It is one of four premier musical organizations of the United States Army. Members perform using musical instruments and wearing uniforms similar to those used by military musicians of the Continental Army during the American Revolution.
It is the only unit of its kind in the United States' armed forces, and is part of the 3rd U.S. Infantry ("The Old Guard"). The Fife and Drum Corps has been stationed at Fort Myer, Virginia, since its founding on February 23, 1960.

We get together every two years and now once a year.  Great Memories. I just posted a you tube video of them playing.  Like I said we were very honored to have them at our reunion.
