This is the Engineer Regiment's Stained Glass Memorial dedicated years ago to recognize those engineers who served during the Cold War period.
It's located in the original portion of the Army Engineer School building opened in 1988, and which is now no longer used by engineer students there, who attend classes in a newer addition. Thus, I wonder if those students are aware of its existence. Perhaps they do find the beautiful and solemn memorial as they move about the large modern facility, but I still wonder whether this is so. My point is, we need to always remember those who have gone before...and one way to do that is to seek out memorials of this nature, and offer thanks in some way.
