Concrete placements are underway for a container storage shed located on the northeastern side of a $115 million, 2-story project by the U.S. Army Corps of Engineers – Far East District at Camp Humphreys, South Korea, Dec. 23, 2025. A feature of work underway is installation of metal structures called revetment walls or “cells” to protect military personnel testing and/or conducting maintenance on aircraft. They will eventually be filled with sand, which is more cost effective and alleviate the impacts of high-speed flying objects.
