During the Cold War, Camp Rapid continued to host and support National Guard activities, including a series of annual exercises involving National Guard troops from many states conducting operations in the Black Hills. In the early 1990s, a new series of building projects replaced tent pads and brick and metal tents with permanent structures for use as armories, barracks, and support facilities. Security of the Camp was upgraded significantly in the early 2000s as part of nationwide security improvements. While small, the camp is a showcase for the National Guard and one of three active, manned military installations remaining in the Black Hills, and one of four in South Dakota.
