Sudbury Training Annex

The Fort Devens Sudbury Training Annex, or "Ammunition Dump" as the Annex is locally known, is an inactive 2,450 acre site. The Annex was most recently used by Army reservists for troop field training during Desert Storm.

Established in the early 1940s as the Maynard Ammunition Depot, the installation became known as the Maynard Ordnance Test Station after World War II. In the mid-1950s, the facility became known as the U.S. Army Natick Research and Development Command and was used for troop training and disposal of certain wastes from Natick Laboratory.
