The Cold War Chemical Weapons Depot Today

AO5Y8539Out in the Eastern Oregon desert, the U.S. Army built a massive facility in 1941 as part of its pre-war expansion program. Called the Umatilla Army Depot, this bleak spot in the middle of the desert, not far from the Columbia River served as a storage facility for ammunition and basic supplies for units in the Pacific.  During the war, Umatilla housed a 30 days supply of ammunition for all the U.S. Army divisions deployed against the Japanese.

To safely keep ordnance stored, the Army built hundreds of concrete igloos that still exist today. They’re like gigantic vaults with massive metal doors. Some are surrounded by berms or revetments for additional protection in case of an accidental explosion.

AO5Y8552During the Cold War, the Army chose Umatilla as a storage site for about twelve percent of the United States’ stockpile of chemical weapons. Everything from blister agents to VX gas was stored in L Block, which was sort of a base within the base complete with its own security fence and check points.  Those weapons were destroyed at a purpose-built incinerator built next to L Block in the 1990s. The work lasted for years, finally finishing up in 2011.

The base was subsequently handed over to the Oregon National Guard, which transformed it into the home of the Regional Training Institute. Today,  the ammunition igloos are used as high ground in field exericses by the RTI’s MOST classes and NCO courses. A rifle range has been added as well.  It is an amazing way to re-purpose a World War II era base, and ongoing work has upgraded the base’s new capabilities with such things as a small MOUT site.

My OPFOR group of volunteers, the 973rd Civilians on the Battlefield, provides training support to the RTI’s NCO classes. We’re their bad guys, defending the MOUT site, executing simulated ambushes, moving to contact, etc. Being out there among the many abandoned WWII-era buildings is one of the most unusual experiences we’ve had. We’ve supported the RTI since 2008 when the courses were conducted at Camp Rilea on the Oregon coast.

This last week, we were on the ground at Umatilla again, working with the awesome NCO’s and officers of the Regional Training Institute to help make the class experience in the field as realistic as possible. The photos here were taken during the final phases of an NCO training course. We’re looking forward to many more days with the RTI on the ground at Umatilla, rolling as their OPFOR! After ten years, the experiences on the range with these incredible and dedicated citizen-Soldiers remains among the most meaningful of my life.
