The Army has destroyed the last TMU-28B spray tank in its chemical weapons stockpile, filled with extremely toxic VX nerve agent. The Umatilla Chemical Depot had held 156 of the tanks and began the destruction campaign on November 23, 2007. Deseret Chemical Depot in Utah had held 862 of the Cold War-era dispersal devices, which were destroyed in 2004-2005. None of the other six chemical stockpile sites had held the spray tanks.
This milestone event received very little media attention. Alocal news organization noted the eventafter the Army sent out the press releases. The TMU-28B spray tank is perhaps more well-known because of the 1968 Dugway Proving Ground sheep incident, in which the Army was accused of sickening thousands of sheep due to an accidental drifting of VX aerosol 30 miles into a nearby valley.
