DoE OST Western Command -Department of Energy

The Office of Secure Transportation (OST) is responsible for the safe and secure transport of government-owned special nuclear materials in the contiguous United States. These classified shipments can contain nuclear weapons or components, enriched uranium, or plutonium. Cargo is transported in highly modified secure tractor-trailers and escorted by armed Federal agents in other vehicles who provide security and national incident command system response in the event of emergencies. This dual-sided challenge coin features a nuclear radiation symbol with crossed swords and a skull on the obverse representing OST Western Command, and the official Department of Energy Federal Agency badge on the reverse dated 1975.
