Is that a nuclear warhead in your backpack?

The Special Atomic Demolition Munition (SADM) was a family of man portable nuclear weapons fielded by the US military in the 1960s, but was never used in actual combat. The US Army planned to use the weapons in Europe in case of a Soviet Invasion. US Army Engineers would use the weapon to irradiate, destroy, and deny key routes of communication through limited terrain such as the Fulda Gap. US Army Special Forces were trained to jump the SADM into Soviet overrun/occupied western Europe and destroy power plants, bridges, and dams. In the 1960s, SADMs were deployed to Europe for use in the event of a Soviet Invasion.
