A friend of mine at the USAARENBD had been a Combat Engineer officer at Vicenza, Italy during a previous assignment.
One day, he and an NCO were driving to a deployment site and got lost.
They somehow ended up driving along a long causeway. As they continued on, they started seeing red flags along the sides of the causeway. Soon they saw that they were approaching one of those stereotypical European "seesaw" style frontier gates. Reorienting their map, they realized that they were about to drive into Yugoslavia.
Very quickly, they threw the 5 ton into reverse, taking them... and their Atomic Demolition Munition (ADM) swiftly away from Tito's "worker's paradise".
