In 1967 I, as a member of A Bty, was in Hohne in late Spring. This, by chance, coincided with the 50th anniversary of the Royal Tank Regiment. We subbies managed to lure some troopers who were parading themselves around Hohne playing "My Boy Willie" on various musical instruments into the officers' mess. This establishment had a reputation for snootiness, which was severely damaged by the event. Some cavalry officers objected, until we suggested the occasion called for special dispensation, and if they disagreed, we could discuss it in the parking lot.
And I was the FOO hanging on for dear life on the back of Recce Guy's steel chariot.
