RN SHIPS DIVERS: Officers and Ratings from all branches could apply. Members of the RN who volunteered as Ship's Divers underwent a one-day aptitude test, concentrating on swimming ability and suitability for diving.
Those selected went on a four-week course, which consisted of basic compressed air (open-circuit) diving. There was also extensive instruction (and practice) on searching ships bottoms for explosives, as well as instruction in working on ship's hulls, decompression chambers and maintenance of diving equipment.
On completion, the diver returned to his ship or shore establishment and to maintain their qualification (and get their diving pay) were required to dive for at least 120 minutes during each four-month period.
CHALLENGE COIN: is a small coin or medallion, bearing an organisation's insignia or emblem and carried by the organisation's members. Traditionally, they might be given to prove membership when challenged and to enhance morale. They are also collected by military & service members and law enforcement personnel.
Modern challenge coins are made in a variety of sizes and are often made using popular culture references. Historically, challenge coins were presented by unit commanders in recognition of special achievement by a member of the unit. They are also exchanged in recognition of visits to an organisation.
