Pre-BATCO systems used a series of appointment titles to identify users and individuals, "Sunray", for instance, referring to the appropriate leader. Most appointment titles are no longer used by the British Army, but titles such as "Sunray" and "Sunray Minor" are still used; appointment titles also continue to be taught during Community Cadet Forces communications training. Several other Commonwealth militaries and cadet forces used or continue to use appointment titles, including those of Australia, Canada, New Zealand, Rhodesia (now Zimbabwe), and Sierra Leone, with some usage by the United States military and various NATO countries also occurring due to a list of appointment titles being included in ACP 125; Commonwealth and ACP 125 appointment titles have a high degree of commonality with those used in British service, though differences, additions, and subtractions can be found (the British themselves used an altered version of their appointment title list during Operation Banner where certain titles had different meanings than usual or were replaced by alternative titles). Where there is continued usage of appointment titles, they are usually regarded as only giving a low grade of security cover, with ACP 125 deeming them to be unclassified.
