Masters-at-Arms and other kinds of security officers utilise a radio code system in order to prevent intelligence leaks during emergencies or during patrols. On mainline military vessels, radio codes are typically not employed unless the ship is in currently in Condition Amber, Blue or Red to prevent intelligence leaks, but radio codes are frequently used on vessels with civilian contractors for the same reason police officers utilise radio codes. Security Radio Codes used by the Sol Defence Corps also employ suffixes.
It is HEAVILY recommended to use these radio codes cosmetically. Many roleplayers may not know about this article and will be effectively shut out of the roleplay. For example, frame your actions like this:
"10-43, please inform medical of an injury in the shuttle bay."
"10-41, (fight in progress) Deck 02 hallway."
