XRS Callsigns

XRS Callsigns are special callsigns XQ uses for their agents when on official military-type endeavors. Like most types of group-related callsigns, XRS Callsigns have multiple numbers for each name. Unlike most of them, however, XRS Callsigns usually include a trait linked to the agent using that callsign (such as elemental abilities, as seen with Taylor Johnson and Rochelle, or other squads an agent is linked to, as seen with XQ's Angel Squadron).

History
It is believed XQ came up with the XRS Callsigns at about the same time XRS Command was created as a military communication hub. Using a unique naming and numbering scheme based on the agent using a specific callsign, anyone knowing of XQ's roster can immediately identify the true identity of an agent based on their XRS callsign. Some agents even have multiple XRS Callsigns to potentially confuse enemies.

The XRS Callsigns were first used during 'Psi Mu Omega' by Anise in communication with XRS Command, and such callsigns were then used on other agents assisting Anise in subsequent military operations. XRS Callsigns even appear on XQ-linked people who aren't official XQ agents, as seen with JB93 native Madison when she provided assistance in the fifth and seventh operations in 'Psi Mu Omega'.
