“As part of a agreement with joining the United Nations and Russian Federation, NATO has come to assist Equestria with improving security across the nation and neighboring lands. After what happened during the Canterlot Wedding, Generals Lance and Viktor have approved the formation of a special forces unit within the royal guards. They would be known as the Canterlot Rangers.”

Part of the contract that allowed Equestia to join the U.N., the Canterlot Rangers is a special forces unit mainly under the command of the princesses. Tasked with maintaining order and going on classified operations. Many of these operations only allow a few or one operative to be in as to not allow unwanted attention from the villains of the world. In some cases they can be secretly protecting the elements of harmony to ensure no one tries to influence them.

Justin was recruited into their ranks as his skills in close combat and marksman's skills. He was chosen as Celestia’s personal ranger as he only takes orders from her. Even though he’s young, the title allows him the rank of a captain, but being still young and in training he is yet to fully earn the rank. However, Princess Celestia has high hopes for the gryphon and sees that he is special even with his condition that turned him into a gryphon. She believes he will show what it truly means to become a Canterlot Ranger.
