In an alternate timeline where Vulcans had remained a violent and emotional species, the Interstellar Guard was the military space force of the Interstellar Union. The Guard evolved from the original Andorian Imperial Guard; when Andor, Earth, Tellar and Coridan joined to form the Union, the Guard became the military for that entire organization, and opened its ranks to admit anyone from a Union-member species.

In 2292, the Guard's flagship was the IUES Kumari II, under the command of Commander Hikaru Sulu, and its Field Marshal (Starfleet equivalent: Commander-in-Chief of the Federation Starfleet) was Thelianaresth th'Vorothishria. (ST - Myriad Universes novel: The Tears of Eridanus)
