TS-MB1B Euclid

The TS-MB1B Euclid is a mass-produced mobile armor of the Earth Alliance, designed using data from the YMAF-X6BD Zamza-Zah and YMAG-X7F Gells-Ghe prototypes. It is capable of both air and space combat, and is armed with two M464 "Detyarev" high-energy beam cannons and two M551 septuple Gatling guns. In addition, the Euclid incorparates a positron reflector shield, a SC1021 "Schneid Schutz" model, similar to its predecessors. However, the Euclid lacks limbs, making it more like the TS-MA2 Moebius in design.

The Euclid makes its combat debut in the Battle of Heaven's Base, when several dozen units are among the forces fielded to defend against ZAFT's attack on the base. Later, additional Euclids are fielded in space to defend the orbital relay points of the satellite reflector cannon "Requiem", as well as the "Requiem" cannon itself.
