The OZ-00MS2B Tallgeese III

Tallgeese III is a variant of Treize Khushrenada's OZ-00MS2 Tallgeese II and started development around the same time as the building of that unit; however, it wasn't finished in time for Treize to take it with him to space. After the Eve Wars' conclusion, the Tallgeese III was confiscated by the Earth Sphere United Nation's Preventer taskforce and kept in storage.

In AC 196, when the Mariemaia Army declared war on the Earth Sphere Unified Nation, former OZ ace pilot Zechs Merquise returned from hiding to work for the Preventers. Zechs was assigned the code name Wind and given Tallgeese III to fight against Mariemaia's Army. He first attacked them in space while they launched from their base MO-III. Using the suit's beam saber, Zechs cut down several ships but had to stop when Dekim Barton threatened to throw a colony at Earth. When Dekim fled, Zechs used the suit's mega cannon to destroy the asteroid base. Later, Zechs used the Tallgeese III to pacify Mariemaia's army of MMS-01 Serpents in Brussels without killing any of the pilots.
