RMS-179 GM II The GM II was formed the backbone of the AEUG mobile forces. The AEUG developed the MSA-003 Nemo as a replacement for the GM II but production was slow and many Nemo units were destroyed in the Gryps Conflict. Thus, the many GM II units were fielded once more to cope with the shortages.
