The GM II is a minor revision of the mass-produced
mobile suit
used by the
Earth Federation Forces
during the
One Year War.
While it's undergone modest improvements to its armor materials and
sensor systems,
and been fitted with the standard
linear floating seat
and
panoramic screen,
the GM II is no match for modern mobile suits. In the early stages of the
Gryps Conflict,
this obsolete machine is used by both the
AEUG
and the Earth Federation Forces, but it's soon retired in favor of newer models.
