The Enact from Gundam 00.


The Enact's production was launched in the year AD 2307 and the model was first introduced on the day of the Human Reform League's ten year celebration for the completion of its Orbital Elevator. The Advanced European Union,
whose Orbital Elevator was still in an incomplete state, had staked its
organization's prestige on the development of this new solar
energy-adapted mobile suit. The demonstration unit was operated by AEU
ace pilot Patrick Colasour, who had won over 2,000 mock battles, only to be heavily damaged by the GN-001 Gundam Exia during its demonstration.



Although its abilities were virtually identical to the Union's SVMS-01 Union Flag,
the Enact's design incorporated the latest in mobile suit technology
making it one of the most advanced mobile suits to date in AD 2307.
However its capabilities were quickly overshadowed by the Gundam Exia
which defeated an Enact piloted by one of the AEU's top aces with ease,
completely destroying the unit's head and arms without damaging the
cockpit. This humiliating defeat would delay the Enact's launch, but
that did not stop the PMC Trust
from making use of the mobile suit. Enacts operated by both AEU
military and PMC Trust would later take part in battles against
Celestial Being's armed intervention with little success.



Some months after the introduction of the Enact the Union, AEU,
and HRL would unite together and create the United Nations Forces that
would use the GNX-603T GN-X. This was the precursor to the establishment of the Earth Sphere Federation
which would mass-produce the GN Drive Tau technology and production of
previous non-GN powered mobile suit models such as the Enact would cease
in favor for the more advanced mobile suits of the GN-X series.



By the year AD 2312 a significant number of Enacts were still in service for the Earth Sphere Federation Army despite being outmatched by the GN-X series of mobile suits. Much like some of the older and outdated units, such as the SVMS-01 Union Flag and MSJ-06II-C/B Tieren High Mobility Type B,
the Enact was used as a stopgap method of supplying the Earth Sphere
Federation Army with machines because of how GN-X series has limited
operation time and requires specific facilities for recharging.^[7]
The Enact and its variants were also acquired and used by various
independent factions and anti-federation organizations such as the Kingdom of Suille and Katharon.
