A heavily armored and highly maneuverable Gundam-type mobile suit deployed by the Moore Brotherhood. There was another type of Full Armor Gundam with similar model number, the FA-78-1, but it had different details and equipment. Both mobile suits were developed under the ‘Full Armor Operation’, and their differences were a result of experimenting with various systems and equipment.
The Full Armor Gundam was fitted with numerous pieces of body armor, a large backpack and had much more weaponry than other mobile suits of its time. Like other mobile suits of the Moore Brotherhood, the Full Armor Gundam had special seals on its joints and large backpack to protect them from the debris drifting in the Thunderbolt Sector. Besides the standard beam sabers, it was also armed with a twin beam rifle, five rocket launchers, a large beam cannon, a 6-tube missile pod and numerous missiles stored in various body armor.
