RGM-79 GM (Thunderbolt anime)

The Earth Federation Forces were caught flat-footed when the Principality of Zeon deployed mobile suits at the start of the One Year War in UC 0079, thus changing the face of warfare forever. The EFF scrambled to catch up its own lagging mobile suit development and initiated Operation V, which led to the creation of the RX-78-2 Gundam. Combat data from the Gundam’s learning computer, combined with the pre-production RGM-79(E) GM Early Type, contributed to the development of the mass production RGM-79 GM. While the standard production model GM removed the Core Block System, it was retained in units used by the Moore Brotherhood and deployed to Side 4’s Thunderbolt Sector, as well as some regular EFF units that participated in Operation Star One. These units featured a new space backpack that utilized a pair of sub-arms that could hold two shields. They also featured sealed joints to protect the suit from space debris. In addition to the shields, these GMs were armed with a twin beam rifle and beam spray gun.
