RGM-79 GM

At the onset of the One Year War, the Earth Federation did not take the mobile suit threat seriously. This was until the Principality of Zeon's MS-06F Zaku II completely decimated the Earth Federal Spaces Forces in space and then invaded Earth. Thus the Federation developed several mobile suit prototypes, the most notable of that being the RX-78-2 Gundam. From the Gundam came the Earth Federation's first mass production mobile suit: the RGM-79 GM. The GM would serve as the Federation's primary mobile suit throughout the war. The GM would also serve as the baseline of the Earth Federation's mobile suits for over fifteen years.

The GM was armed rather simply, with most of its weapons basically scaled down verisons of that of the Gundam. The GM was generally sent into battle with a Beam Spray Gun, a single beam saber, and its pair of 60mm Vulcan guns mounted in the head.
