Technical and Historical Notes

In the last weeks of the One Year War, the Earth Federation Forces developed a much-needed medium-range fire support variant of its standard RGM-79 GM mobile suit. The result was the RGC-80 GM Cannon, but its late introduction into the war resulted in a rather limited production run. Following the war's end, the Earth Federation Forces began a massive reconstruction of its military, and one of their latest GM models, the RGM-79N GM Custom, served as the basis for the new RGC-83 GM Cannon II. The GM Cannon II, with its pair of shoulder-mounted beam cannons, more closely resembled the RX-77-2 Guncannon prototype from the war than it did the original RGC-80 GM Cannon. It carried the same standard GM rifle and shield as the GM Custom, and incorporated a more powerful generator to charge its beam cannons. The GM Cannon II was also armored with a thick layer of chobham armor, the same experimental armor tested on the RX-78NT-1 Gundam "Alex" near the end of the One Year War. However, this massive armor application greatly reduced the GM Cannon II's speed and mobility. The GM Cannon II did see limited production and deployment in UC 0083, with two units stationed aboard the assault carrier Albion during the Delaz Fleet's "Operation Stardust."
