The RGM-79[G] GM Ground Type is a ground based predecessor to the RGM-79 GM. It first appeared in Mobile Suit Gundam: The 08th MS Team.

An early prototype of the Earth Federation Forces' mobile suit mass production project, the GM Ground Type was developed before the RX-78-2 Gundam's operational data was recovered. Even though it was only able to operate on Earth, its internal parts were all tuned for ground combat, and it was equipped with Luna Titanium armor, causing its mobility, maneuverability, and general performance to surpass the later RGM-79 GM.It is said that its performance under gravity even rivals that of the RX-78.The GM Ground Type was a simplified version of the RX-79[G] Gundam Ground Type, and produced using the same production line.Compared to the Gundam Ground Type, the GM Ground Type omitted the chest-mounted Vulcan gun and multi-launcher, the weapon container mount on the backpack, and was equipped with a less powerful generator.It also did not incorporate parts from the RX-78 series, though its head unit was similar in specs to that of the RX-78's.Since it was produced after the production format was established, its ease of production, ease of maintenance and availability of parts were all greater than its predecessor.Due to its use of Luna Titanium alloy, it was unsuited for mass production and produced in limited numbers. However, the GM Ground Type was important in establishing the EFF's mobile suit production framework. The operational data it collected contributed to the development of later mobile suits.Finally, the basic structure of its head was later inherited by the RGM-79 GM, becoming the iconic face of Federation mass production mobile suits.
