The RGM-79D GM Cold Climate Type is an Earth Federation Forces mobile suit from the Universal Century.

Technology & Combat Characteristics

While the RGM-79 GM proved itself to be a highly capable MS, the introduction of Zeon's well armed and agile MS-09B Dom on Earth saw the need for a more maneuverable and better-performing mobile suit. A variant of the GM, the RGM-79D GM Cold Climate Type had increased thruster power and maneuverability, and some were modified for harsh climate conditions, most notably cold weather combat. The RGM-79D could be equipped with a variety of weaponry, including two types of 90mm machine guns (one of which is fitted with an underslung grenade launcher), head-mounted vulcan guns, and a beam saber.


  • 60mm Vulcan Gun
The GM Cold Climate Type is equipped with a pair of head mounted 60mm vulcan guns. These shell firing weapons have a high-rate of fire but have little power, however, they are effective at close range and is commonly employed as a deterrence tactic to keep an enemy mobile suit from getting too close. The weapons are ideal for shooting down small, fast moving, lightly armored targets such as missiles, small land vehicles, and attack helicopters.
  • Beam Saber
The beam saber is a small cylindrical device held in the mobile suit's hands when operated and is powered by an energy capacitor that is recharged from special racks. The beam saber emits a blade of plasma contained by an I-field and is capable of cutting through any metal alloy. The only way to block a beam saber is to counter with another beam saber or to use armor that has been treated with an anti-beam coating. The GM Cold Climate Type carries one beam saber, that when not in use is stored on the backpack.
  • HWF GMG·MG79-90mm Bullpup Machine Gun
The bullpup machine gun is an open-bolt, gas-operated, magazine-fed, mobile suit handheld sub-machine gun. It does not require energy to be used, however it is ineffective against heavy armor. When the magazine is empty, it can be discarded and replaced with a new one.
  • NFHI GMG-TYPE2 90mm Bullpup Machine Gun
Beside the HWF GMG·MG79 Bullpup Machine Gun, the GM Cold Climate type also fields the newer NFHI GMG-TYPE2 model. It's unknown whether there is any noticeable increase in performance. However, it's integrated with a Grenade Launcher under its barrel for more firepower.
  • Grenade Launcher
The NFHI GMG-TYPE2 90mm Bullpup Machine Gun is fitted with an underslung grenade launcher, which can fire a variety of grenades. These grenades are not very effective against large ships, but are ideal mid-range anti-mobile suit weapons.
  • Shield
The shield is a thick sheet of armor designed to take severe punishment that would normally destroy a mobile suit. Since the introduction of beam weaponry, shields have been treated with an anti-beam coating allowing it to withstand several beam shots before the coating wears off. Typically physical shields can only take so much damage before they succumb to the pressure and break.


The RGM-79D was introduced late in the war, with at least three units assigned to Lieutenant Yuu Kajima's MS combat testing squad. Yuu Kajima's unit quickly proved the value of the new model GM in combat, destroying several Zeon mobile suits in defense of a Federation Forces base, including several units of MSM-03C Hygogg and three Doms. Other units were deployed to guard important Federation Forces bases, such as the Arctic base where research and development of the RX-78NT-1 Gundam "Alex" was carried out.
