The RGM-79 [M] GM Marine Type is a mass-production amphibious mobile suit that appears in the ONA adaptation of Mobile Suit Gundam Thunderbolt.

Technology & Combat Characteristics

The GM Marine Type is based on the RGM-79C[G] GM Ground Type-C and modified for use in marine environment.[1] It has hydrojets on its shoulders, knees and backpack to propel itself underwater.[1] To adapt to underwater combat, it carries a needle gun that fires solid projectiles.[1]


  • Needle Gun
A special rifle that uses compressed air to launch solid metal needles that can pierce most armor, including those of submarines and amphibious mobile suits.


In August UC 0080, multiple units were dispatched by the assault carrier Spartan for a patrol mission near Antarctica. They were then ambushed by several MSM-07 Z'Gok piloted by Zeon remnants and suffered heavy losses. Several were crushed by sinking icebergs. In the manga, the GM Marine Types were later used to stop traffic from leaving the Rig.
