A modified version of the Gelgoog for local warfare. It was designed for operation in the desert, with dustproofing measures applied to various parts, and to deal with heat problems, the cooling system was strengthened, and the built-in power pipes were exposed to the outside, to thoroughly dissipate heat and cool the machine, making it possible to withstand long hours of operation in the desert.
To ensure mobility under gravity, thrusters were added to the legs and a backpack was also installed. The arm-mounted jet propulsion systems, which are redundant for sub-gravity combat, have been removed, and the left forearm is equipped with the distinctive Armed Buster, a collapsible projectile weapon. Additionally, the backpack is equipped with a scope for observing the surroundings from within the trenches or in the sand, making it an machine that excels in guerrilla warfare and covert operations.
During the One Year War, a very small number of Desert Gelgoogs were used on the African front. In U.C. 0096, a Desert Gelgoog was deployed by Zeon Remnants for the assault on the Federation's Torrington Base and was destroyed by the RX-160S Byarlant Custom.
