Having witnessed the all-range attack of Principality of Zeon's Newtype-use mobile armors, the Earth Federation Forces began their own development of weapons with said capabilities. Since the Earth Federation was far behind in Newtype research and had little understanding of Psycommu technology, they had to figure out how the system worked. The GM Juggler represents the Earth Federation Forces' early attempt to imitate guided remote attacks using existing machines. The RB-79 Ball was remodeled into an attack pod, and two such pods were mounted on the back of a RGM-79 GM, and the mobile suit's cockpit was diverted from the TGM-79 GM Trainer to make it a two-seater, enabling a gunner to manually control the attack units. In addition, the RX-78NT-1 Gundam NT-1's Chobam Armor, which was being developed at the time, was used to improve defenses to deal with the gaps during manual control.

Unfortunately, the manually-controlled all-range attack never performed satisfactorily, and the added bulk of the remote attack units contributed to excessive topweight and consequently poor balance of the GM Juggler. Repeated improvements were made to overcome these flaws, and this continued until the end of the One Year War without producing a viable result. With the latest Psycommu technology falling into Federation hands by the end of the war, the GM Juggler was no longer needed, leading to an end of its development.
