The GM (Gundam Mass Production), also referred simply as the Jim, is an Earth Federation mass production all-environment, generic, multi-role combat mobile suit based off the design and data obtained from the learning computer of the RX-78-2 Gundam more advanced prototype.
It is far less powerful and durable than the original Gundam due to heavily simplified and low-grade parts, but much cheaper to mass produce and easier to maintain, modify and repair. Due to its generally poor performance (being often depicted as a "cannon fodder" of some sort within the series), it spawned several variants, each with an attempt to make the mobile suit on-par with the more modern Gundams and whatever they were pitted against.
