The Earth Federation Forces were caught flat-footed when the Principality of Zeon deployed mobile suits at the start of the One Year War in UC 0079, thus changing the face of warfare forever. The EFF scrambled to catch up its own lagging mobile suit development and initiated Operation V, which led to the creation of the RX-78-2 Gundam. Combat data from the Gundam’s learning computer, combined with the pre-production RGM-79[E] GM Early Type, contributed to the development of the mass production RGM-79 GM. To mass produce the Gundam, several compromises were made, such as removing the Core Block System, removing a beam saber and replacing the powerful beam rifle with a simpler beam spray gun or machine gun. As the EFF ramped up its production lines, the standard GM made its wide scale debut following the Battle of Odessa in November. Multiple variants of the GM were deployed as the EFF pushed the Zeon off Earth. In space, GMs were used in large numbers during Operation Cembalo and Operation Star One. After the war, the EFF continued to produce GM variants and upgrades, and its successors in the RGM series saw wide use as late as UC 0223.
