RGM-79SC GM Sniper Custom/Origin

The RGM-79SC GM Sniper Custom is a mobile suit from Mobile Suit Discovery.

Design & Development
The Earth Federation Forces was lagging behind the Zeon army in the number of mobile suit deployments. It adopted the RGM-79 GM, which was a greatly simplified RX-78 type machine to catch up. It succeeded in mass production and deployment in a short period of time. However, the combat capabilities of a single unit was inferior to Zeon's mobile suits. A request for improvements was made by skilled pilots.

The RGM-79SC is a comprehensive performance enhancement type of the GM, with specifications comparable to that of RX-78 type machines. The backpack was equipped with large thrusters and mobility was enhanced with leg sub-thrusters. It was called "Sniper Custom" because it was equipped with a long-ranged beam rifle.
