The RGM-79SR GM Sniper III Medium Range Support Type (also known as the RGM-79SR GM Sniper III Cannon Pack Test Type) is a mobile suit that appears in the photonovel Advance of Zeta: The Flag of Titans.
Technology & Combat Characteristics
The RGM-79SR GM Sniper III Cannon Pack Test type is a version of the long-range support mobile suit GM Sniper III which is equipped with a medium-range support unit, or "cannon pack," for increased firepower. The addition of this cannon pack disrupts the GM Sniper III's mass balance and reduces its originally high maneuverability, but dramatically increases its firepower. Although beam weapons are the standard armament at this point, because the GM Sniper III carries a high-output long-range beam rifle, the cannon pack uses a projectile cannon to reduce the load on its generator. It also carries a RMS-117 Galbaldy β extendable shield. Since the beam rifle's high output causes severe superheating in its barrel, two replacement barrels are attached to the shield.
Medium-Range Support Unit: This so-called "cannon pack" allows normal mobile suits to reproduce the functions of medium-range support machines like the RGC-80 GM Cannon through a simple backpack replacement. The old Principality of Zeon previously apply the same concept to create the MS-14C Gelgoog Cannon.
