GNMA-00GR GAMMA

The GNMA-00GR GAMMA is a prototype support mobile armor. Even though it is often called an MA, it was developed and deployed as more of a Mobile Fortress. The unit is controlled by CHEL.

Technology & Combat Characteristics
During the battle of Eden, KME fielded the GNMA-00GR GAMMA ("GR" stands for "General Resupply"), a massive mobile armor designated as "Mobile Frontline Bridgehead" created by combining a modified Regnant with "the fuselage of a cruiser". The class of the ship used is unknown. The MA's fuselage seems to share no exterior or hull features with any known ship; thus, it may be possible that the "fuselage" referred to may simply be large components from another ship - recovery systems, the reactor, etc. The Big Rang's powerful reactor supposedly allowed it to quickly replenish its energy supply (although CHEL, the unit's AI), was dissatisfied with the recharge rate of the main beam cannon aboard, and was reduced to firing short low-power bursts soon after entering combat). The most important feature of the MA, however, was a modified catapult/hangar within the lower body, which allowed Mobile Suits to dock, repair, resupply, and continue fighting; in essence, it vastly extended the combat period for both the original Regnant and ally MS. However, despite it's enormous size, it was capable of moving of moderate speeds and sometimes high velocity in short bursts.

Armaments

 * GN Claw Arms
 * For GAMMA, its main form of close combat armament are a pair of large, GN claws mounted on unit's long arms. The claw arms were modified version of Regnant's original with enhanced claw joints and forearm coolant tanks. They are normally used for grabbing at enemies and causing massive damage with a combination of the claw's strength and the momentum built up by the mobile armor. They can also be used as wire-guided bits.


 * Mega Particle Cannon
 * Mounted in the front of MA's control unit is a powerful mega particle cannon. This weapon has been shown to have enough power to destroy several Baikal-class cruisers with a single shot. The mega particle cannon is powered by GAMMA's powerful reactor which is supposedly to quickly replenish its energy supply. Actual combat had shown its power supply is unstable to render Big Rang to fire short bursts of low-power mega particle shots thereafter, but they are just as deadly against Old Human Faction's warships.


 * 4-tube Missile Launcher
 * Located just behind the control unit's mega particle cannon are a pair of 4-tube missile launchers which serve as secondary weapons in situations when the cannon is in the process of charging or is ineffective against an opponent.


 * Gatling Cannon
 * Located on the left side of the control unit is large-caliber multi-tube Gatling cannon which serves as the Big Rang's secondary weapon in situations when the mega particle cannon is ineffective or inappropriate against small, fast-moving opponents such as mobile suits or mobile armors. The Gatling Cannon has a high-rate of fire and it is able to damage the armor of mass-produced mobile weapons.


 * 30-tube Counterbeam Chaff Launcher
 * The GAMMA is equipped with a total of 4 rectangular Counterbeam Chaff Launchers (30 tubes in a 6 x 5 array), with 2 on each front side of MA's GR unit. Once launched, each counterbeam chaff forms a temporary anti-GN beam coating surrounding GAMMA's immediate cavity, which is able to withstand the beam shots from ESF's Baikal-class' main guns for a very limited time.


 * 3-tube Large Anti-Ship Missiles
 * The GAMMA is equipped with 2 sets of 3-tube large anti-ship missiles, with each set being located at the rear of MA's GR unit. A single missile is powerful enough to destroy a ESF's Baikal-class cruiser.
