Technology & Combat Characteristics
A variation of the MS-14 Gelgoog, the MS-14F Gelgoog Marine was developed from the MS-14B Gelgoog High Mobility Type. Being designed for the Zeon Marine Corps, its power-to-weight ratio, mobility, and maneuverability were all greatly improved, rivalling the later MS-14JG Gelgoog Jäger. Though the Gelgoog Jäger's performance was still superior, the Gelgoog Marine's production cost was lower, and was thus produced in greater number. it was equipped with a pair of 110mm machine cannons. Its other weapons include a pair of beam sabers and a spike shield that doubles as a melee weapon.
History
The development of the Gelgoog Marine began just as the development of the MS-14A concluded. Astoundingly, the change in design took only half a month, a fact that was lauded by the military PR department as "Zeonic Magic". However, the development lead of the project died from overwork as a result.
Prior to the implementation of the United Maintenance Plan, the Gelgoog Marine had a short production run at the A Baoa Qu factory. Due to its late production period and deployment, it is believed that only a small number of units participated in the One Year War. Around 30 units were assigned to Cima Garahau's Cima Fleet at some point during the war, with 6 units assigned to the flagship Lili Marlene and the rest spread across seven Musai-class Late Production Type. It is said that Cima used her personal connections to get these mobile suits assigned to her fleet, though this is unconfirmed.
On October 31, U.C. 0083, the Cima Fleet, which had aligned itself with the Delaz Fleet, attacked the Albion while it was searching the shoal zone. Five Gelgoog Marines participated in the battle, later joined by Cima herself in her Gelgoog Marine Commander Type. The attack ultimately failed, and Cima was forced to retreat after losing two Gelgoog Marine. On November 8, while attempting to trade the plans for Operation Stardust to the Federation, the Cima Fleet engaged the Albion once more, with South Burning shooting down two Gelgoog Marine in his RGM-79N GM Custom. On November 10, the Cima Fleet hijacked two colonies that were being transported as part of the Colony Reconstruction Plan. Gelgoog Marines were used to plant explosives on the colony mirrors, causing them to collide with one another.
During the final phase of Operation Stardust, however, the Cima Fleet betrayed the Delaz Fleet and joined the Federation in stopping the colony drop. Following the conclusion of Operation Stardust, one captured Gelgoog Marine was seen being used as a training unit at Earth Federation's Oakley Base.
