Gelgoog integrated development plan during late OYW was unable to be carried out full scale. Therefore these Gelgoog variants also appeared to fill specific mission roles, and one variant was the MS-14F Gelgoog Marine. Built exclusively for Zeon's marine troops, the Gelgoog Marine featured improved thrusters, speed and maneuverability, as well as external propellant tanks to increase its range while offsetting the extra fuel used by its more powerful thrusters. For a start, they are deployed for special mission, recognized for their thick armor. Their verniers and radiation tank are large in size which account for the outlook.
Just like the Zaku, the leader type will have antenna on the forehead. The marine model was later diverse or improved to Jaeger as time established. Head design of most Gelgoog are almost identical. There is heat dissipating fin that goes right to the back of the head. Gelgoog Marine, larger seen in year UC 0083 within Delaz Fleet, participated in the deployment of Solomon Nightmare to rally the Principality of Zeon. They are a serious threat to Albion Corps as these former principality army, remains as one of the best high-performance machine grunt units. Gelgoog Marine's standard equipment is a machine gun (80-90mm machine gun principality military equipment capable of late-type firearms grenade launcher for the general MS) instead of a beam rifle, unless pilot fall under the Ace category.
This MS is specialized for substantially space combat, since the operating time and cruising distance extension, it will be equipped with a propeller plant tank large. Instead of spike shield mount on shoulder like Zaku, Gelgoog effective latched it to forearm shield, an obvious equipment of offense and defense together that was so even used in the equipment to defense also attacked the spike. The twin beam sword of the original Gelgoog was replaced with two standard beam sabers, and a 110mm machine cannon was mounted on each forearm.
