Technology & Combat Characteristics
The RF Zaku is the product of combining Principality of Zeon Mobile Suit (MS) designs with the designs of AMS-119 Geara Doga by Oldsmobile Army engineers. Although its outward appearance was virtually identical to the original MS-06 Zaku II, it was considered as "replica" unit constructed from modern materials making it much lighter. Even though it had external power pipes. they served no purpose other than to further replicate the older Zaku II's aesthetic. Because of that its exterior can be swapped other configurations such as FZ Type , F2 Type, Marine Type, RF Gouf Type, and High Mobility Type, although its standard configuration was Zaku II Type.
Despite being built with universal standard, the RF Zaku Early Type had overall lower performance than Earth Federation Forces' RGM-89J Jegan Normal Type. The cause of its lower performance was by its design philosophy to combat older mobile suit design such as Jegan Normal type and RGM-87C2 BR-GM C2, rather than state of the art mobile suits like RGM-109 Heavygun or the F71 G Cannon. Despite its inferior performance, it fulfilled its intended role as guerilla unit against lightly defended Earth Federation facilities, while also capable to perform on equal or slighly superior performance than Federation's Jegan Type thanks to its smaller size and higher turning rate. Due to its usage of modern components the RF Zaku Early Type capable using weaponries used by Geara Doga and Geara Zulu if such weaponries available, but its usually equipped with conventional weaponries due to practical and logistical reason. Due to its relatively successful performance, the Oldsmobile Army would overhaul its basic design based on the stolen F90 Gundam F90 [https://static.wikia.nocookie.net/gundam/images/7/7f/F90_Unit_2_FF_Ver.png/revision/latest?cb=20241009034927&format=original Unit 2] and developed the Late Model version and it become the basis of their RF mobile suit series.
History
In U.C 0116 Several RF Zaku Early Type were participated during a terrorist attack in Side 4 Frontier 1 colony by Zeon Remnants. During the attack these RF Zakus manage to caught the local Earth Federation Forces' garrison off guard, and caused some damage to Strategic Naval Research Institute's headquarters, but unfortunately they were destroyed when SNRI deployed the F90 Gundam F90 Unit 3. Sometimes later several RF Zaku Early Type belonging to Zeon Remnants' Legacy Fleet also present during the siege of Trimurti satellite cannon, but was forced to retreat after Legacy Fleet supreme commander Rhein Dragun was killed during the siege. Later in U.C 0120 many RF Zaku Early Type were seen defending Oldmobile Army's Olympus Mons Fortress, but most of them were destroyed by both the Earth Federation's RGM-89 Jegan and the earthquake cause by Olympus Mons' Cannon.
