Following the "first descent strategy" towards Africa with the main objective of securing materials such as mineral resources, the "Zenkoku invasion strategy" by the Zeon military forces is the main objective to capture the military facilities of the Earth Federal Forces Expanded to the "second descent strategy" to the North America that it did. The Earth Federation Army, which was hit by surface trampling by mass weapons such as "Colony dropping" and was in a state of confusion, was also deprived of the military development base "California base" of North America by the military force.
With the "California base" gained, the Zeon duty army used its development facilities to promote the establishment of a submarine corps and mass production of Gau attack carrier aircraft, and to introduce additional fighting power to the front lines in each direction. In addition, we will utilize it as a development base for new MS. We support Zeon ground fighting power since the middle of the one year war such as "MS - 07 GUFF", "MS - 09 DOM", as well as Zaku type local refueling modifications such as "MS - 06 D" and "MS - 06 K" Milestones were created from this base.

However, in the war death of Garmama Zabi in the latter half of the war, in November, Zion and the Earth Federation have become aware of the fact that Zebra and the Earth Federation ended in failure due to the failure of the "Jaburo descent operation" that put in most of the "California base" The situation is reversed. The Earth Federation Army launched a massive amount of proprietary MS "RGM - 79 Jim", developed the anti - US strategy of North America, and finally succeeded in recapturing "California base". Some of the residual strength of the Zeon government forces who were forced to flee escaped to outer space, and some gassed as well as "African front".

The independence war by Zeon Duchy, later called "One Year War" was originally supposed to be a short-term decisive battle. However, after the "one week war" and "Lumium battle", the prolongation of the war became definite, and Zeon Duchy, a country with poor goods, fell into a dilemma. "Strategy for Invasion of the Earth" is a necessary strategy for Zeon to secure the battle capability overturning the situation, the purpose was to take the development base and acquire resources.
Among them, the Africa direction is an important area that has the purpose of holding down various resources including the Middle East and the aspects as a foothold to the European capture under the Earth Federation, and the invasion troops are primary, secondary and many It was sent in and the suppression was made certain. The strategic resources acquired here sufficiently support Zion's logistics, and the mining base commander Mr. Kubbe left the word "Zion can fight for ten more years."
At the time of pressure control, the air fighting power centered on the Gau attacking aircraft carrier was the main axis, and the three-dimensional tactics MS used in conjunction with this was used.

In particular, with the successive introduction of the MS-06D ZAKU DESART TYPE, a machine specialized for the desert, and the cutting-edge MS-09 Dom, which excelled on rough terrain, the nature of ground battles changed dramatically, and MS became the core of maintaining the front lines.
However, due to the victory of the Earth Federation Army in "Operation of Odessa" in November of the war, Zion's Middle East and European strength will be totally destroyed, and its influence will extend to the mainland of Africa. At last the Federal Army made a mission to Africa sweeping and Zeon fighting power in Africa, which joined with the defeat power from Europe, tried to withdraw into space, and in part attempted thorough anti-warfare. The scout fight continued even after the end of the "One Year War", but the remaining Zeon fighters scattered on the vast African continent skillfully hid and expanded guerrilla warfare for a long time even after one year war. Especially in the "primary neo-zeon conflict" of UC 0088 and at the "third neo-zeon conflict" in UC 0096, etc., they are standing out in a standout manner, showing great rebellion while keeping old-fashioned strength intact ing.

A man-made mobile weapon = a mobile suits that Zeon Democratic Army developed and brought to the battlefield and greatly changed the concept of subsequent weapons. Initially at the time of development, it was aimed at acquiring mobility and mobility with a higher degree of freedom than fighter aircraft and ship by making it humanoid on the premise of operation in space. Moreover, by combining "versatility" that we can instantly cope with the long range shooting from proximity battle to the operated war stations and tactics, just by changing weapons, the practicality as a mobile suits weapon is It increased. However, this "versatility" was innovative at the outset of the war, but the operation of the mobile suits became normal, and when the mobile suits development began on the Federal military side, the situation changed completely. Like the flow of weapons that have been walking, the mobile suits will also head towards "evolution", and various machine variations will be born in the development history.

The evolutionary system of the mobile suits for space is largely divided into two. One is 'application-specific' which will sharpen the functions to carry out specific tasks. Because main purpose mass production machines such as MS - 06 Zaku and RGM - 79 gym are aimed at high versatility, they are not excelled in electronic devices such as sensors and basic armament, but productivity and maintainability etc We emphasize included operability. However, as the war grows, the aspects of some operational strategies and applications in the battlefield, where general equipment is lacking in on-board equipment and arming performance during operation will become apparent. For example, "mine scattering" which can not be operated unless it has a specific equipment other than armed, and "forcible reconnaissance" which requires strengthening of communication equipment such as cameras are required to perform tasks unless sacrificing versatility Can not be satisfied, and improvements will be made in a form specialized for those applications. Also, the development of aircraft that leaves the category of conventional weapons concept, which a special pilot called New Type will board, will also be classified as "application specific type".
Another is 'performance improvement type'. Mass-production machines such as MS-06 Zaku and RGM-79 can handle the performance of aircraft, such as mobility and maneuverability, if there is a specific maneuvering skill so that ordinary pilots can easily maneuver, balance is It is completed in a form taken. However, from repeated pilots, some pilots who improved their skills, in order to fight more efficiently, seek further performance, such as mobility, mobility, aggression and defense performance, or improve the performance of the entire aircraft My voice came up. In addition, while maintaining versatility to some extent, it is sometimes required to improve the performance of some functions of the aircraft, against special missions such as anti-ship attacks making full use of mobility and battle close to fighting fight between mobile suits. It was. In such a sense, listening to the voices of the workplace, the variations of the aircraft born by the corresponding improvement are classified as "performance improvement type". And, the performance of variant machine of "performance improvement type" is operated in the battlefield and accumulated as battle data, which leads to the development of mass production machine of the next generation having higher performance.
Variations of ground mobile suits, which were often used for "local combat" in various regions and environments under gravity, are often required to have specific functions, and many "application specific type" are produced It was decided. On the other hand, in the space where the environment of zero gravity is the battlefield, it is important to fight efficiently by raising the performance of the aircraft, and as a result, there is a strong tendency to develop a lot of mobile suits of "performance improvement type".
