Who can help me explain the whereabouts of those gundam seed troops?

Plants are countries that colonize satellites in satellite orbits. Basically, people born through gene regulation technology are called regulators. They are much better than ordinary human beings in both intelligence and physical quality, and zaft is their army. However, many ordinary people on the earth are very repulsive to this, so the two sides have formed an antagonistic situation. The United earth army is the earth army against zaft. Because of the regulators' own advantages, they gained an advantage in the R&D and application of MS, that is, mobile suit, so the United Army of the Earth secretly developed five Gundam to counter this advantage, so the event that zaft grabbed Gundam at the beginning of the seed happened. Although the United Army of the Earth has developed Gundam, it is found that ordinary people can't drive at all, so the Gundam driver of the Earth Army, who appeared in the later stage of Seeds, is an enhanced person. Ordinary people can drive Gundam like Uncle Mu, because the auxiliary system was developed with the help of Kira, so in the later stage of SEED, Aubrey had mass production Gundam Rain and heresy that ordinary people could drive. Aubrey is a neutral country and does not exclude natural persons and regulators. This is a country where two kinds of people can coexist. Therefore, it has an advantage over the earth army in technology, but it is also sandwiched between the two major forces, but it has always supported the policy of neutrality and uncompromising.
