In order to avoid a demographic crisis, the usage of "Rebis" was strongly limited by the government. An attempt was made to divide people by "social responsibility level", harshly defining a citizen's value for society and giving them the right to benefit from buying and using these drugs and implants.
Of course, the number of citizens deemed worthy enough appeared to be low—it was mainly Officials of all kinds, celebrities and CEOs of big corporations. For ordinary citizens, the price of "Rebis" remained unattainable.
"Rebis" and battle implants actively broke into military structures. Thanks to the fast developing battle implants, the combative value of individual soldiers increased. Eventually, the government acquired the rights over all implants and "Rebis", which bound every enhanced one to serve for them. In case of denial, they would lose their implants, leaving them handicapped. This is why most of the militants are forced to stay, without any opportunity to leave the service.
