The revolution in warfare brought by the Hardwar doctrine has minimised the role of biological combat units due to their insufficient combat capabilities and extensive needs; therefore, human soldiers not associated with heavy support were almost completely reduced to logistics and security assignments. However, with the development of cybernetics, scientists who were looking for cheap and efficient hardware for infantry to run on allied with the oldschool military who were longing for more active involvement of human troops in frontline operations. The new infantry had to be at least competitive to the unmanned drones such as the assault droids in terms of damage resistance, and the breakthroughs in material engineering made it actually possible to build a walker not much larger than human which could be piloted from the inside. This miniwalker, or actually a robotic armour suit, has quickly proven to outperform its robotic counterparts in almost all types of missions, bringing all human strengths and weaknesses back to the midst of the war. Full-fledged power armours were expensive to build, but thanks to their users - always top elite of their kind - they were also much more efficient and difficult to destroy than any other type of infantry. As usual, this technology subsequently found its way towards various civilian applications, introducing robots which were were more akin to organic creatures than ever - both in complexity and reliability.
