This chapter argues that the symbiosis of humans and modern technology (‘cyborg’) does not represent a transitional stage to a machine civilization in a transhumanist sense. In this respect, the following argumentation can be seen as a contribution to a posthuman debate. However, the perspective here differs from an understanding of posthumanism that, in the wake of a ‘symmetrical anthropology,’ mitigates fundamental differences in competence levels through symmetrization. In detail, the regulator model is presented first. Then the concept of human cyborgs is developed. Based on this, questions for posthumanist social theory are formulated and an idea of human dignity is explored. In the following chapters, the developed perspective is related to the military context. On the one hand, this should make it easier to understand what ethical enhancement can mean. On the other hand, ethical problems of posthuman social theory become evident. In addition to Plessner, the article also draws on Niklas Luhmann, but does not attempt to synthesize the two approaches. The focus is on understanding the phenomenon of the cyborg soldier, using both models as tools.
