Gene manipulation is Jekotian and nanite enhancement is Brenodi. On the outside, the soldiers of both sides look pretty much like a normal human but with more endurance and strength thanks to such modifications. However I though whatever some people on both sides decide to take their enhancements to a far end in order to achieve victory. I mean more gene-tinkering than allowed and too many injections of nanites. I say that too much gene-tinkering on a NF soldier and you get something like the Tyrant from Resident Evil along with loss of humanity. Too many nanites in the blood would probably result in the development of Borg-like features if something ever malfunctions to those tiny machines. Hivemind is optional. I mean there has to be some incidents in the Empires universe where some people on both sides took their tech to a really wrong end of the spectrum.
