The "ubersoldaten" was an umbrella term to describe the genetically and cybernetically re-engineered young human super-soldiers that saw service during the Thousand Day War against the Ice Warriors. The modifications included augmented nervous systems (which robbed the recipients of the ability to dream), increased strength, enhanced reflexes and spatial perceptions, all of which could be further boosted via specially designed combat drugs. However, the people undergoing these procedures were deliberately sterilised to prevent the biological and legal problems that would arise from passing on corporately-owned genetic sequences to their offspring.
