Super Soldier: Most successful galactic militaries and mercenary organizations tend to have a favorite package of military-specialized genetic enhancements, nanoviruses, and implants; these days, receiving at least the “military-basic” upgrade package (a whole shopping list of enhancements on top of the already impressive alpha baseline, for the Empire’s version) – usually sometime around the midpoint of basic training, once they’re reasonably sure you’re not going to snap on them and quit – is more or less necessary to compete on the battlefield, especially as regular not-in-the-combat-exoskeletons infantry. (Although, commonly enough, those troops have their own upgrade requirements.)
Super Senses: Naturally, with various enhancements here and there, with the new Imperial baseline involving enhancing vision to include a substantial chunk of infrared and ultraviolet (everything from 500 nm through <300 nm), better imaging resolution, low-light sensing and thermal imaging, better sensitivity to motion, angle, and range, and – which so many of these miss – flare protection (actually, they all come with overload protection); hearing gets better amplitude sensitivity (to -50 dB) and frequency sensitivity (16-35,000 Hz), direction-finding, perfect pitch, and a sense of rhythm; smell gets closer to the bloodhound’s nasal skill, and taste likewise; touch enhanced with greater sensor density and acuity (and this, incidentally, is why people pay such attention to the comfort and texture of clothing and furniture); balance, rotation and acceleration senses are no longer troubled by rotating frames of reference or microgravity; pain detection is gateable; and the time sense becomes much more accurate.
(Parallel-type enhancements apply to species which were endowed with different senses by nature, of course.)
Of course, that’s just the existing senses. Then come things like the entirely new sense for static and dynamic EM fields, synthetic additional visual fields and auditory channels for augmented-reality information, and senses operating through the Transcendent hyperconsciousness permitting the recall of memories never experienced and the direct sensing of nature, meaning, utility, entelechy, and obligation…
