It doesn't specifically say that we're "super soldiers." We're merely revived by the travelers light. Our technology advanced hundreds of years when the traveler arrived and we eliminated sickness and commonplace scientific problems. We learned to store physical things as data including our physical selves. Yes our armor is far more advanced and probably provides us with increased stamina and durability. Super strength however is a different issue. Muscles do have a maximum lift limit and having them at a constantly increased capacity could shred them and shatter our bones. And no problem I enjoy friendly debates in these forums. A lot of people have really great ideas on the story and other things.
