The Spartans were infused with a lot more than Serum. Ceramic coating on their bones to make them virtually unbreakable, protein infusions on their muscles to make them denser and decrease lactase recovery time, as well on surgeries on their eyes and superconduction of the neural dentrites, making their reaction time human times three, along with a handful of other modifications. Cap can survive a jump from a plane? Spartans survived a drop from outside the atmosphere (granted, with their armor). I would say that, 117 would at least be an equal match against the Cap physically speaking.<br/><br/>In terms of intelligence, that too has been increased with the Spartan mods, along with battle training and conditioning from when they were six years old, fighting on a nearly daily basis from when they were 16. The Cap had a hard time with the Winter Soldier, whereas 117 has been fighting Covenant Elites (At least an equal match, with their own armor and weaponry to the Winter Soldier) for years. MC has the advantage on that score, and it is a pretty critical edge.
