Following on from this question, a fantasy setting exists where physical training has no limits and those dedicated enough can become super-fast, super strong and perform incredible feats.
Unfortunately the pressures of life mean the majority of people don't have the time or inclination to spend 5 plus hours a day training to move mountains so the number of superbeings remains low, though anyone in a profession which involves fighting such as the town guards, bandits, knights and the kings standing army would outclass everyone else by a large degree.
So if different nations in this setting come to a disagreement that only war will settle and decide it is time to call up the serfs to raise a larger army, how would the untrained masses fare against a small but vastly powerful group of regular soldiers?
Something I should note is no ruler is a complete monster and sending out raw recruits as a distraction or meatshields will reflect badly on the kingdom. We want to be able to use the commoners as usefully as they can be, without suicide missions.
