Rome, Greece, Egypt, Sparta, Mongolia, etc all had professional armies. Vikings didn't conscript soldiers. You volunteered to raid. And sure as heck were not fighting 1v1... seriously? I'm not sure what this post is about.
Also should be said, the staple of most ancient armies was a spear/pike/javelin to thrust at enemies behind the shield wall.
Romans legions would carry two javelins, a sword and a dagger. The would attempt to throw both javelins before engaging. Then use the sword behind their massive shield walls. Does this sound like a poorly equipped barely trained peasant?
A 101 history course would teach you war is about columns of men trying to outflank their enemies using strategy. Or just outright overpowering them with superior weapons.
And... um there were definitely horses used in war throughout the history of warfare - it was the bane of footmen and archers. Horses quickly covered terrain and could outflank enemies. That is not a hollywood made myth.
But yeah, medieval times were not a great time to be around. But, that is small part of history, and certainly not ancient...
