Armor and Weapon Effectiveness

[Flavivs Aetivs]

e.g. would a Hun be able to oneshot a roman legionary wearing hamata from 50m? I guess most propably yes. Would a cretan archer be able to do the same on a 150m distance? Perhaps, but with a much lower propability. Is there any chance to fully penetrate proper roman mail and subarmalis on a 300m distance?

I heard the reason they beat the sarmatians is because they could take down cataphracts before the Alans could close the distance. So a hun could punch mail from over 100 meters, that's for sure.
