Rome vs Han essay- want get some opinions

[Dan Howard]

It seems odd to me that it wasn't until the turn of the 2ndC AD that the Romans decided to, en masse, increase the reinforcement of their armour, as well as increase the use of manicae and ocreae. That coincides with the Dacian Wars, where we know they had trouble against the falx. Logically, that means barbarian swords were not a real threat to their armour prior to then, otherwise we should see even more evidence of the supplemental armour than we do. I think it all was in use before the Dacian campaigns, but not as much.

All throughout history the same thing is evident. If armour didn't protect adequately against the most common threats then it was either reinforced till it did, or it was discarded completely.
