Roman infantry vs medieval

I think Roman infantry would be better than European medieval infantry. If Europeans didin't have archers or longbowmens They wouldn't have a chance against Roman Legions. Only Hussites and Swiss could give Romans a good fight. Medieval European infantry was pathetic except 2 above mentioned and longbowmens but You probably meant that both sides don't have archers and longbowmen.

Medieval army was based on heavy knights so infatry wasn't that important like in Rome.

Roman aqueducts might have been superior but their metalurgy was greatly inferior. Medieval weapons and armour far supassed Roman in both strength and quality. Also in standardisation, unlike the medieval era the Romans never achieved any kind of standardisation of production and in a single unit identical peices of equipment could vary greatlely in design and quality having been made by different smiths.

Roman would have had some edges over medievals such as Marines, Engineers, Fortified Encampents and regular forces which probably could give a feudal medieval army a run for it's money. But from a high period onward where forces became more regular, the equipment gap would be too great.

Saxon and viking used sheild wall tactics like the romans,maybe not as disciplined but making up with it in ferocity.later we see medieval infantry becoming more adapted to fighting cavalry.Historians used to think that the crusaders infantry force was undisciplined but they were used close support for the knights charge.

So infantry evolved to be a support group for a cavalry charge.something the knights could rally behind a line of spears.and once in melee with enemy cavalry infantry would run behind and protect flanks from enemy.

How effective medieval armies would be without its cavalry arm is the question against the roman army which although did use cavalry it was mainly infantry based more than most histories armies.

okay Pre Full plate armour which is 15thcentury ,medieval times troops are armoured with chain mail armour,which is much different than armour that rome or its enemies used..

Lets imagine now that dismounted knights or medieval infantry are fighting the romans who are using sheild wall tactics to fight the medieval knight with big swords,would the knight be nullified like the celtic warriors

*i meant to say "which isnt much different than roman armour",

i did it at work lol but thanks for the confirmation of early medieval times.Later medieval times sees a movement in the long weapons halberds,long swords etc did these troops keep their formatation?
