High Imperial Roman army vs Late Roman army

[Flavivs Aetivs]

The Barbarians still weren't better organized or better equipped than the Romans, even in the mid-5th century, if I might add. It was all based on Leadership - Aetius was very aggressive, committing roman troops to surprise attacks and using its advanced organization and superior equipment to his advantage. It's recorded that the prefect Ferreolus were supplying the Barbarians with equipment and supplies before Chalons, so they'd be better off than Attila's army.
