Roman Army Units on Hadrian\'s Wall

[Kaeso]

That depends. Either you are asking about the main differences between the army of the Principate and the Late Roman army, or you want to compare certain units?

I was thinking more regionally than the broader question of differences between army of the principate and late roman army. If you take the legionaries and auxiliaries from Hadrian's reign and compared them with the soldiers stationed on the Wall in the late 4th century, how different would they be? would the equipment they use bear much resemblance to their earlier counterparts? would they have similar ethnicity or would they have a very different more localised culture? how different would the unit sizes be? that's the type of thing I'm interested in finding out.

Thanks,
