Late Roman Unit Sizes

[Robert Vermaat]

I doubt it, actually - that division would appear to date initially to the 350s at least, which would perhaps put it in the same era, but I would guess it was more about army reorganisation than unit reorganisation. I think we're looking at a series of changes coming in over about 50-75 years or so, perhaps not all as part of the same connected plan!

In your description you see what is also described as the process for the creation of iuniores units - a smaller part detached from a parent unit and being enlarged afterwards.
If the process happened as in your model, how would you propose those detachment were named? And wouldn't we see that somehow in any records?
