No idea.

So what's the General Idea for whatI should do for the Imperial-era armies? Would the Cohors Evocata just be replaced by the Imperatoriana? Also, What should my Imperial Guard be made up of? I was thinking 2 Units of Cohors Praetoriana, 2 Of Antesignani/Reformata, with 2 Archer Auxilia, 2 Equites Praetoriana, and 2 as-of-yet Unknown Javelinmen. Is this historically accurate, and if not, how can I make it so?

PS: sorry about the lack of spelling with my earlier posts, I was doing them on my phone.
