Late Roman Unit Sizes

[ValentinianVictrix]

In a previous thread on the Late Roman Army I cited the example given in Ammianus where the Batavi and the Heruli Auxilia Palatina units were paired to the extent that they even shared the same standard.

We also discussed the strange passage in Ammianus where he appears to mistakenly called the Iovii and Victores 'legions'. However, we must be very cautious here. We know that the surviving copies of Ammianus were damaged in parts, we have no idea if the copy all the surviving copies were based on was damaged in this particular part and the person copying it put 'legion' at that paoint because they did not know there were Auxilia units with the same name.

Correct me if I am wrong but doesn't Ammianus give the reason why the Regii were called the Regii? I don't read Italian but this person put the case forward for King Crocus as being the founder- Maurizio Colombo, "Constantinus rerum nouator: dal comitatus dioclezianeo ai palatini di Valentiniano I", Klio, 90, 2008, p. 124–161
