Are the armies being used for playing a wargame version of an historical battle? My contention would be, if the battle is not historical, then no point worrying about units.
In my rules, the difference between a quingenary unit and a milliary one does make a difference - one is Small and the other Medium, giving rise to a concomitant difference in fighting capability.
In reality things do not seem to have been simple - as is often the case with armies there are exceptions. Consider, for example, the First Cohort of Tungrians, stationed at Vindolanda towards the end of the first century AD. On one day in the May of an unknown year, it had a strength of 751 men, and six centurions. Six centurions would indicate, to our eyes, that it ought to be a 'quingenary' cohort, with 480 men, but its size suggests that it is a slightly under-strength milliary cohort - though with a shortage of centurions. Was it being converted from one to the other? What is the story here? I suspect we'll never know for certain, but the one thing it definitely tells us is that our view of the Roman army is nothing like complete.
