Minimums for Iranian Lancers are

Any Date
Cavalry Average 4
From210BC
Cataphracts Average 4

So this means after 210BC you must take 4 cavalry and 4 Cataphracts

Is this correct or should the minimum be Cavalry 4 up to 210

It is correct.

So don't use an army after 210 then.

Thanks Nik

Not unless you want catafracts

And only 16 of them, 4 of those being average
Whereas if you take the manoeuvrable cavalry you get 16 (+6 Greek) bases of superior and only 4 crappy averages
