I have a question about EB. Is there any way I can get to have a historically accurate Roman Legion size because according to sources, a Republican Roman Legion had about 4500 troops each. 30 Maniples of Hastatii, Principe, and Triarii. Each with 60 troops. And about 1200 Velites and 300 Cavalry.

So my question generally is, how can I get this amount of troops? Since this is the correct size of a legion.

Thank You!
