Roman Legion composition?

[Lanceari]

Historically, a Polybian maniple had about 120 men, while a post-Marian maniple would have a paper strength of 180 (typo: correct number is 80 x2 = 160)... A Polybian cohort had 360 men, while a post-Marian cohort had 480 men. A Polybian Legion had 3,600 legionaries, while a post Marian legion had 4,800 legionaires (plus supporting units).

I set EB to huge size units. EB Polybian units had 160 men, while EB post Marian units have 200 men.

I think of a legion as having a total of 40 units: 24 EB units of legionaries, plus another 16 supporting units. My legion has to be split in two stacks.
