Slitherine

I saw on a Slitherine web page that the unit scale is "squad or cohort".

How many men are comprised in a squad/cohort (for an average 1000 strenght unit) ?

Does a squad/cohort correspond to a "regiment" or a "batalion" in our modern army ?

The units in the Slitherine scenarios have 1500 men for heavy infantry, 1000 for cavalry, 500 for light troops as their initial strengths. Some user created scenarios differ from that.

A Roman unit of 1500 heavy infantry would represent roughly three cohorts (paper strength in real life 480 men) or, 18 centuries (80 men). Or in earlier Republican times, 9 maniples. The Romans had no tactical unit of 1500 men. Their units were:

Century (80 men)
Maniple (160 men) or later the cohort (480 men)
Legion (4800 men).

These would correspont very, very roughly to company - battalion - brigade in modern terms, but to be honest the comparison isn't a very good one, except possibly the century-company one. Modern soldiers primarily identify with their battalion/regiment, a Roman would identify with his legion (a higher order structure).

Thank you very much for this crystal-clear answer.
