Cohort (military unit)

A cohort (from the Latin cohors, pl.: cohortes; see wikt:cohors for full inflection table) was a standard tactical military unit of a Roman legion. Although the standard size changed with time and situation, it was generally composed of 480 soldiers.^[1] A cohort is considered to be the equivalent of a modern military battalion. The cohort replaced the maniple.^[2] From the late second century BC and until the middle of the third century AD, ten cohorts (about 5,000 men total) made up a legion. Cohorts were named "first cohort", "second cohort", etc. The first cohort consisted of experienced legionaries, while the legionaries in the tenth cohort were less experienced.
