Roman Army before and after the Marius' Reforms

[Dan Howard]

Hey Dan, you want to weigh in on this, since you're the armor guru? Do we know how much mail cost during the Republic?

10,000 Drachmae was the wealth requirement for enrolment, not the cost of the armour. We don't know how much mail cost, we don't know how much of the army wore armour, and we don't know how much of each kind of armour was worn. All we can really say is that more of the Roman army wore armour than most of their opponents.
