Units tend to follow the organization set down in Gates of Hell by Dicefreaks. Thus,a squad is 9 devils (diminutive), a platoon is 81 devils (medium) and a company is 729 (gargantuan). The army blocks are designed for mass combats, although some of the higher level ones are downright apocalyptic. I suppose that's appropriate, if 700 pit fiends show up and start blowing things up, it might as well be the end of your world. Most likely though, mass combats using diabolical armies will use Medium sized or smaller armies, so that's what I focused on.
