I understand that the Roman Army would preferably use Cretan archers, but to be honest I already have these for my Greek/Macedonian army, and I wanted to distinguish the Roman mercenaries from the Greek ones. To combat this, I used Newline Designs Maccabean archers and slingers, and by giving the archers all red tunics and the slingers red headbands, I felt it gave them a more roman appearance, what do you think?
